【摘要】 <正> 高分子催化剂以其独特的优点和功能日益受到人们的重视,目前均相催化剂的高分子固载化已成为催化剂研究的一个新领域。烷基钛酸酯是合成高沸点酯的有效催化剂,具有催化活性高、不易引起副反应等优点,但由于是均相催化反应,催化剂不易分离且不能回收及重复使用。本文首次将钛酸四丁酯与聚苯乙烯二乙醇胺树脂及异辛醇反应,制成一种稳定性良好的高分子键联螯合钛酸酯催化剂,对合成邻苯二甲酸二辛酯(DOP)具有良好的催化活性,且可重复使用。更多还原

【Abstract】 : In this paper, a polymer-bonded chelated titanate was prepared by linking. The titanate can be. used to catalyze the esterification with a high yield, such as the preparation of di(2-ethylhexyl) ph-thalate, and can be reused 4 or 5 times. In addition, the relation between the structure of catalyst and the catalytic activity was also discussed.更多还原
