| Abstract: | Butanone 1,2-propanediol ketal was prepared from butanone and 1,2-propanediol using silictungstic acid/SiO2 as a catalyst.Molar ratio of butanone to1,2-propanediol,the dosage of catalyst,the volume of cyclohexane as the water-carrying agent and reaction time on the yield were examined in the experiments.The optimum conditions are as follows: butanone is 0.2mol,molar ratio of butanone to 1,2-propanediol glycol is 1.0:1.5,the dosage of catalyst is equal to 0.8% of feed stocks,the volume of cyclohexane as the ... |
