Abstract: The influence of additive isopropyl alcohol, pyridine, hydrochloric acid and sodium hydrate in different quantities on the catalytic characteristics of chloro tetraphenyl-porphinato iron TPPFeCl and (TPPFe)₂O in above reaction was studied. It is found that isopropyl alcohol and pyridine in small amounts could increase the yield of oxidation product of cyclohexane. The presence of cyclohexanol could give a longer catalytic lifetime of TPPFeCl. The catalytic oxidation of cyclohexane could be favourable as a small amount of aqueous NaOH was added; but unfavourable as hydrochloride acid was added. This reaction was unfavourable either when the polarity of solvent increased. One of the oxidation products of cyclohexane, cyclohexanone, was verified to be mainly produced by oxidizing cyclohexanol directly by PhIO. The presence of TPPFeCl was unfavourable to form cyclohexanone.
