摘要： 用固-液相转移催化法合成了对-氯苯氧乙酸。研究了不同投料比、催化剂、反应温度对产率的影响,用PEG 800和KI双组分催化剂,制得对-氯苯氧乙酸,产率94.8%.

关键词: 对－氯苯氧乙酸, 相转移催化法, 合成

Abstract: p-Chlorophenoxy acetic acid was prepared by reaction of chloroacetic acid and p-chlorophenol in the presence of polyethylene glycoI PEG800 and KI with powdery K2CO3 in toluene. When the reaction was carried out at 105～110 ℃for 2 hours, the yield of p-chlorophenoxy acetic acid was 94.8%.

Key words: p-chlorophenoxy acetic acid, phase transfer catalysis, preparation
