| Abstract: | The synthesis of butanone glycol ketal with silicotungstic acid/silica as catalyst has been studied.Molar ratio of butanone to 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 to glycol is 1:1.5,the dosage of catalyst is equal to 0.6% of feed stocks,the volume of cyclohexane as the water-carrying agent is 10 mL and the reaction time is 75 ... |
