Title: Catalytic Synthesis of Butanone 1,2-Propanediol Ketal with H_4SiW_6Mo_6O_(40)/SiO_2
Abstract: The synthesis of butanone 1,2-propanediol ketal with H4SiW6Mo6O40/SiO2 as catalyst has been studied. Molar ratio of butanone to1,2-propanediol glycol, the dosage of catalyst, the volume of cyclohexane as the water-carrying agent and reaction time on the yield were discussed and the best conditions were found out. The optimum conditions are: molar ratio of butanone to1,2-propanediol glycol is 1:1. 4, the dosage of catalyst is equal to 1.4% of feed stocks, the volume of cyclohexane as the water-carrying agent is 10 mL,and the reaction time is 70 min. H4SiW6Mo6O40/SiO2 is an excellent catalyst for synthetizing butanone 1,2-propanediol ketal and its yield can reach over 83.1%.
