Five acidic ionic liquids were investigated to synthesize palmitoleic acid polyol esters, the results indicated triethylammonium sulfate offers best catalytic activity. Based on temperature-controlled characteristics of triethylammonium sulfate, we designed a novel method for preparation of palmitoleic acid polyol esters, in which the reaction under relatively high temperature combined with the separation of the ionic liquid under relatively low temperature The optimal conditions to produce palmitoleic acid pentaerythritol esters were obtained, and these include a 6:1 of palmitoleic acid/pentaerythritol, 5% of the ionic liquid, 210°C of the reaction temperature and 3.5 h of reaction time.

Highly efficient separation of phenolic compounds from low-temperature coal tar by composite extractants with low viscosity was written by Liu, Qian;Zhang, Xianglan. And the article was included in Journal of Molecular Liquids in 2022.Application In Synthesis of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate The following contents are mentioned in the article:

Highly efficient separation of phenolic compounds from low-temperature coal tar (LTCT) is significant in the industry. In this work, composite extractants composed of imidazolium-based ionic liquids (ILs) and solvents were used to sep. phenolic compounds from model oil and LTCT. First, the COSMO-RS model was used to screen composite extractants that combined the infinite dilution thermodn. indexes and liquid-liquid equilibrium (LLE) calculations Meanwhile, the separation mechanism was analyzed by σ-profile and σ-potential. Then, the reliability of the COSMO-RS model was validated by LLE experiments and FT-IR. The viscosity of composite extractants with high separation performance was further determined Among the composite extractants, 1-ethyl-3-methyl-imidazolium hydrogen sulfate ([emim][HSO4])/ethylene glycol (EG) was selected as the most suitable extractant in the separation process. The m-cresol extraction efficiency and cumene entrainment were 98.1% and 8.3%, resp., at a [emim][HSO₄]:EG molar ratio of 1:2, a temperature of 25 °C, and a composite extractant: model oil mass ratio of 1:1. Moreover, the viscosity of [emim][HSO₄]:EG (1:2) was only 51.8 cP at 25 °C and decreased by 95.6% compared with pure [emim][HSO₄], which enhanced the mass transfer in the separation process. The [emim][HSO₄]:EG (1:2) could be regenerated and reused without significant reduction in separation performance. Finally, [emim][HSO₄]:EG (1:2) was applied to sep. phenolic compounds from LTCT with a phenol extraction efficiency of more than 99.9% and a neutral oil entrainment of 8.3%, providing a promising prospect for the separation of phenolic compounds This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Application In Synthesis of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate).

Effect of Imidazolium-Based Ionic Liquids on the Interfacial Tension of the Alkane-Water System and Its Influence on the Wettability Alteration of Quartz under Saline Conditions through Contact Angle Measurements was written by Velusamy, Sugirtha;Sakthivel, Sivabalan;Sangwai, Jitendra S..

Depleted matured reservoirs contain almost two-thirds trapped oil, which remains unrecovered even after primary and secondary oil recovery methods. Chem. enhanced oil recovery (EOR) methods involve the usage of chem. agents that improve the mobility of the residual oil by mechanisms involving alteration of wettability, viscous fingering reduction within the pay zone, and interfacial tension (IFT) between interfaces of fluids (oil/water) and rock, followed by reduced capillary forces during flooding. Chem. EOR methods need more research for high saline reservoir conditions. In this work, the effect of six imidazolium ionic liquids (ILs) on the IFT of alkane-water systems and alteration of wettability of quartz surface was investigated as a function of IL concentration (0-10000 ppm) and temperature (288.15, 298.15, 308.15, and 318.15 K). Initially, the effect of the various ILs on the IFT of the alkane-aqueous IL system was studied and compared with the neat alkane-water system. Subsequently, synergistic behavior of the ILs + NaCl (0-200000 ppm NaCl) on the system of alkane-aqueous IL + NaCl was performed and compared with the alkane-aqueous IL system at zero salinity. Thereafter, the wettability alteration of quartz-alkane-aqueous IL and quartz-crude oil-aqueous IL systems, under both zero and high salinity conditions at 298.15 K at atm. pressure, was studied using contact angle measurements. The systems with IL showed an increase of contact angle exhibiting an alteration in the wettability from water wet to oil wet, whereas the systems under saline conditions showed a wettability from oil wet to water wet. A synergistic effect of ILs with salt on IFT reduction and wettability alteration has been detected. It is suggested that longer ILs could be a better option for EOR application. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Safety of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate).

