摘　　要：在常压和较低的温度下,系统地研究了均相、非均相和固载型杂多酸(盐)催化剂在合成 DOP 中的催化作用,实验表明在合成 DOP 的酯化反应中,杂多酸(盐)具有很高的催化活性和选择性,首次将不饱和系列杂多酸催化剂应用于酯化反应。催化剂连续使用12次未见活性明显降低,DOP 催化属体型和表型反应的叠加。The catatysis of heteropty acids(Salts)in synthesizing dinoctylphthalates (DOP)has been studied at low temperature and atmospheric pressure.Itis found that heteropoly acids(Salts)possess high activity and selectivity in the reaction of esterifica- tion The activity of the catalysts is under pressed after continuously using twelve times. It is concluded that the catalyeic reaction is the overlap of the bodyand surface—reac- tions.
