A reversed-phase ion-pair chromatog. method using direct conductivity detection was developed for the determination of hexafluorophosphate(PF^–₆) ionic liquid anion. Chromatog. separation was performed on a Diamonsil C₁₈ reversed-phase column using ion-pair reagent-citric acid-acetonitrile as mobile phase. The effects of ion-pair reagent, volume fraction of acetonitrile, pH and column temperature on the retention factor and separation of PF^–₆ were investigated. The mechanism of retention in the separation was discussed. The optimized chromatog. conditions for the determination of PF^–₆ were using 0.05 mmol/L tetrabutylammonium hydroxide(TBAH)-0.038 mmol/L citric acid-35% acetonitrile(pH 5.5) as mobile phase, at a flow rate of 1.0 mL/min and a column temperature of 40°C. Under the optimal conditions, the retention time of PF^–₆ was less than 15 min and the baseline separation of PF^–₆ was achieved without any interference by other common anions(Cl^–, NO^–₃, F^–, Br^–, SO^-2₄ and BF^–₄). The detection limit(S/N=3) for PF^–₆ was 0.25 mg/L. The good linear relationship was obtained between chromatog. peak area and concentration of PF^–₆ in the range of 0.5-100.0 mg/L. The relative standard deviations(RSD, n=5) of chromatog. peak area and retention time were 0.17% and 0.15%, resp. The proposed method was applied in the determination of PF^–₆ in ionic liquids of 1-butyl-3-methylimidazolium hexafluorophosphate and 1-propyl-2, 3-dimethylimidazolium hexafluorophosphate. The spiked recoveries of PF^–₆ were 99% and 104%, resp. The good linearity and repeatability of the method could meet the requirements for the quant. anal. of PF^–₆ in ionic liquids The method is simple, accurate, reliable and practical.

The structural diversity and photoluminescent properties of cadmium thiophenedicarboxylate coordination polymers was written by Xue, Li-Ping;Chang, Xin-Hong;Li, Shi-Hui;Ma, Lu-Fang;Wang, Li-Ya. And the article was included in Dalton Transactions in 2014.Formula: C11H9N5 The following contents are mentioned in the article:

Two series of Cd(II) coordination polymers (CPs), {[Cd(bimm)₂(H₂O)₂][(3,4-tdc)₂][H₂O]₂}_n (1a), [Cd(3,4-tdc)(bimb)]_n (2a), [Cd(3,4-tdc)(bimpy)(H₂O)]_n (3a) and [Cd(2,3-Htdc)₂(bimm)₂]_n (1b), {[Cd(2,3-tdc)(bimb)](H₂O)}_n (2b), [Cd(2,3-tdc)(bimpy)(H₂O)]_n (3b) where H₂tdc = thiophenedicarboxylic acid, bimm = 1,2-bis(imidazol-1′-yl)methane, bimb = 1,2-bis(imidazol-1′-yl)butane and bimpy = 3,5-bis(imidazol-1′-yl)pyridine, have been synthesized by using Cd(II) acetate with H₂tdc and N-donor ligands under hydrothermal conditions. Two related isomeric thiophenedicarboxylic acids were chosen to examine the positional isomeric effect on the construction of these CPs with distinct dimensionality and connectivity. The structure of 1a is a one-dimensional (1D) cationic double chain further forming a two-dimensional (2D) supramol. network via hydrogen-bonding interactions, while 1b exhibits a neutral double chain structure. A three-dimensional (3D) 4-connected cds network for 2a as well as a 1D neutral double chain structure for 2b were obtained in the presence of bimb. When the rigid tripodal bimpy was introduced, isomorphous 3a and 3b with 3D (3,5)-connected (6²·8) (6⁷·8³) nets were constructed. The structural diversity of 1a–2b mainly stems from the positional isomeric effect of thiophenedicarboxylate, while 3a and 3b are well regulated by rigid bimpy. Moreover, the thermal stability and photoluminescence of 1a–3b are investigated. This study involved multiple reactions and reactants, such as 3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6Formula: C11H9N5).