Contact angles and wettability of ionic liquids on polar and non-polar surfaces was written by Pereira, Matheus M.;Kurnia, Kiki A.;Sousa, Filipa L.;Silva, Nuno J. O.;Lopes-da-Silva, Jose A.;Coutinho, Joao A. P.;Freire, Mara G..

Many applications involving ionic liquids (ILs) require the knowledge of their interfacial behavior, such as wettability and adhesion. In this context, herein, two approaches were combined aiming at understanding the impact of the IL chem. structures on their wettability on both polar and non-polar surfaces, namely: (i) the exptl. determination of the contact angles of a broad range of ILs (covering a wide number of anions of variable polarity, cations, and cation alkyl side chain lengths) on polar and non-polar solid substrates (glass, Al-plate, and poly-(tetrafluoroethylene) (PTFE)); and (ii) the correlation of the exptl. contact angles with the cation-anion pair interaction energies generated by the Conductor-like Screening Model for Real Solvents (COSMO-RS). The combined results reveal that the hydrogen-bond basicity of ILs, and thus the IL anion, plays a major role through their wettability on both polar and non-polar surfaces. The increase of the IL hydrogen-bond accepting ability leads to an improved wettability of more polar surfaces (lower contact angles) while the opposite trend is observed on non-polar surfaces. The cation nature and alkyl side chain lengths have however a smaller impact on the wetting ability of ILs. Linear correlations were found between the exptl. contact angles and the cation-anion hydrogen-bonding and cation ring energies, estimated using COSMO-RS, suggesting that these features primarily control the wetting ability of ILs. Furthermore, two-descriptor correlations are proposed here to predict the contact angles of a wide variety of ILs on glass, Al-plate, and PTFE surfaces. A new extended list is provided for the contact angles of ILs on three surfaces, which can be used as a priori information to choose appropriate ILs before a given application.

To discover new nematicides I (n = 1, 2, 3; R = Et, iso-Pr, 4-nitrobenzyl, etc.) a series of novel amide derivatives containing an imidazo[1,2-a]pyridine moeity I were designed and synthesized. Among the title compounds, compounds I (n = 1; R = Pr and n = 3; R = n-decyl (III)) exhibited good nematicidal activities against Aphelenchoides besseyi (rice white-tip nematode), with LC₅₀ values against of 27.3 and 35.9 mg/L, resp., which were superior to that of fosthiazate (45.4 mg/L). Meanwhile, the LC₅₀ value of compound III against Caenorhabditis elegans was 5.7 mg/L, which was superior to that of fosthiazate (77.2 mg/L). Compound III not only binds well to acetylcholinesterase (AChE) of nematodes, but also has a good inhibitory activity against AChE. Thus, AChE may be a potential target of compound III against nematodes. Unexpectedly, compound I (n = 1; R = chloromethyl (IV)) exhibited excellent antibacterial activities with EC₅₀ values of 1.2 and 3.1 mg/L against Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc), resp., which were superior to those of bismerthiazol (68.6 and 77.1 mg/L) and thiodiazole copper (80.8 and 96.6 mg/L). The curative and protective activities of compound IV against bacterial leaf blight were 37.0% and 36.8% at 50 mg/L, resp., which were higher than those of thiodiazole copper (16.1% and 15.5%). In addition, compound IV may inhibit the growth of Xoo by affecting the production of cell membranes and extracellular polysaccharides.

