Two multi-component crystal structures comprising a carboxylic acid-functionalized imidazolium zwitterion, a p-sulfonatocalix[4]arene anion and aquated metal ion (Na+ or Y3+) with or without an auxiliary component (the 3-methoxyphenyl-triphenylphosphonium cation) are reported. The carboxylic acid-functionalized imidazolium ion binds either as a monodentate or a bidentate ligand depending on the nature of the metal ions, and a bi-layer arrangement prevails in the extended structure regardless of the type of metal ion employed or presence/lack of auxiliary component.

A method was developed for the synthesis of isoxazoles such as I [R1 = H, Me, 4-BrC6H4, etc.; R2 = Pr, cyclopentyl, 4-MeC6H4, etc.; R3 = H, Br, n-Pr, etc.; X = CH2, O; n = 1, 2, 3, 4, 5] via palladium-catalyzed ionic liquid-accelerated oxidative cascade annulation/functionalization of acetylenic oximes with unactivated long chain enols/allylic alcs. under aerobic conditions. This newly developed protocol provides the rapid and straightforward synthetic strategy for the assembly of structurally diverse isoxazole architectures under mild conditions with high atom- and step-economy and exceptional functional group tolerance. Notably, the ionic liquid acts as not only a solvent in the reaction but also provided the excess halide ions to eliminate hydrochloride from acetylenic oximes. Moreover, this catalytic system could be recycled up to eight times and reused without significant loss of the catalytic activity.

Excessive CO2 emissions have resulted in global warming and are a serious threat to the life of people, various strategies have been implemented to cut carbon emissions, and one of them is the use of a gas separation membrane to capture CO2 effectively. In this experiment, the butadiene-bridged polymethylsiloxane (BBPMS)/ethyl cellulose (EC)/ionic liquid (IL) ternary composite membranes were prepared by EC as a substrate, BBPMS, and IL as additives in THF under high-speed stirring and coated on the membrane. The membrane structure was characterized by a Fourier transform IR spectrometer and scanning electron microscope, and the membrane properties were tested by a membrane tensile strength tester, thermal weight loss analyzer, and gas permeability meter. The results show that the surface of the ternary composite membrane is dense and flat with a uniform distribution, and the membrane formation, heat resistance, and mech. properties are good. The permeability coefficient of the ternary composite membrane for CO2 reached 1806.03 Barrer, which is 20.00 times higher than that of the EC/IL hybrid matrix membrane. The permeability coefficient of O2 reached 321.01 Barrer, which is 19.21 times higher than that of the EC/IL membrane. When the doping amount of BBPMS is 70-80%, the O2/N2 gas permeation separation of the BBPMS/EC/IL ternary composite membrane is close to the Robertson 2008 curve. It is always known that in the gas separation process the membrane material is the most crucial factor. The success of this experiment points to a new direction for the preparation of new membrane materials.

Porous uranium oxide hollow sphere nanoparticles were synthesized in ionic liquids under hydrothermal conditions. Various precipitating agents and ionic liquids were investigated to determine their resp. impact on the resultant uranium oxide morphologies. Using hydrazine hydrate as precipitating agent and N-Bu pyridinium bromide as templating agent, a porous-hollow structure was created with a surface area of 1958 m2.g-1 and an average pore diameter of 30 nm. The nanoparticles revealed high peroxidase-mimicking activity. This was evaluated by using the peroxidase substrate 3,3′,5,5′-tetramethylbenzidine (TMB) that is catalytically oxidized by H2O2 to give oxidized TMB (oxTMB) which is blue (with an absorption peak at 652 nm). The material was used as a nanozyme for colorimetric detection of Sn2+. Meanwhile, it is found that BSA strongly improves the catalytic activity of the nanozyme, while Sn(II) inhibits its activity. Thus, a colorimetric method for Sn2+ detection was designed. The method works in the 0.5-100μM Sn(II) concentration range and has a lower detection limit of 0.36μM (at S/N = 3).

