Abstract: The kinetics of oxygen-uptake in DMF medium for MPc and MTPP catalytic systems has been investigated by means of measuring the absorbance variation vs time. According to a consecutive reactive mechanism, the activities of MP catalytic systems are in the order.
MPc>MTPP; Fe>Co>Cu
The reaction rates of MTPP with oxygen in air are less than that with pure oxygen, the ratio is roughly the same as to the partial pressure of oxygen in air. The influences of S-ligand ethanethiol and O-ligand Vc on the above systems have also been investigated, the former makes the MP bands having more changes and the reaction rate constants becoming greater, the latter has less influence.
