| Abstract: | Diethylene glycol dibenzoate （DEDB） was synthesized from benzoic acid and ethylene glycol usning self- made zinc itaconate as catalyst. The suitable reaction conditions for preparing DEDB were obtained as follows： the molar ratio of benzoic acid to ethylene glycol 2 ： 1.33 ,dosage of catalyst 3% （based on the mass of benzoic acid）, reaction time 5 hours, reaction temperature 125 - 130 ℃. Under the above reaction conditions, the product could be obtained with the yield up to 93.8% and good colority. The catalyst was easy to separate from product and could be repeatedly used. |
