PRODUCTION OF MALACHITE GREEN BY OXIDATION OF ITS LEUCO BASE USING POTASSIUM PERSULPHATE, POTASSIUM PERMANGANATE AND MANGANESE DIOXIDE
AbstractMalachite green dye was produced by oxidising the Malachite leuco base with some inorganic oxidants. Best product yield was obtained with manganese dioxide, while potassium permanganate gave better results than potassium persulphate. Dye yield was influenced by the optimum quantity of oxidant applied
