Study on the alkylation of isobutane/butene in acidic ionic liquids was written by Liu, Ying;Hu, Rui-sheng;Liu, Gui-li;Xu, Chun-ming. And the article was included in Fenzi Cuihua in 2010.SDS of cas: 478935-29-4 The following contents are mentioned in the article:
The catalytic performance of acidic ionic liquids on the isobutane/butene alkylation was investigated. The acidic strength of ionic liquids has been improved by modified cation, anion and liquid acid. The amount of TMP in the [MBSIM]OTf alkylate can reach 69.8%. The reaction system can be used for 8 times without significant decrease in catalytic performance. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4SDS of cas: 478935-29-4).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. 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).SDS of cas: 478935-29-4
