Synthesis of Br蠁nsted-Lewis acidic ionic liquids and their use as catalysts in rosin dimerization was written by Wang, Jin-long;You, Xing-lin;Fang, Yun. And the article was included in Jingxi Huagong in 2014.Recommanded Product: 35487-17-3 This article mentions the following:
A Br蠁nsted acidic ionic liquid mim 路 HCl was synthesized as an intermediate by protonating N-Me imidazole with Br蠁nsled acid donor hydrochloric acid. And a group of dual acidic ionic liquid 1-hydro-3-methylimidazole chloride chloroironinates (1-蠂) [mim 路 HCl] 蠂 [FeCl3] (where 蠂 is the mole fractions of the Lewis acid) was synthesized from the reaction of mim 路HCl and a Lewis acid donor FeCl3. The acidity of the group was characterized and compared to each other by means of FTIR in virtue of pyridine and acetonitrile mol. probe, resp. The dual acidic ionic liquids were then employed lo catalyze rosin dimerization. A dimeric rosin acid with a softening point of 102.4 degree C was obtained using (1-蠂) [mim路HCl]蠂[FeCl3] (蠂=0.64) as catalyst, which was 15 degree C higher than that without using catalyst. The catalytic activity became weaker after the fifth use. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Recommanded Product: 35487-17-3).
1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Recommanded Product: 35487-17-3
