Cellulose acetates with low degree of substituent(DS) were homogeneously synthesized in an ionic liquid,1-allyl-3-methyl-imidazolium chloride(AmimC1).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 distribu...
