摘要
Homogeneous synthesis of cellulose acetate was described.The pre-treated and activated cotton wool dissolved in mixtures of lithium chloride and N, N-dimethylacetamide(LiCl/DMAc),then react with acylating solvents. Compared to heterogeneous synthesis,it had many advanages:(1) reactions could be conducted at moderate temperatures;(2) less degradation of the cellulose occurs;and (3)substitution is uniformly controllable.
