The kinetics of the formation of Mn(III) hematoporphyrin in glacial acetic acid has been studied spectrophotometrically.On addition of Mn(II) to porphyrin in glacial acetic acid a species which appears to be the monocation immediately is formed and is then converted to Mn(III) hematoporphyrin at a rate suitable for kinetic studies.The rates of reaction were measured at 45, 50, and 55 °C and the activation energies were calculated.
