| Abstract: | The acetalization of cyclohexanone and 1,2 propanediol catalyzed by I 2 was studied. The effects of reaction time, reactant ratio, catalyst amount and the amount of water carrying agent on the yield of cyclohexanone 1,2 propanediol acetal was investigated. The results showed that the most suitable condition for the reaction are as follows: 1,2 propanediol/cyclohexanone molar ratio is 1.3, molar ratio of catalyst to reactant is 0.007%, cyclohexane as the water carrying agent is 8mL, reaction time is 40min. Under the conditions the yield is up to 79.2%. |
