| Abstract: | ctivated carbon supported Ti(OBu)4 catalyst was prepared and used in catalytic synthesis of di(2ethylhexyl) phthalate (DOP). The best technology parameters were obtained:the molar ratio of 2ethylhexyl alcohol to diphthalate is 2.81,reaction temperature is 210,reaction time is 2.5 h,the amount of catalyst is 0.5%.The transformation of the product reaches 99.8%.The results showed that this catalyst had higher catalytic activity for esterification, made simplicity in treating the products and could be reused,the production costs could be reduce and without the three wastes. |
