Abstract: Metal ions were grafted into the pores of SBA-15 and the grafted product was examined for using as catalyst in synthesis of cyclohexanone ethylene ketal.Structure of the catalyst was characterized by FT-IR,SEM and XRD.And the characterizing results show that the catalyst prepared is the targeted one.Then,experiment for the synthesis of cyclohexanone ethylene ketal was carried out with various catalysts.Experimental results show that as dosage of cyclohexanone is fixed at 0.2 mol;molar ratio of glycol to cyclohexanone is 1.7∶1;dosage of the catalyst is 1.2% (mass) of the reactants;volume of water stripping agent,cyclohexane is 14 mL;reaction time is 100 min;catalyst Co/SBA-15 displays the best result that the yield of cyclohexanone ethylene ketal achieves 89.8%.
