| Abstract: | The synthesis of dioctyl phthalate from phthalic anhydride and 2-ethyl hexanol over rare earth solid superacid SO_4~(2-)/TiO_2/Ce(Ⅳ)catalyst was studied.The influential factors on reaction were investigated.The results showed that the appropriate conditions were as follows:mole ratio of 2-ethyl hexanol to phthalic anhydride was 3∶1,the amount of catalyst was 1% of the weight of reactants,reaction temperature was 205℃,reaction time was 3 h.The yield of dioctyl phthalate may up to 97%. |
