| Abstract: | The synthesis of di(2 ethylhexyl)phthalate was performed by esterification of 2 ethylhexyl alcohol and phthalic anhydride in catalysis of p toluenesulfonic acid loaded on active carbon under microwave irradiation. The optimum reaction conditions were as follow:the ratio of phthalic anhydride to 2 ethylhexyl alcohol was 0.15g∶0.64ml,catalyst,microwave power,and microwave irradiation time were 0.6g,525W,and 55s respectively.The conversion rate of phthalic anhydride in the synthesis of DOP was up to 91.5%,the catalyst could be easily separated from reaction product,and used repeatedly. |
