摘要
采用活性炭固载钛酸四丁酯作催化剂合成了邻苯二甲酸二异辛酯（ＤＯＰ）．确定了合成的最佳工艺条件为：醇酐摩尔比２．８∶１，酯化温度２１０℃，酯化时间２．５ｈ，催化剂用量０．５％．在此条件下，产品ＤＯＰ酯化转化率≥９９．８％．结果表明，该催化剂催化活性好，后处理容易，可以重复使用，降低了成本，且无“三废”污染．
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.
