| Abstract: | Cyclohexanone ketal was synthesized from ketal by silicotungstic acid which was absorbed in acticarbon. The factors of the affects on the ketal reaction were examined, which gave the optimum conditions with 1∶1.5 molar ratio of ketone and alcohol, 1.5g adsorbing catalyst and 15ml carrier water, 21.9% the adsorbing quantity of the silicotungstic acid and reflux for 3h. The yield of the product was 91.6%, The catalyst has high stability. |
