摘要
以活性炭担载对甲苯磺酸作催化剂，采用微波辐射技术，苯酐和异辛醇直接酯化合成邻苯二甲酸二异辛酯。最佳反应条件为：苯酐和异辛醇的配比为０．１５ｇ∶０．６４ｍｌ，催化剂０６ｇ，微波功率５２５Ｗ，微波辐射时间５５ｓ，转化率９１５％。催化剂易分离，且可重复使用。
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.