Moraes, Carolina V.; Demetrio da Silva, Vinicius; Castegnaro, Marcus V.; Morais, Jonder; Schrekker, Henri S.; Amico, Sandro C. published the artcile< Lightweight Composites through Imidazolium Ionic Liquid Enhanced Aramid-Epoxy Resin Interactions>, Product Details of C6H9ClN2O2, the main research area is lightweight composite imidazolium ionic liquid aramid epoxy resin.

Poly(p-phenylene terephthalamide) (PPTA) is mostly used as a low-d. polymeric fiber with high specific stiffness and strength, and thermal and chem. stability. The fiber is used as a reinforcement in composite materials in the aerospace and automobile industries, as well as in ballistic and stab-resistant articles. However, its use in composite materials is hampered by its low interfacial affinity with polymeric matrixes due to its smooth and inert surface. To overcome such low interfacial interaction, various treatments have been applied to modify the aramid surface. However, it is still challenging to identify an industrially feasible process that does not neg. impact mech. properties of the aramid fibers. The objective of this study was to investigate different ionic liquids (ILs) with suitable chem. structures as alternative compatibilizers for aramid fibers with epoxy resin. Kevlar fibers were submitted to ethanolic solutions of imidazolium IL (1-n-butyl-3-methylimidazolium chloride, 1-carboxymethyl-3-methylimidazolium chloride, 1-triethyleneglycol monomethyl ether-3-methylimidazolium methanesulfonate, or 1-n-butyl-3-methylimidazolium methanesulfonate) and then analyzed by IR spectroscopy, thermogravimetry, SEM, and XPS. Fiber tensile tests, pull-out tests, and contact angle measurements were used to characterize the fiber and its interface with the epoxy resin. Treatment with all IL, except 1-carboxymethyl-3-methylimidazolium chloride, enhanced the wettability and adhesion of the fibers without imparing mech. properties. Epoxy resin-based composites were produced using com. fabrics before and after 1-triethyleneglycol monomethyl ether-3-methylimidazolium methanesulfonate treatment and characterized via tensile and short-beam tests. The composite produced with treated fabrics presented slightly higher tensile strength, modulus, and interfacial shear strength, which can be of interest to the composite sector.

Kerche, Eduardo Fischer; da Silva, Vinicius Demetrio; da Silveira Jankee, Gabriela; Schrekker, Henri Stephan; de Avila Delucis, Rafael; Irulappasamy, Siva; Amico, Sandro Campos published the artcile< Aramid pulp treated with imidazolium ionic liquids as a filler in rigid polyurethane bio-foams>, Reference of 700370-07-6, the main research area is aramid pulp imidazolium ionic liquid filler polyurethane biofoam.

This article reports an aramid pulp (AP) treated with two ionic liquids (IL), namely 1-n-butyl-3-methylimidazolium chloride (C4.Cl) and 1-carboxymethyl-3-methylimidazolium chloride (HO2C), and its use as a filler in reinforced rigid polyurethane foams (RPUF). The RPUF were incorporated with the treated AP at three weight fractions (c.a. 0.1, 0.5, and 1.0 wt%) and were produced by the free rising method. The results showed that the studied IL promoted a better interaction between the AP and the RPUF system, which increased the overall reactivity, imparting a higher cell anisotropy. This also yielded a pos. effect in mech. properties and thermal stability of the RPUF. Compared to the neat RPUF, outstanding increases of approx. 50 and 20% were achieved in compressive modulus and strength, resp. In all, the use of IL promoted increased compatibility between matrix and reinforcement, especially that HO2C IL.

Fonseca, E.; Demetrio da Silva, V.; Klitzke, J. S.; Schrekker, H. S.; Amico, S. C. published the artcile< Imidazolium ionic liquids as fracture toughening agents in DGEBA-TETA epoxy resin>, Formula: C6H9ClN2O2, the main research area is epoxy resin imidazolium ionic liquid mech thermal property.

