AbstractConversion of lignocellulose into useful chemicals is an important research topic in the area of biomass utilization. In this study, microcrystalline cellulose (MC) was dissolved in a mixed-solvent system containing the ionic liquid (IL) 1-allyl-3-methylimidazolium chloride ([Amim]Cl) andN-methyl-pyrrolidone (NMP), and the cellulose was directly converted into methyl glucoside (MG) by acid-catalyzed methanolysis aided by microwave irradiation (μWIr). Under moderate reaction temperature and pressure, and in the presence of acetyl chloride/methanol (in situformed HCl) as an acid catalyst, MG was obtained in a 42% yield. In contrast, in the absence of either IL or μWIr, the MG yield was only 5 or 21%, respectively. Both μWIr and the dissolution of cellulose in IL were quite effective for the conversion of cellulose into MG.

Reaction Media

In order to identify the best possible reaction media for performing H2S conversion, a total number of 300 different ILs from a combination of 20 cations and 15 anions were screened via COSMO-RS model simulations. By COSMO-RS method, thermodynamic and physicochemical properties of 300 ILs such as Henry’s law constants, activity coefficient, selectivity, capacity and performance index are obtained and analyzed. Thus, by comparing the performance of ILs via COSMO-RS, a series of TSILs containing cation of [P66614] with metal chloride anions such as Fe, Ga and Sn were chosen and selected for synthesis based on their performance predicted by COSMO-RS and their economic values. Consequently, the physiochemical properties such as density, viscosity, thermal properties, as well as H2S absorptive oxidation performances in those TSILs will be systematically investigated.

Modified mordenites have been used in the direct conversion of glucose into 5-hydroxymethylfurfural (5-HMF) in two different media: the ionic liquid 1-butyl-3-methylimidazolium bromide ([BMIM]Br) and a biphasic system composed of water–acetone and ethyl acetate.
