氯乙酸装置系统的改造

摘要

通过对硫磺催化氯化制取氯乙酸工艺存在问题的分析、说明了淘汰该工艺的必要性。实施醋酐催化氯化工艺制取氯乙酸改造以后,带来了良好的经济效益和社会效益。%Through analyzed the problems of chloroacetic acid production process by sulfur catalyst, the necessity of the process which must be eliminated was elaborated.After the sulfur catalyst was replaced with acetic anhydride, the economic and social benefits were better.
