| Abstract: | The composite solid superacid SO 4 2- /Ti La O has high catalytic activity on the synthesis of DOP. The conversion of phthalic anhydride is not less than 99% after two hours. The conditions of synthesis of DOP have been studied. The best technology condition has been found: the quantity of catalyst is 1.0g, the ratio of octanol and phthalic anhydride is 3.0:1, the time of reaction is 2.5h. 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. |
