| Abstract: | Ferric sulfate was used as the catalyst for esterification of acetic acid with glycol diacetate. Influence of glycol/acetic acid molar ratio, dosage of catalyst, reaction time and temperature on conversion of the esterification reaction was investigated. Experiment showed that ferric sulfate catalyst is featured by higher activity, ease in separation and simplicity in operation. Use of the catalyst instead of strong acids eliminates neutralization, washing and drying steps which are neccessary when using strong acids. |
