摘要
用固液相转移催化法由氯乙酸和 2 ,4二氯苯酚合成 2 ,4二氯苯氧乙酸。研究了不同反应温度 ,催化剂对产率的影响。用聚乙二醇 ( PEG) 4 0 0和 KI双组分催化剂 ,得产率 92 %。
dichlorophenoxy acetic acid was synthesized by reaction of chloroacetic acid and 2,4dichlorophenol with solidliquid phase trasfer catalyst. Different temperature and catalyst on effect of yield have been studied. Using PEG400/KI for catalyst, the yield was 92%.
