Abstract:  

The catalytic activity of potassium dodecatungstocobaltate trihydrate (K5CoW12O40·3H2O) on the reaction between cyclohexanone and 1,2-propylene ketal. The effects of the cyclohexanone/1,2-propylene alcohol molar ratio, the amount of the catalyst agent and water-carrying agent, the reaction time, the using regenerated catalyst on the yield of Cyclohexanone1,2-propylene ketal were systematically investigated. The results show that potassium dodecatungstocobaltate trihydrate (K5CoW12O40·3H2O) is a good water-carrying agent for the reaction between cyclohexanone and 1,2-propylene ketal. The results showed that the suitable condition for the reaction are as follows: benzaldehyde/1,2-propylene molar ratio is 1∶1.4, the amount of potassium dodecatungstocobaltate trihydrate (K5CoW12O40·3H2O) is 0.5 g, the volume of cyclohexane is 9 mL, and reaction time is 70 min. The maximum yield of benzaldehyde 1,2-propylene ketal is up to 94.2%.
