Catalytic Synthesis of Butanone 1,2-Propanedioi Ketal with H4 SiW12 O40/ZrO2-Al2O3
Abstract:H4SiW12 O40/ZrO2-Al2O3 was prepared by impregnation, and characterized by FT-IR and XRD. Catalytic activity of H4SiW12 O40/ZrO2-Al2O3 was evaluated by the synthesis of cyclohexanone 1,2- propanediol ketal. The factors influencing the synthesis were discussed. The optimum conditions are. mo- lar ratio of butanone to 1,2-propanediol glycol is 1 : 1.5, the quantity of catalyst is equal to 1.5 % of feed stocks, the volume of cyclohexane as the water-carrying agent is 8mL, and the reaction time is 60 min. H4SiW12 O40/ZrO2-Al2O3 is an excellent catalyst for synthesizing butanone 1, 2-propanediol ketal and its yield can be up to 78.1%.
