Abstract

Phenylalanine is oxidized by Mn(III) in sulfuric acid-water medium.
Effect of rate by potassium permangnate, MnSO₄, H₂SO₄, HCIO₄, ionic
strength, sodium pyrophosphate and temperature has been studied.
Energy of activation is 91.54 kjoule mole^-1. Oxidation is affected by
both Mn(III) and Mn(IV). Kinetically Mn(OH)²⁺ and HMnO₄^3- are the
active oxidising species. A free radical mechanism is suggested.
