When ethanol is heated with alkaline potassium permanganate then it produces ethanoic acid due to complete oxidation. 3. Ethanol is the only primary alcohol which will give the reaction and ethanal the only aldehyde. 3. Aldehydes and formic acid (and formates) also give a positive test. As the glycerin comes in contact with the potassium permanganate, the oxidizing properties of the permanganate ion come into play with the glycerin.The oxidation of the glycerin is very exothermic and after a few seconds the released heat causes the glycerin to also ignite and burst into flame and release smoke. I don't see a connection of this reaction with ozone, besides of the fact, that permanganic acid is able to form ozone out of (aerial) oxygen: A watch glass bowl with a thin layer of concentrated sulfuric acid, a crystal of potassium permanganate thrown into - you will smell ozone.
