Cobalt(II) tetraphenylporphyrins catalyzed the autoxidation of acetaldehyde giving peracetic acid quantitatively. The <I>p</I>-substituents of phenyl groups of tetraphenylporphyrin influenced the catalytic activity, cobalt(II) tetra(<I>p</I>-methylphenyl)porphyrin being remarkably active. The effect of the base added into the reaction system was such that an appropriate quantity of the base gave rise to a maximum rate of oxidation. The rate equation was determined experimentally. From the results of kinetics and ESR study, it was concluded that an oxygen molecule activated through the electron transfer from a cobalt(II) ion abstracted the hydrogen of acetaldehyde to initiate the autoxidation.
