To Isolate and Identify the Oxidation Production of Menadione by Physicochemical Methods

The result of oxidation of Menadione by Cerric Sulphate ion are summarized below:

(1) The specific rate is related to concentration of CuSO₄ by relationship. K = K0 + Conc. Cu²⁺

(2) The reaction is first order, both in Ce (IV) and Menadione.

(3) The mole ratio of reaction is two moles of Menadione to one mole Ce(SO₄)₂

(4) Final reaction product has been identified as rearrangement products of epoxide of Menadione.
