| Abstract: | A method for synthesis of phthalic acid C_8～C_(10) ester based on the mixture of stannous oxide and tetrabutyl titanate as catalyst was developed.The influence factors of temperature, mole ratio of alcohol to acid, reaction time and catalyst weight were examined through orthogonal experiments. The best condition are as follows: temperature is 230℃,mole ratio is 2.5,weight of catalyst is 4‰ phthalic anhydride,reaction time is 3.0 h,under the optimum condition,the yield may reach 98.7%. |
