Solid state coordination reaction of Cu(OAc) 2·H 2O with phenoxyacetic acid has been investigated in the microwave oven. It is shown that anhydrous copper(Ⅱ) phenoxyacetate can be synthesized by solid state reaction,the reaction is four up to twenty eight times faster and the yield is higher under microwave irradiation than by conventional heating. The best reaction's condition has been found out by single variable counterchange means,the results showed that the yield is highest when microwave power is 800 W and irradiation time is 15 min and Cu(OAc) 2·H 2O to ArOCH 2COOH's mole ratio is 1∶2. The copper(Ⅱ) salt,ligand and complex's restraining bacteria's property have been examined,the results show that the least concentration of CuSO 4·5H 2O to restrain bacteria growth's is 110 mg/kg,phenoxyacetic acid is 280 mg/kg,copper(Ⅱ) Phenoxyacetate is 250 mg/kg.
