| Abstract: | The chloroacetic acid was synthesized by acetic acid in this experiment, in which using thionylchloride as the catalyst,at the same time the chlorine and oxgen were added in as the chlorinating agents.The effect of reaction temperature and time, the amount and species of catalyst were investigated on the yield of product.The optional conditions were proved to be at temperature of 110℃, n(acetic acid):n(thionylchloride)=2:1, the highest yield up to 96.5% and the purity reached 99.5%. |
