摘要

以2,2'-亚甲基双(4-甲基-6-叔丁基苯酚) （简称抗氧剂2246）、丙酰氯为反应原料，三乙胺为缚酸剂，采用二氯甲烷为反应溶剂，直接合成2-(2-羟基-3-叔丁基-5-甲基苄基)-4-甲基-6-叔丁基苯基丙酸酯（简称抗氧剂3426）的方法。探讨了摩尔比n(抗氧剂2246):n(丙酰氯)、反应时间、反应温度对反应产率的影响，本合成方法绿色环保，溶剂可以循环使用，符合绿色化学理念。

Abstract:

This article discussed with 2, 2 '- methylene double (4 - methyl - 6 - tertiary butyl phenol) referred to as the antioxidants, （antioxidant 2246) reaction, propionyl chloride as raw materials, triethylamine as the bound acid agent, using dichloromethane as solvent, the direct synthesis of 2 - (2 - hydroxy - 3 - tert-butyl - 5 - methyl benzyl) - 4 - methyl - 6 - tert-butyl phenyl propionate (hereinafter referred to as antioxidant 3426) method.The effects of molar ratio n(antioxidant 2246):n(propionyl chloride), reaction time and reaction temperature on the yield were studied.The synthesis method is green and the solvent can be recycled, in line with the concept of green chemistry.

Key words: antioxidant 3426 propionyl chloride triethylamine
