【摘要】 用Ｈβ及不同方法制得的ＨＺＳＭ－５沸石作催化剂，对环己烯－水，环己烯—水－乙酸两种反应体系中的水合反应进行了研究。用ＧＣ－ＩＲ对产物进行了定性分析。用ＢＥＴ重量法测定了各种沸石对反应物的饱和吸附量。结果表明，在两种反应体系中，Ｈβ的催化活性显著地高于ＨＺＳＭ－５。ＧＣ－ＩＲ分析表明，在ＨＺＳＭ－５上，主要副产物是环己烯－［１］－酮－［３］和４－甲基环戊烯；在Ｈβ沸石上，主要副产物是２－环己烯基环己酮。对环己烯－水－乙酸体系由于乙酸的加入，不仅改善了反应物之间的互溶性，同时也改变了生成环己醇的途径，既提高了环己醇的产率，又得到高产率的乙酸环己酯。更多还原

【Abstract】 In the paper the catalytic properties of zeolites in the hydration reaction of cy-clohexene-water and cyclohexene-water-acetic acid were discussed. Several types of cata-lysts Hβ, HZSM-5 synthesized with, and without template compound were used. The mainby-products were identified by the method of GC-IR-The adsoptive capacity of the zeo-lites for the cyclohexene,water and acetic acid were determined by the BET method. It wasfound that the catalytic activity of the Hβ zeolite was obviously higher than HZSM-5in thetwo reaction systems, and the main by-products of hydration reaction of cyclohexene werecyclohexene-[1]一one-[3] and 4-methyl cyclopentene on the HZSM-5 zeolites, but 2-cy-clohexenyl cyclohexanone on the Hpzeolite. The high catalytic activity of Hβzeolite is causedby a larger size of aperture and adsorptive capacity for cyclohexene than HZSM-5. 2- cyclo-hexenyl cyclohexanone was not produced on the HZSM-5 since it has a smaller size of aper-ture than Hβ. When acetic acid was additived in the reaction system, the coinpatibility of thecvclohexene with water was enhanced and the selective adsorption of cyclohexene on zeoliteswas also increased.Therefore the formation of cyclohexyl carbonium ion was promoted.Onthe other hand,the additional reaction of the cyclohexene with acetic acid vvas easily carredout to give a large number of cyclohexyl acetate and its hydrolysis produced cyclohexanol.更多还原
