Synthesis of Tetrakis-[3-(3, 5-Di-T-Butyl-4-Hydroxyphenyl)-Propionoyloxymethyl]Methane by a New One-Step Method Ⅱ. Studies on the Synthesis of Tetrakis-[3-(3,5-Di-T-TButyl-4-Hydroxypkenyl)-Propionoyloxymethyl] Methane

在１５升的不锈钢反应釜中，以２，６－二叔丁基苯酚，丙烯酸甲酯为原料，在叔丁醇钾催化剂存在下，对一步法合－（３－（３，５－二叔丁基－４－羟基苯基）丙酸）季戊四醇酯（抗氧剂１０１０）的酯交换反应工艺进行了研究，优化了反应条件，结果表明，在较佳的条件下，反应的选择性及收率分别达９２％，８３％，反应产物经结晶等后处理，抗氧剂１０１０产后质量及其应用效果与国外同类产品相当。

etrakis-[ 3-(3, 5-di-t-butyl-4-hydroxypheny )-propionyloxymethyl]-methane, a main antioxidant for ployene was synthesized by one step in a 15 liter stainless batch tank reactor. The optimum technological conditions were determined. Excellent yield and selectivity were obtained from parallel experiments.
