【Abstract】 Preparation of chlorlacetic acid using 2-Naphtha and chloroacetic acid as materials in the basic condition was introduced in this paper. Influences of mole ratio and time on the reaction were studied. the optimal technology condition was obtained. The experiment proved that yield of production reached 65.48 % and purity was more than 98 %.更多还原
