摘要
2氯丙酸是合成农药、染料和农林化学品的重要原料,最常用的制备方法是在硫磺和黄磷等催化剂的存在下,使用氯气对丙酸直接进行氯化。我国的生产厂家有常州大进化工科技有限公司、北京北化精细化学品有限公司、上海康晟实业有限公司和湖北百科药业股份有限公司等,日本只有大赛珞化学公司生产。目前世界上对苯氧基丙酸系细叶杂草除草剂的研究相当多,有望成为今后的研发趋势。
2-Chloropropionic acid is an important raw material for production of pesticides, dyestuffs and agro- and forest chemicals. In the presence of sulphur and phosphor, direct chlorination of propionic acid by chlorine is the common method for preparation of 2-chloro propionic acid. In China, the main producers of 2-chloropropionic acid are Changzhou Dajin Chemical Science & Technology Co., Ltd., Beijing Beihua Fine Chemical Co., Ltd., Shanghai Kangsheng Industry Group and Hubei Biocause Pharmaceutical Co., Ltd. While there is only one producer, Daicel Chemical Industry Company, in Japan. At present, there are lots of research works on herbicide based on phenoxypropionic acid in the world, it would be a promising development trend in the future.
