Abstract: The catalytic activities of ten dialkyltin compounds containing silicon were investigated through the condensation reaction of acetal(ketal)-alcohol. Factors such as amount of catalyst, reaction time, molar ratio of aldehyde(ketone) to alcohol and solvent kind were studied toward the yield of reaction. The results show that, except one catalyst, nine compounds are good in catalytic activities for the acetalization and ketalization. The yield reached 92% and 86% under optimal compounds: catalyst dosage was 1.4% based on the mass of the reactants, the molar ratio of the aldehyde to goycol was 1∶1.3, ketone to goycol was 1∶1.9, cyclohexane was used as the water carrying agent, and the reaction was refluxed for 3 h.

Key words: dialkyltin containing silicon, catalytic activity, acetalization, ketalization
