英文摘要：

The catalytic properties of organotin compounds containing silicon, bis （ （trimethylsilyl） methyl） tin dichloride and tri （ （trimethylsilyl） methyl） tin chloride, were observed in the synthesis of acetophenone cylic ethylic ketal. The factors which affected the reactions, such as catalyst dosage, reaction time, and solvent kind etc. , were discussed. The results showed that organotin compounds containing silicon exhibited good catalytic activities for synthesis of acetophenone cylic ethylic ketal. The yield reached 85.1% under optimal compounds ： mole ratio of aeetophenone to ethylene glycol 1 ： 1.9, catalyst dosage was 1.3% based on the mass of the reactants, cyclohexane as water carrying agent,the amount was 15 mL, and the reaction time was 3h.
