无锡代工集团公司引进吸收先进技术,并在科研单位的协助下,建成了年产50000吨醋酐法氯乙酸生产装置,并生产出合格产品。氯乙酸是一种重要的精细化工产品,广泛用于医药、染料、农药等产品的有机合成。长期以来,我国氯乙酸生产大都采用硫磺法,存在“三废”严重、能耗高、劳动强度大和产品杂质多等缺陷。无锡化工集团公司采用以醋酐为催化剂,氯化、结晶等工艺过程均与国际先进水平同步。产品中氯乙
Wuxi Foundry Group Corporation has introduced and absorbed advanced technologies, and with the assistance of scientific research units, it has built an annual production capacity of 50,000 tons of acetic anhydride chloroacetic acid production equipment and produced qualified products. Chloroacetic acid is an important fine chemical product widely used in the organic synthesis of pharmaceuticals, dyes, pesticides and other products. For a long time, most of the chloroacetic acid production in China has adopted the sulfur method, there are serious defects such as “three wastes”, high energy consumption, labor intensity, and many product impurities. Wuxi Chemical Group adopts acetic anhydride as a catalyst, and the chlorination and crystallization processes are synchronized with the international advanced level. Chlorine B in the product