Room temperature ionic liquids (RTILs) have emerged as tunable and potentially “greener” solvents for a multitude of applications. To investigate the solvent properties and potential use as a thermal fluid, a study was initiated to determine the effects of anion type, C-2 hydrogen substitution, and alkyl chain length on the flammability, thermal stability, and phase change characteristics of 1,2,3-trialkylimidazolium room temperature ionic liquids A Setaflash flash point apparatus was used to determine the flammabilities of the RTILs. No flash points were detected for any of the imidazolium based RTILs below 200°, the maximum temperature of the instrument. The thermal stabilities of the RTILs were measured using the technique of thermogravimetric anal. The 1,2,3-trialkylimidazolium compounds exhibit slightly higher thermal stabilities than the comparable 1,3-dialkylimidazolium compounds; RTILs with nucleophilic anions decompose about 150° lower than RTILs with bulky fluoride containing anions; the alkyl chain length does not have a large effect on the thermal stability of the RTILs; and the pyrolysis decomposition exhibits higher thermal stabilities via a different mechanism than the oxidative decomposition In addition, it was found that although the calculated onset temperatures were above 350°, significant decomposition does occur 100° or more below these temperatures The phase change behaviors of several imidazolium based RTILs were characterized by differential scanning calorimetry. The m.ps. of the RTILs increased with increasing alkyl chain length. Most of the salts studied exhibited significant undercooling, which decreased as the length of the alkyl chain was increased. The hexafluorophosphate and bromide RTILs exhibited polymorphic and liquid crystalline behaviors as the alkyl chain length was increased above C10. The clearing point temperatures increased more rapidly with alkyl chain length than the m.p. temperatures This study involved multiple reactions and reactants, such as 1,2-Dimethyl-3-propyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 157310-73-1Safety of 1,2-Dimethyl-3-propyl-1H-imidazol-3-ium hexafluorophosphate(V)).

Levulinic acid (LA) has been identified as a promising green, biomass derived platform chem. Response surface anal. (RSA) with a four-factor-five-level central composite design (CCD) was applied to optimize the hydrolysis conditions for the conversion of bamboo (Phyllostachys Praecox f. preveynalis) shoot shell (BSS) to LA catalyzed with ionic liquid[C₄min]HSO₄. The effects of four main reaction parameters including temperature, time, C_[C4min]HSO4 (initial [C₄mim]HSO₄ concentration) and X_BSS (initial BSS intake) on the hydrolysis reaction for yield of LA were analyzed. A quadratic equation model for yield of LA was established and fitted to the data with an R² of 0.9868, and effects of main factors and their corresponding relationships were obtained with RSA. Model validation and results of CCD showed good correspondence between actual and predicted values. The anal. of variance (ANOVA) of the results indicated that the yield of LA in the range studied was significantly (P < 0.05) affected by the four factors. The optimized reaction conditions were as follows: temperature of 145°C, time of 103.8 min, C_[C4min]HSO4 of 0.9 mol · L^-1 and X_BSS of 2.04% (by mass), resp. A high yield [(71 ± 0.41)% (by mol), triplicate experiment] was obtained at the optimum conditions of temperature of 145°C, time of 104 min, C_[C4min]HSO4 of 0.9 mol · L^-1 and X_BSS of 2% (by mass), which obtained from the real experiments, concurred with the model prediction [73.8% (by mol) based on available C₆ sugars in BSS or 17.9% (by mass) based on the mass of BSS], indicating that the model was adequate for the hydrolysis process.

Eco-efficient and green method for the enhanced dissolution of aromatic crude oil sludge using ionic liquids was written by Sakthivel, Sivabalan;Velusamy, Sugirtha;Gardas, Ramesh L.;Sangwai, Jitendra S.. And the article was included in RSC Advances in 2014.Application of 478935-29-4 The following contents are mentioned in the article:

The upstream petroleum industry faces operational and tech. problems due to increased deposition of waxes, aromatics and asphaltene from crude oil sludge in oil storage tanks in the form of tank-bottom sludge (TBS). This results in huge production losses, and threatens environmentally safe operation; therefore, safer solutions are needed. In this work, nine aromatic ionic liquids (ILs) are synthesized and tested for the dissolution of TBS with the aid of five solvents, namely, toluene, heptane, decane, Et acetate and hexane. The UV absorbance values of the standard solutions (TBS in solvent) are compared with the sample solutions (TBS in solvent + ILs). It is observed that ILs significantly improve the dissolution of TBS in solvents compared with neat solvent alone. Different weight ratios of TBS : ILs (1 : 1, 1 : 0.5 and 1 : 0.1) are considered in this study. Ionic liquids (ILs) based on an imidazolium cation and various anions, such as [Cl]^–, [Br]^–, [BF₄]^–, [H₂PO₄]^–, [HSO₄]^–, and [PF₆]^–, are considered in this investigation. It is observed that the dissolution of TBS in heptane in the presence of [HMIM]⁺[Br]^– is efficient to a maximum extent of 66% with other solvents showing similar increased solubility effect with various ILs. In the case of hexane, it should be noted that the efficiency of dissolution of TBS goes on decreasing with increasing concentration of TBS in hexane. A hold-time study is also performed with heptane containing ILs and heptanes without ILs to determine the maximum time required for efficient dissolution of TBS. It is observed that the efficiency is increased beyond 66% in the presence of ILs for the dissolution of TBS in heptane, provided that the mixture of solvent and ILs are in contact with the TBS for a prolonged period of 30 days, or even longer as required. FT-IR and ¹³C-NMR spectral analyses are also performed so as to understand the efficiency of the ILs in the dissolution of TBS in various solvents, and it was observed that there is a decrease in the intensity of the peaks in the spectra of treated TBS with solvents, which is further enhanced by the addition of ILs.

