Cellulose acetates with low degree of substituent(DS) were homogeneously synthesized in an Ionic liquid, 1-allyl-3-methyl-imidazolium chloride (AmimCl). Under mild reaction conditions, cellulose monoacetates(CMA) with the DS in a range from 0.34 to 1.60 were obtained. NMR analysis shows that the distribution of acetyl moieties among the three OH groups of anhydroglucose unit is C6>>C3 > C2 for the synthesized CMA. The water solubility measurement shows that the CMA samples with the DS ranging… Expand
