| 摘 要： | 分析乙酸在光、硫磺和醋酐催化条件下生成氯乙酸的反应机理.乙酸光催化反应速度快,但二氯乙酸生成量高.硫磺催化和醋酐催化产生的乙酰氯是真正的乙酸氯化催化剂.对二氯乙酸生成机理进行评述,认为乙酸氯化生成二氯乙酸属于平行-连串反应机理.

| Abstract: | The mechanism of chlorination of acetic acid catalyzed by light, sulfur and acetic anhydride for chloroacetic acid is analyzed. It is found that the rate of photo-chlorination of acetic acid is faster than that of catalytic chlorination in the presence of acetic anhydride or sulfur. And the amount of dichloroacetic acid is higher when the photo-catalysis is used. The acetyl chloride catalyzed by sulfur or acetic anhydride acts as the real catalyst for chlorination of acetic acid. The mechanism for synthesis of dichloroacetic acid is reviewed. It is suggested that the synthesis of dichloroacetic acid belongs to consecutive-parallel reaction. |
