Title: Catalytic Synthesis of Cyclohexanon 1,2-Propanediol Ketal
Abstract: The catalyst prepared with sol-gel and in impregnation method was used to synthesize cyclohexanone 1,2-propanediol ketal with silica supported potassium aluminium sulfate(KAl(SO4)2/SiO2) solid acid so that factors of the product yield could be investigated in detail.The results show that the KAl(SO4)2/SiO2 has high catalytic activities.The optimal reaction conditions include the reaction time(70 min),molar ratio of cyclohexanone to 1,2-propanediol(1∶1.1) and catalyst mass fraction in the total reactants(5.0%).Under the above conditions the yield of cyclohexanone 1,2-propanediol ketal is 99.9%.
