Ionic Liquid-Water Mixtures: Enhanced Kw for Efficient Cellulosic Biomass Conversion was written by Zhang, Yuetao;Du, Hongbo;Qian, Xianghong;Chen, Eugene Y.-X.. And the article was included in Energy & Fuels in 2010.Name: 1-ethyl-2,3-dimethylimidazolium chloride This article mentions the following:
Under relatively mild conditions (≤ 140°, 1 atm) and in the absence of added acid catalysts typically employed in biomass conversion, cellulose dissolved in certain ionic liquids (ILs) was converted into water-soluble reducing sugars in high total reducing sugar yield (up to 97%), or directly into the biomass platform chem. 5-hydroxymethyl furfural (HMF) in high conversion (up to 89%) when CrCl2 is added. The combined study of exptl. methods and ab initio calculations demonstrates that the significantly increased Kw by ILs in the IL-water mixture is responsible for the catalysis seen in the current efficient biomass conversion system without added acid catalysts. The finding that the water in ILs under mild conditions can exhibit high Kw values (up to 3 orders of magnitude higher than the pure water under ambient conditions) is significant because such high Kw values are typically achievable by the water under harsh high-temperature or subcritical water conditions. In the experiment, the researchers used many compounds, for example, 1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6Name: 1-ethyl-2,3-dimethylimidazolium chloride).
1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.Name: 1-ethyl-2,3-dimethylimidazolium chloride
