Catalytic activity of styrene/divinylbenzene copolymeric support immobilized with imidazolium ionic liquids in disproportionation of trichlorosilane was written by Petukhov, A. N.;Vorotyntsev, A. V.;Razov, E. N.;Nyuchev, A.;Makarov, D. A.;Vorotyntsev, V. M.. And the article was included in Journal of Physics: Conference Series in 2018.Formula: C4H7ClN2 This article mentions the following:
For the first time, imidazolium chloride-based ionic liquids (namely 1-methylimidazolium chloride and 1-butyl-3-methylimidazolium chloride) immobilized into macroporous styrene-divinylbenzene copolymer support (5-25 weight% of ionic liquid) were studied as catalysts for trichlorosilane disproportionation in the gas phase in the 293 – 393 K temperature range. In the case of the catalyst containing 15 weight% of the ionic liquid the apparent energy of activation was found to be 67.44 K and the reaction rate constant was found to be 0.2 s-1 at 393 K. This catalyst was found to be stable up to 408 K, further heating leads to thermal decomposition of the polymer matrix with chloroform as main gas product. The catalytic activity of the catalyst showed to be stable after 3 mo at 393 K. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Formula: C4H7ClN2).
1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Formula: C4H7ClN2
