摘　　要：复合固体超强酸PO4 3- /Ti La O对DOP的合成有较高的催化活性 ,苯酐 3h的转化率超过 99% ,并找出了DOP合成的最佳条件 :辛醇 140mL、邻苯二甲酸酐 30g、催化剂 4g、活性炭 0 .2g、反应时间 4h .该催化剂具有耐水性强、可重复使用、再生容易、不污染环境等优点 .The composite solid superacid PO 4 3- /Ti La O has high catalytic activity on the synthesis of DOP. The conversion of phthalic anhydride is not less than 99% after three hours. The conditions of synthesis of DOP have been studied: the octanol is 140ml, the phthalic anhydride is 30g, the quantity of catalyst is 1.0g, the absorbite is 0.2g, the time of reaction is 4h. The best technology condition has been found. This kind of solid superacid has many advantages, such as being able to use several, recovery very easy, high water resistibility, less corrosion for the equipment and less pollution to the environment.
