Abstract:
Cellulose acetate butyrates (CAB) were homogeneously synthesized in an ionic liquid, 1-allyl-3-methyl-imidazolium chloride (AmimC1).By a sequence of first adding butyric anhydride and then acetic anhydride in the cellulose/AmimCl solutions, CAB products with the butyryl contents ranging from 33% to 47%(mass) were obtained.NMR analysis showed that among the three OH groups of the anhydroglucose unit (AGU) of the synthesized CAB, the distribution of the butyryl moieties showed a preference at the C6 position, while the partial degree of substitution of acetyl moieties at the C6 position showed the minimum values.Solubility measurement showed that CAB samples readily dissolved in the common organic solvents, such as methyl ethyl ketone, dichloromethane, and ethyl acetate.
