Progress on research of catalysts for synthesis of cyclohexanone 1,2-propylene ketal

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.
