【摘要】 本文通过簿层层析法对钛酸酯偶联剂合成进行跟踪。找到了几种对原合成方法修改的实验方案。经过筛选,分批加料法,边反应边蒸出异丙醇法、二元恒沸法等对降低副产品提高钛酸酯偶联剂含量是有效的,特别是边反应边蒸出异丙醇法效果更佳。以三-肉豆寇酰氧基钛酸异丙酯偶联剂的合成为例,产品中混有的副产品羧酸酯的含量可降低到20.7%,酸的含量可降低到61.53%。更多还原

【Abstract】 The tracing of the synthesis of titanatecoupling agent was made by thin layerchromatograph. Based on the old method,some modified experimental methods wereachieved, and by a sieve method, some ofthe methods by which the by-products couldbe reduced and the content of the titanatecoupling agent could be raised wereproved to be efficient, and the results of thestudy were a1so given in this paper.更多还原
