氯乙酰氯是一种重要有机合成中间体。由于反应活性高，作为酰化剂在合成产品的收率和质量方面比其他酰化方法具有更大的优越性，在医药、农药、染料、溶剂、助剂等行业中应用日趋广泛，其消费量为氯乙酰氯总产量的70％。 合成氯乙酰氯的方法较多，国外通常采用乙烯酮氯化法
Chloroacetyl chloride is an important organic synthesis intermediate. Due to its high reactivity, acylation agents have greater advantages over other acylation methods in terms of yield and quality of synthetic products, and are increasingly used in medicine, pesticides, dyes, solvents, auxiliaries, and other industries. The amount is 70% of the total chloroacetyl chloride production. There are many methods for synthesizing chloroacetyl chloride, and ketene chloride is generally used abroad.
