▎ 摘　　要

NOVELTY - Glycerol ester is prepared by reacting glycerol and acetic acid in the presence of sulfonated graphene catalyst at 70-140 degrees C and 0-2 MPa in which molar ratio glycerol:acetic acid is 1:1-1:50. USE - Preparation of glycerol ester by catalytic esterification (claimed). ADVANTAGE - The preparation has two-dimensional plane structure, provides space for macromolecular reaction, and obtains high secondary ester and tertiary ester selectivity.
