The urushiol-iron-tin polymer was analysed by IR spectrum.Catalytic synthesis of esters and ketals with urushiol-iron-tin polymer as catalyst was studied.Beside,the reaction mechamism was discussed.The result shows that there is M-O(Fe-O?Sn-O)bond in the urushiol-iron-tin polymer,It is considered that the action center of catalyst is M n+ (Fe 3+ ?Sn 4+ ).In the presence of urushiol-iron-tin polymer catalyst,the esters and ketals can be synthesized,such as n-butyl acetate,n-butyl acrylate,thylene glycol monoethylether acetate and cyclohexanone-ethylene glycol ketal.The catalyst can be reused and regenerated.
