| Abstract: | The synthetic processes of phthalic anhydride diglycol ester using sulfuric acid and methyl benzene sulfonic acid as catalysts, respectively, were investigated. The results showed that the selectivity of the goal product using methyl benzene sulfonic acid as the catalyst was higher.The optimum condition of synthesizing phthalic anhydride diglycol ester was obtained as follows: methyl benzene sulfonic acid as catalyst, catalyst dosage=3%(mass fraction) of diglycol, reaction temperature 185 ℃, phthalic anhydride to diglycol molar ratio 1∶2, reaction time 10 h. The product purity was more than 98.0% under the optimum condition. |
