| Abstract: | SO_4~(2-)-TiO_2/Al_2O_3 solid superacids as catalyst was prepared by the means of depositing and dipping.With SO_4~(2-)-TiO_2/Al_2O_3 solid superacids as catalyst,cylohexanone 1,2-propanediol ketal was synthesized from cyclohexanone and 1,2-propylene glycol by condensation reaction.What's more,it reviewed activated temperatures,load aounts of TiO_2,mixing ration of reaction materials,amounts of catalyst,reaction times,and the effect of water-carrying agency on condensation reaction. |