Highly selective, sensitive and stable three-dimensional luminescent metal-organic framework for detecting and removing of the antibiotic in aqueous solution was written by Wu, Ruixue;Bi, Caifeng;Zhang, Dongmei;Fan, Chuanbin;Wang, Lulu;Zhu, Bin;Liu, Wenbo;Li, Nana;Zhang, Xia;Fan, Yuhua.

An efficiently selective sensor for aquatic antibiotic detection based on a photoluminescent cadmium metal-organic framework (Cd-MOF) is researched in this work. The novel and simple luminescent MOF that composed from aπ-electron rich ligand bip (3,5-bis(1-imidazol) pyridine) and H₃L (2-nitro-5-(4-carboxy-2-nitrophenoxy) isophthalic) was synthesized in hydrothermal condition and characterized. Single crystal X-ray diffraction anal. demonstrated that it had an uncommon 2-nodal (3,6)-connected 3D framework with a (3²·4)(3⁴·4⁶·5³·6²) topol., which could be formulated as [{[Cd₂(HL)₂(bip)₂]·H₂O}_n]. Benefiting from its unique framework, [{[Cd₂(HL)₂(bip)₂]·H₂O}_n] can not only respond to the trace quantity of chloramphenicol (CHL) via fluorescence quenching but also show good adsorption capability toward CHL in aqueous solution The selective response to CHL reached up to the ppb level with high anti-interference ability in aqueous phase, and the effective detection of antibiotics had been theorized by D. Functional Theory (DFT) calculation for energy bands of H₃L and antibiotics, which revealed that the cooperation influence on photo-induced electron transfer (PET) process and fluorescence inner filter effect (IFE) made CHL show more sensitive luminescence responses than other exptl. antibiotics. Moreover, because of its specific interactions with analytes and relatively high porosity, the pre-enrichment makes the antibiotic fuller contact and interact with the framework, which improves the overall sensing efficiency toward CHL appreciably. Stemming from the abuse, antibiotics have been considered as the great threat to the health of human race and the sustainable development of society. Therefore, it is extremely important to achieve new technol. to detect and absorb antibiotics residues in water. This work proves that metal-organic framework complexes can conform the performance of detecting and removing antibiotic in aqueous environment, that emphasizes the application of luminescent MOFs in contaminant monitoring and removing.

Use of Aromatic Ionic Liquids in the Reduction of Surface Phenomena of Crude Oil-Water System and their Synergism with Brine was written by Sakthivel, Sivabalan;Velusamy, Sugirtha;Gardas, Ramesh L.;Sangwai, Jitendra S.. And the article was included in Industrial & Engineering Chemistry Research in 2015.HPLC of Formula: 478935-29-4 The following contents are mentioned in the article:

Enhanced oil recovery is governed primarily by the role of interfacial tension between crude oil and water. Interfacial tension (IFT) of the crude oil-water system is one of the vital factors in the anal. of the capillary forces affecting trapped oil within the reservoir rocks. High salinity and temperature of the reservoirs tend to make researchers search for new surfactants to lower the interfacial tension in crude oil-water systems. The current study hopes to create a move toward solving the above problem through the use of aromatic ionic liquids (ILs) based on imidazolium as the cation and various anions such as [Cl]^–, [Br]^–, [BF₄]^–, [H₂PO₄]^–, [HSO₄]^–, and [PF₆]^– in different concentrations This work involves the study of the effect of concentration, temperature, time, and brine on the fate of surface tension (SFT) of water and interfacial tension of crude oil-water systems. The present study also addresses the trend in the elec. conductivity of ILs in water along with the effect of temperature and concentration of ILs. The study reveals that these ILs are effective in reducing the SFT and IFT of water and crude oil-water systems at high salinity and temperature conditions. In the IFT measurements, a linear decrement with increase in temperature is observed for crude oil-water in the presence of ILs. The interfacial tension of the various imidazolium-based ionic liquids with the crude oil-water system has been measured as a function of temperature by means of the Wilhelmy plate method. The influence of the nature of cation and anion of ionic liquids and of the chain length on the cationic head of the ILs on interfacial tension is also discussed in detail. At increased salinity conditions, unlike classical surfactants, these ILs are found to be more successful. Enhanced efficiency of the drop in IFT using NaCl and IL mixture has been confirmed by measuring the IFT between crude oil and the aqueous solution of IL. The synergism of salt and IL mixture on the reduction of IFT has been observed This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4HPLC of Formula: 478935-29-4).

