摘　　要：环氧氯丙烷的生产方法有丙烯高温氯化法和醋酸丙烯酯法 2种 ,前者生产过程灵活 ,工艺成熟 ,操作稳定 ;后者反应条件温和 ,不产生盐酸副产物。环氧氯丙烷生产技术的发展动向是改进传统工艺技术和研发新技术。意大利埃尼化学公司开发的氯丙烯及其衍生物环氧化制备环氧氯丙烷新工艺以TS 1沸石为催化剂 ,反应温度为 4 5℃ ,反应时间 1h ,产物的选择性达到 99%。There are two methods for producing epichorohydrin i.e. prop yl ene chlorination under high temperature and propenyl acetate process, the former exhibits flexibility of process, mature technology, stability of operation, and the latter features mild reaction conditions and no by-product hydrochloric ac id formation. Improving the present process and development of new technology ar e the trends for developing of epichlorohydrin production. Based on epoxidation of chloropropylene and its derivatives developed by Italian ANIC Chemical Compa ny, using TS-1 zeolite as catalyst, under reaction temperature of 45℃ with rea ction time of 1h, the selectivity of title product can reach as high as 99%.
