Effectively catalytic hydrolysis of cellulose to glucose in the presence of pyrrolidonium-based acidic ionic liquids was written by Feng, Jianping;Liu, Min;Jia, Songyan;Gong, Yanyan;Song, Chunshan;Guo, Xinwen. And the article was included in Shiyou Xuebao, Shiyou Jiagong in 2012.Name: 1-Methyl-1H-imidazol-3-ium chloride This article mentions the following:
A series of acidic ionic liquids (methylimidazolium-based acidic ionic liquids and pyrrolidonium-based acidic ionic liquids) were synthesized and characterized. The cellulose hydrolysis into glucose, in which ionic liquid 1-butyl-3-methylimidazolium ([Bmim]Cl) was used as the solvent, in the presence of the synthesized acidic ionic liquids was studied systematically. The influences of water content, procedure of adding water, kinds of catalyst, catalyst dosage, reaction temperature and reaction time on the conversion of cellulose and yield of glucose were investigated. It was shown that pyrrolidonium-based acidic ionic liquids were better in catalyzing the hydrolysis of cellulose into glucose than methylimidazolium-based acidic ionic liquids Under the optimized reaction conditions, which were the reaction temperature of 110掳C, n(catalyst): (glucose unit in cellulose): n(H2O) = 1:3:210, [Hnmp]CH3SO3 as catalyst, with the water addition of once per 10 min in 40 min, and the reaction time of 2 h, the glucose yield of cellulose hydrolysis was 68%. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Name: 1-Methyl-1H-imidazol-3-ium chloride).
1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. 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).Name: 1-Methyl-1H-imidazol-3-ium chloride