Effectiveness of various solvents in the microwave-assisted extraction of cellulose from oil palm mesocarp fiber was written by Azlan, Nadiah Syafiqah Mohd;Yap, Chiew Lin;Gan, Suyin;Rahman, Mohd Basyaruddin Abdul. And the article was included in Materials Today: Proceedings in 2022.Application In Synthesis of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate The following contents are mentioned in the article:

Cellulose is a valuable resource for organic synthesis owing to its low cost, abundance, and sustainability. However, crystalline cellulose in lignocellulosic biomass is frequently smothered by the recalcitrant amorphous layers of lignin and hemicellulose that limit its extractability. Therefore, this study aimed to find the best solvent to combine with a microwave-assisted method for fast and efficient extraction of cellulose from oil palm mesocarp fiber. Results showed that γ-valerolactone gave the highest average cellulose yield (64.0%), followed by protic solvents viz. 2-butoxyethanol (62.8%) and Et lactate (57.3%), however, there was no statistical difference (p > 0.05) between the three solvents. Crystalline cellulose in biomass seems to interact with aprotic solvent via dipole-dipole interactions slightly more efficiently than with protic solvent via hydrogen bonds. However, as an aprotic solvent, Et acetate showed an exception low cellulose yield (50.7%), presumably due to its b.p. which is lower than the operating temperature Among all, ILs ([BMIM][Cl], [HMIM][HSO₄] and [EMIM][Ac]) performed the poorest giving only 36.0% to 52.0% of cellulose yields. The mixture of [HMIM][HSO₄]/γ-valerolactone (1:1, volume/volume) performed similar to the sole [HMIM][HSO₄]. Overall, the combination of γ-valerolactone and microwave extraction allowed a high yield of cellulose to be achieved within a short period of 2 min, at a relatively low temperature of 140°C, although faint hydrolysis into glucose was detected. The cellulose extracted from γ-valerolactone showed a higher crystallinity index (46.81%) than raw biomass (24.06%), indicating a high purity product and the removal of amorphous portion.

A quantum-chemical-based guide to analyze/quantify the cytotoxicity of ionic liquids was written by Torrecilla, J. S.;Palomar, J.;Lemus, J.;Rodriguez, F..

A COSMO-RS descriptor (S_σ-profile) has been used in quant. structure-activity relationship studies (QSARs) based on a neural network for the prediction of the toxicol. effect of ionic liquids (ILs) on a leukemia rat cell line (Log EC₅₀ IPC-81) for a wide variety of compounds including imidazolium, pyridinium, ammonium, phosphonium, pyrrolidinium and quinolinium ILs. S_σ-profile is a two-dimensional quantum-chem. parameter capable of characterizing the electronic structure and mol. size of cations and anions. By using a COSMO-RS descriptor for a training set of 105 compounds (96 ILs and 9 closely related salts) with known biol. activities (exptl. Log EC₅₀ IPC-81 values), a reliable neural network was designed for the systematic anal. of the influence of structural IL elements (cation side chain, head group, anion type and the presence of functional groups) on the cytotoxicity of ∼450 IL compounds The Quant. Structure-Activity Map (QSAM), a new concept developed here, was proposed as a valuable tool for (i) the mol. understanding of IL toxicity, by relating Log EC₅₀ IPC-81 parameters to the electronic structure of compounds given by quantum-chem. calculations; and (ii) the sustainable design of IL products with low toxicity, by linking the chem. structure of counterions to the predictions of IL cytotoxicity in handy contour plots. As a principal contribution, quantum-chem.-based QSAM guides allow the anal./quantification of the non-linear mixture effects of the toxicophores constituting the IL structures. Based on these favorable results, the QSAR model was applied to estimate IL cytotoxicities in order to screen com. available compounds with comparatively low toxicities.

These iodobismuthates display two types of structures: 1 contains a [BiI₆]^3- monometallic unit, and 2–4 possess binuclear [Bi₂I₉]^3- clusters, which are formed by two BiI₆ octahedra via face-sharing. The reactants BIP, TIP, and TIB were in situ transformed into [Me₃BIP]³⁺ in 1 and 2, [Me₃TIP]³⁺ in 3, and [Me₃TIB]³⁺ in 4 through the direct N-methylation reaction.
