Abstract
Cellulose benzoate propionates (CBzP) were prepared via a staged addition of Pr2O followed by Bz2O to cellulose dissolved in tributylmethylammonium dimethyl phosphate (TBMADMP) providing regioselectively substituted cellulose esters in which the benzoate was preferentially installed at C2 and C3. By systematically varying the DSPr, DSBz, and DSOH (DS = degree of substitution), we synthesized CBzP that could potentially be utilized as a unique compensation film in optical displays.Entities:
