Abstract: A series of urushiol-metal polymers were synthesized and their properties were characterized by IR method,in which urushiol-Fe-C polymer was used as catalyst to synthesize isoamyl acetate. Factors affecting esterification yield such as material ratio,time of reaction and catalyst have been studied. The optimum conditions are as follows: material ratio of isoamyl alcohol to glacial acetic 0.6:1; dosage of catalyst 2.3%-3.4% of isoamyl alcohol; reaction time 3 h; yield of isoamyl acetate(IA) 88%.The purity of product is 99.5%. This catalyst has the advantage of less corrosion and can be reused.

Key words: urushiol-metal polymer, isoamyl acetate, catalytic synthesis
