In this study, imidazolium based acidic ionic liquids and CrCl3·6H2O were used to catalyze the hydrolysis of cellulose in ionic liquid 1-allyl-3-methylimidazolium chloride ([Amim]Cl) via microwave-assisted irradiation to prepare 5-hydroxymethylfurfural (5-HMF). The effects of the type and amount of catalysts, reaction temperature and time, amount of water on the degradation of cellulose were studied in details. The results indicated that [C2mim]HSO4 and CrCl3·6H2O were efficient catalysts for preparing 5-HMF. The cellulose could be completely converted with the highest total reducing sugars (TRS) yield of 87.22% and 5-HMF yield of 50% under the condition of nMCC:nCr = 10:1, the mass of [C2mim]HSO4 = 0.02 g, and reaction temperature 160°C under microwave-assisted heating for 30 min. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4COA of Formula: C10H20N2O4S).
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).COA of Formula: C10H20N2O4S
