Reaction of Potassium Permanganate and Glycerine Addition of glycerin to a pile of potassium permanganate produces white smoke and a purple flame. The reaction is not instantaneous, but depends on the fineness of the solid crystals. Equation: 14 KMnO4 + 4 C3H5(OH)3 --> 7 K2CO3 + 7 Mn2O3 + 5 CO2 + 16 H2O Reference B. Z. Shakhashiri, "Chemical Demonstrations", Vol. 1, The University of Wisconsin Press, Madison ,Wisconsin, (1983) p. 83. See the Web Links page for a cool video of the reaction!
