One-pot liquid phase oxidation of cyclohexane to adipic acid with molecular oxygen catalyzed by meso-tetra (o-chlorophenyl) iron porphyrin(T(o-Cl)PPFe) under different conditions such as reaction temperature,reaction time,oxygen pressure and catalyst amount were studied.All parameters revealed significantly influence the yield of adipic acid and have optimal values respectively.T(o-Cl)PPFe was proved to be an excellent catalyst towards one-pot oxidation from cyclohexane to adipic acid favoring high turn ove...
