摘要
综述了三氯化铁、硫酸铁、硫酸铁铵、硫酸铜、氧化亚锡、铌酸、PVC SO3H、聚氯乙烯 三氯化铁、D61和D72离子交换树脂、维生素C、固体超强酸TiO2/SO42 、活性炭固载的磷钨酸、硅钨酸、固载杂多酸盐TiSiW12O40/TiO2、HY型分子筛、改性HZSM 5分子筛及Fe ZSM 5分子筛等18种不同催化剂催化合成环己酮1,2 丙二醇缩酮的实验结果。其中三氯化铁、硫酸铁铵、氧化亚锡、PVC SO3H、聚氯乙烯 三氯化铁、D61和D72离子交换树脂、固体超强酸TiO2/SO42-、活性炭固载的磷钨酸和固载杂多酸盐TiSiW12O40/TiO2等9种催化剂的收率均在90%以上,且大多数不溶于反应体系中,易于分离,能重复使用,具有实际应用价值。
The experimental results of FeCl_3·6H_2O, Fe_2 (SO_4)_3 ·xH_2O, NH_4Fe(SO_4)_2, CuSO_4, SnO, niobic acid, PVC-SO_3H,polyvinyl chloride-ferric chloride(PVC-FeCl_3),macroporous ion exchange resin, Vitamin C, solid superacid SO_4^(2-)/ TiO_2, phosphotungstic acid supported on active carbon, tungstosilicic acid,supported TiSiW_(12)O_(40)/ TiO_2, HY-type molecular sieve, HZSM-5 molecular sieve and Fe-ZSM-5 molecular sieve,etc. 18 kinds catalysts for catalytic synthesis of cyclohexanone 1,2-propylene ketal by the ketalization of cyclohexanone with 1,2-propylene glycol are reviewed. It showed that the yields of FeCl_3·6H_2O, NH_4Fe(SO_4)_2, SnO, PVC-SO_3H, polyvinyl chloride-ferric chloride(PVC-FeCl_3),macroporous ion exchange resin, solid superacid SO_4^(2-)/ TiO_2,phosphotungstic acid supported on active carbon and supported TiSiW_(12)O_(40)/TiO_2 over 90%, most of these catalysts were not dissolved in reaction system, can be recovered from solutions simply and reused efficiently and has worth of practical application.
