摘　　要：Ｔｉ－Ｓｉ沸石的催化氧化性能Ⅱ．环己醇的氧化及环己酮的肟化夏清华，王公慰，应慕良，郑禄彬（中国科学院大连化学物理研究所，大连１１６０１２）关键词Ｔｉ－Ｓｉ沸石催化剂，Ｈ_２Ｏ_２氧化剂，环己醇氧化，环己酮肟化．１．前言环己酮肟是生产ε－己内酰胺的关键中...The oxidation of cyclohexanol by aqueous hydrogen peroxide(30 wt%)have been studied. It was observed that the oxidized product was only cyclohexanone and product yield increased with prolonging reaction time and lifting up reaction temperature.The preferred solvent was tert-butyl alcohol,Furthermore, it was also found that for the ammoximation of cyclohexanone and ammonia on TS-1 zeolites hydrogen peroxide possessed high catalytic activity. In three tested catalysts, conversion ratio of cyclohexanone and selectivity of oxime on TS─1 zeolite were the highest. When tert-butyl alcohol was used as the solvent, the yield of oxime could reach 38.5%(mol%).
