摘要
对由3,5-二叔丁基-4羟基苯丙酸甲酯(简称3,5-甲酯)与季戊四醇进行酯交换反应合成四-[3-(3,5-二叔丁基-4-羟基苯基)丙酸]季戊四醇酯(简称抗氧剂1010)的工艺条件进行了研究,分析了催化剂加入量、反应物配比、反应温度及反应时间等因素对酯交换反应的影响,优化了工艺条件。结果表明,新工艺条件下生产的抗氧剂1010产品质量为优级品。
The process conditions of synthesizing tet-rakis -[3-(3,5 -di - tert - butyl - 4 - hydroxyphenyl) -propionyloxymethyl] methane by transesterification reaction of methyl - (3,5 - di- tert - butyl - 4 - hydroxyphenyl) pro-pionate and pentaerythritol are studied. The influences of re-actants ratio, additional quantity of the catalyst, reaction temperature and reaction time on the transesterification reaction are analyzed. The technological conditions are optimized and the superior products are obtained.
