2-氯苯氧乙酸的催化合成研究
Catalytic Synthesis of 2-Chlorophenoxyacetic Acid
摘要
Abstract
The use of cetyltrimethylammonium bromide catalyzed chloroacetate and 2-chlorophenol synthesis of 2-chlorophenoxyacetic acid. Cetyltrimethylammonium bromide has a higher catalytic activity and can accelerate the synthesis of 2-chlorophenoxyacetic acid. The reaction is studied on 2-chlorophenol and chloroacetic acid molar ratio,catalyst amount, reaction time and temperature on yield,and the performance of repeated use of catalyst. The best reaction conditions are as follows: at 85℃,2-chlorophenol and chloroacetate molar ratio of 1 : 4,catalyst weight of 0.3g,reaction time of 3.5h, which get 2-chlorophenoxyacetic acidproduction rate of 50.50 %. This catalyst is characterized by small amount, easy recovery,and can be reused.关键词
