摘要:
通过对乙酸在硫磺、乙酐和乙酰氯为催化剂下进行氯化制备氯乙酸反应机理的研究, 认为乙酰氯是反应体系中真正的催 化剂, 副反应属于连串反应, 并由此提出了抑制副反应发生的几种途径。
Abstract:
The Mechanism for Catalyzed Chlorination of Acetic Acid to mono -and dichloroacetic acids was studied .The result indicated that AcCl acts as the active catalyst and that dichloroacetic acid w as formed mainly via the chlo rination of acetyl chloride to dichloroacetyl chloride , w hich undergoes chlorine exchange to dichloroacetic acid .Several w ays for prohibit ing forming dichloroacetic acid (DCA)w as brought forth
