The title mol-ecule, C20H20N2S2, is T-shaped and consists of a nearly flat 5,6-dimethyl-2-(5-methyl-thio-phen-2-yl)benzimidazole system approximately perpendicular to the 5-methyl-thio-phen-2-ylmethyl substituent. The 5,6-dimethyl-2-(5-meth-yl-thio-phen-2-yl)benzimidazole system is rotationally disordered about the two imidazole N atoms as approximated by a twofold rotation axis with a refined ...

the conversion of the cellulose into 5-hmf would experience three steps, cellulose to glycose, glycose to fructose and fructose to 5-hmf. chloride ion can break down the hydrogen bond in cellucose, chromium can catalyze the isomerization of glycose to fructose, and the high temperature is helpful to cyclohydration of fructose to 5-hmf. in this paper, the sawdust has been directly degraded into ...
