| Abstract: | Cyclohexanone glycol ketal was directly synthesized from cyclohexanone and glycol under microwave irradiation using ammonium ferric sulfate as the catalyst. The effects of reactant mole ratio, catalyst dosage,microwave irradiation power and microwave irradiation time on the yield of cyclohexanone glycol ketal were investigated. The results showed that the optimal condition was as follows: n (cyclohexanone)∶n(glyco1)=1∶1.4, catalyst dosage=3.5% of the mass of the reactants, microwave irradiation power=450 W, radiation time=7 min. Cyclohexanone glycol ketal yield of up to 88.1% was obtained. |
