目前 ,氯乙酸工业化的生产方法有硫酸水解法、氯乙酰氯水解法和乙酸氯化法３种。其中 ,氯乙酰氯水解联产其他下游产品在我国并不适宜。由硫酸水解三氯乙烯 ,可生产高纯度氯乙酸 ,此法消耗定额偏高 ,但为欧洲各国所采用。我国主要采用乙酸氯化法 ,在美国、加拿大等国也普遍采用 At present, the industrial production of chloroacetic acid sulfuric acid hydrolysis, chloroacetyl chloride hydrolysis and acetic acid chloride three. Among them, chloroacetyl chloride hydrolyzed co-production of other downstream products is not suitable in our country. Hydrolysis of trichlorethylene from sulfuric acid, can produce high-purity chloroacetic acid, high consumption of this method fixed high, but for the European countries adopted. China mainly acetic acid chloride method, in the United States, Canada and other countries are also commonly used
