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
