我国第一套万吨级醋酐法氯乙酸装置,在无锡化工集团公司投入全面运行。长期以来,我国的氯乙酸生产大都采用硫磺法生产工艺,存在着环境污染严重,能源消耗过高,劳动强度大和产品杂质多等缺陷.在国内著名科研单位的大力支持下,无锡化工集团公司消化、吸收引进技术,于1999年上半年建成了我国第一套年产5000吨醋酐法氯乙酸生产装置,由于工艺技 China’s first 10,000-ton acetic anhydride chloroacetic acid plant was put into full operation in the Wuxi Chemical Group Corporation. For a long time, most of the chloroacetic acid production in China adopts the sulfur production process. There are serious environmental pollution, high energy consumption, high labor intensity and many product impurities. With the strong support of well-known research institutes in China, Wuxi Chemical Industry Group has digested it. In the first half of 1999, China’s first production plant for acetic anhydride chloroacetic acid with an annual production capacity of 5,000 tons was established.
