PROCESS FOR PREPARING CELLULOSE ESTERS BY USE OF CARBOXYLIC ACIDS

摘要

Process for reducing the degree of substitution of cellulose esters employing carboxylic acids as solvolysis promoters is disclosed. Exemplary cellulose esters are cellulose acetate, cellulose propionate, cellulose butyrate, cellulose acetate propionate, and cellulose acetate butyrate.