Influence of the calcination temperature and ionic liquid used during synthesis procedure on the physical and electrochemical properties of Ti/(RuO₂)_0.8-(Sb₂O₄)_0.2 anodes was written by Santos, Marcel O.;Santos, Gessica V.;Mattedi, Silvana;Griza, Sandro;Eguiluz, Katlin I.

The development of synthesis methods to produce efficient anodes for wastewater treatment systems is an important industrial issue. Here, we describe the synthesis and the phys. and electrochem. characterization of Ti/(RuO₂)_0.8-(Sb₂O₄)_0.2 anodes prepared by thermal decomposition The electrodes were prepared using three calcination temperatures (500, 550 and 600 °C) and using 2-hydroxyethylammonium acetate (2HEAA) and methyl-imidazolium hydrogensulfate ((HMIM)HSO₄) ionic liquids (IL) as solvents for the precursors solutions Both ionic liquids used were characterized in terms of water content and viscosity. The 2HEAA IL is almost 10 times more viscous than the (HMIM)HSO₄ IL. The anodes developed were electrochem. characterized by cyclic voltammetry, morphol. factor, electrochem. impedance spectroscopy and accelerated service lifetime tests. The electrodes synthesized using the 2HEAA IL have superior electrocatalytic properties and electrochem. stability than those made using the (HMIM)HSO₄ IL. In addition, the anodes made using the 2HEAA IL as solvent have more homogenous surfaces and higher crystallinity degree than those made using the (HMIM)HSO₄ IL. Among the studied calcination temperatures, combining 550 °C and the 2HEAA IL results in more compact and rough electrode surfaces with the highest electroactive areas and electrochem. stability. Thus, the temperature of 550 °C is suitable for the synthesis of mixed metal oxide (MMO) anodes. The electrodes synthesized using the 2HEAA IL are more efficient in the electrochem. oxidation of the Reactive Yellow 186 dye than those made using the (HMIM)HSO₄ IL. Consequently, the viscosity of the IL used has great influence on the performance of the synthesized anodes. In addition, the high viscosity of the 2HEAA IL results in a lower number of calcinations steps to produce the anodes and, hence, lower production cost. Viscous ionic liquids are therefore promising for the production of MMO anodes via thermal decomposition methods. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Formula: C10H20N2O4S).

This work reports the synthesis of 3-bromo-benzimidazolone using melt condensation, its polymerization and functionalization on silica which was extracted from diatomaceous earth in our previous work. The synthesized compounds were characterized using FTIR, NMR, SEM-EDS and TEM. The FTIR and NMR spectra of the synthesized benzimidazolones showed the compounds to have several functional groups: A band due to Si-O-C at 1085.41 cm-1, a broad band at 3380 cm-1 and chem. shifts: pos. distortionless enhancement by polarization transfer (DEPT) 13C peaks (indicating lack of CH2 and CH3 groups), 1H NMR – 11.053 ppm (N-H), 7.086 ppm (Ar-H); 13C NMR – 155.34 ppm (CO), 101.04 ppm (C-Br) characteristic of benzimidazolones. SEM-EDS of the functionalized silica showed a rough irregular morphol. with Si and O as the major elements. Carbon was also present indicating that silica was successfully functionalized with 3-bromo-benzimidazolone and TEM showed interconnected smear-like particles arranged irregularly. The functionalized silica was then applied in the treatment of oily wastewater and factors like initial oil concentration, adsorption dosage and time were optimized using the central composite design of response surface methodol. in the design expert software. The amount of oil adsorbed was obtained by quantifying the total organic carbon using TOC test kits. Results showed that the optimum conditions for oil removal were 6650 mg L-1 oil concentration, with adsorbent dosage of 0.004 g and a contact time of 16 h. Under these conditions, the percentage adsorption was 97.9% with a desirability of 0.99. The materials were therefore seen to be applicable to field wastewaters.
