Abstract
This invention relates to a method for preparing cellulose ester acetate from plant cellulose in ionic liquid. The method comprises: (1) utilizing plant cellulose as the raw material; (2) dissolving plant cellulose in ionic liquid; (3) adding acylation agent into the ionic liquid, performing homogeneous acetylation on plant cellulose, washing the intermediate with water and drying; (4) separating and purifying dried intermediate to obtain cellulose ester acetate. This invention provides a method for homogeneously preparing cellulose ester acetate in clean solvent (ionic liquid) by using low quality plant cellulose as the raw material. The method solves the problem of high cost faced by the present methods.
