The catalyst was prepared by cobalt(II) metal ions onto polymer support which was glycidyl metharylate- acrylonitrile- styrene-divinylbenzene copolymer with containing iminodiacetic acid chelate group. The catalyst was characterized by means of FTIR,BET,AA and SEM studies. The reaction products were characterized by FTIR, GC-mass, H1NMR. Among the testes catalysts, s30 gave the highest cyclohexane conversion 10.3% at the reaction time of 3h. The addition of co-catalyst to the oxidation of cyclohexane promotes the conversion and the selectivities. The addition of Benzaldehyde led to the increase of the conversion of cyclohexane from 10.3% to 14.4%, but the selectivity of cyclohexanol and cyclohexanone did not appreciably increase. The optimum reaction temperature was 403K. At 5MPa the obtained cyclohexane conversion and selectivity were 13.5% and 98.1%, respectively.