Although epoxy resins are used in a broad variety of applications due to their good mech. and thermal properties, their low fracture toughness is a limitation, exhibiting brittle behavior. This study explored the potential use of imidazolium ionic liquids (IL) as toughening agents for epoxy resin based on diglycidyl ether of bisphenol A (DGEBA) with triethylenetetramine (TETA) as curing agent. Fracture toughness was evaluated for DGEBA-TETA epoxy resins with eleven imidazolium IL and the best results were found for the IL with the chloride anion and the shortest N-alkyl side chain, C4MImCl. The use of 1.0 phr of C4MImCl lead to the reduction of the crosslink d. of the post-cured resin, resulting in the increase of 25.5% in stress intensity factor and 8.2% in tensile strength with no significant loss in other mech. properties.

Salvitti, Chiara; Pepi, Federico; Manago, Marta; Bortolami, Martina; Michenzi, Cinzia; Chiarotto, Isabella; Troiani, Anna; de Petris, Giulia published the artcile< Free N-heterocyclic carbenes from Bronsted acidic ionic liquids: Direct detection by electrospray ionization mass spectrometry>, Related Products of 700370-07-6, the main research area is methyl carboxymethylimidazolium chloride ionic liquid preparation zwitterion.

The occurrence of N-heterocyclic carbenes in imidazolium-based ionic liquids has long been discussed, but no spectroscopic evidence has been reported yet due to their transient nature. The insertion of an ionizable acid group into the cation scaffold of an ionic liquid which acts as a charge tag allows for the direct detection of free carbenes by mass spectrometry. Three different Broensted acidic ionic liquids were synthesized: 1-methyl-3-carboxymethylimidazolium chloride (MAICl), 1-methyl-3-carboxymethylimidazolium acetate (MAIAc) and the corresponding 2-(3-methyl-1H-imidazol-3-ium-1-yl)acetate zwitterion (MAI – H). The speciation of these compounds was then analyzed by electrospray ionization ion-trap mass spectrometry in the neg. ion mode. The C2-H deprotonation of the imidazolium cation leading to the formation of the corresponding carbene is highly affected by the basic properties of the counter-anion. In the case of MAICl and MAI – H ionic liquids, no charged species corresponding to the free N-heterocyclic carbene was detected. On the contrary, in the presence of a sufficiently basic anion, such as acetate of MAIAc ionic liquid, an intense signal related to the free carbenic species was observed without the addition of an external base. In situ formation of free N-heterocyclic carbenes from Broensted acidic ionic liquids was demonstrated, highlighting the crucial role of anion basicity in promoting the C2-H proton abstraction from imidazolium cations with a carboxylic side chain.

Et cellulose was grafted with ionic liquids in optimal yields (62.5-64.1%) and grafting degrees (5.93-7.90%) by the esterification of the hydroxyl groups in Et cellulose with the carboxyl groups in ionic liquids In IR spectra of the Et cellulose derivatives exhibited C = O bond stretching vibration peaks at 1760 or 1740 cm-1, confirming the formation of the ester groups and furnishing the evidence of the successful grafting of Et cellulose with ionic liquids The Et cellulose grafted with ionic liquids could be formed into membranes by using the casting solution method. The resulting membranes exhibited good membrane forming ability and mech. properties. The EC grafted with ionic liquids-based membranes demonstrated PCO2/PCH4 separation factors of up to 18.8, whereas the PCO2/PCH4 separation factor of 9.0 was obtained for pure EC membrane (both for CO2/CH4 mixture gas). The membranes also demonstrated an excellent gas permeability coefficient PCO2, up to 199 Barrer, which was higher than pure EC (PCO2 = 46.8 Barrer). Therefore, it can be concluded that the ionic liquids with imidazole groups are immensely useful for improving the gas separation performances of EC membranes.
