preparation | 1. add HZSM-5/MCM-41(1.5g) glycerol (0.15 mol) and acetic acid (1.20 mol) to a distillation column equipped with a mechanical stirrer, thermometer and distillation. 2. Continuously remove the water formed in the reaction process to move the chemical balance forward. 3. The esterification process was monitored by analyzing the products by gas chromatography using a flame ionization detector (FID) equipped with a SE-30 capillary column. |
