摘要
β ( 3,5 二叔丁基 4 羟基苯基 )丙酰肼是制备双 [β ( 3,5 二叔丁基 4 羟基苯基 )丙酰 ]肼的重要中间产物 ,此化合物的制备方法已有介绍[1～ 3 ] .但该合成方法具有时间长、所得产品产率低、不易从体系中分离等缺点 .本实验在上述方法基础上进行了改进 ,使反应时间缩短了四分之一 ,并且产率达到了 96 % ,同时 ,在溶剂等方面的选择上使成本降低 。
di t butyl 4 hydroxyphenyl) propionyl hydrazide is an improtant intermediate product in synthesizing N,N' bis β (3,5 di t butyl 4 hydroxyphenyl) propionyl hydrazine.The compound are obtained by reacting methyl β (3,5 di t butyl 4 hydroxyphenyl)propionate with hydrazine hydrate. The preparation method of the compound has been introduced in U.S. Patent 3773722.But the yield of the product by this method is lower and the product is uneasy to be divided. This experiment improves the method to raise the yield and to cut down the cost.
