Proceed with caution , however. The information provided in this article is intended for emergency situations only. Caution should be exercised when using any of the following information. Potassium permanganate will start a fire when mixed with a couple of different compounds. Glycerin is the most common, but antifreeze will also do the trick. Antifreeze seems to create a reaction that is a little more violent.
Be very careful when using either. The reaction is not always immediate. It can take several seconds for the reaction to start a fire — let it be.
After gathering all the necessary fire tinder and large pieces of wood to keep your fire going, place a teaspoon of Potassium permanganate on a flat surface. Carefully add the same amount of Glycerine or Antifreeze evenly on top of your pile.
Next, stand back a couple of feet and wait at the ready with your tinder. For water purification, its use is relatively straightforward. First, if there is any sediment in the water, strain it out. Then add 3 — 4 crystals per liter of water. Stir or shake for a few seconds then let sit for 2 hours. The water should be a light pink a concentration of , — no darker. But the basic idea is that the extra oxygen in the permanganate oxydizes the glycerine. Nitroglycerine is a completely different reaction and doesn't involve oxydation.
I read a few weeks back that the UK was considering censoring 'materials' that may prove useful to a 'terrorist'. So I prepared a webpage on how to make a quite high yield explosion using the above reaction.
If we outlaw basic science, only outlaws will have basic science and that scares the hell outta me. Manganate VII is a pretty strong oxidiser, the oxidation state should tell you that. Not sure if glycerine is ideal as a reduction agent, but it should work. Glycerin has 3 alcohols that can be oxidized to carbonyls, I imagine that would be quite a show.
I have done this before for demonstration purposes. The way to do this [without danger] is to get some sulfuric acid. Put the sulfuric acid in a test tube or beaker or something. Then slowly pour the glycerin on top of it - it will float. Now drop little pieces of the permanganate it. Watch them drop slowly through the glycerin until they hit the acid - they will "pop" into tiny fireballs. Be very careful if you try this - goggles and ventilation.
I am not advocating anybody doing this at all. In nitroglycerin, this is glycerin, in TNT, toluene. The process of detonation is different than combustion, but oxidation is key to both of them. Gycerol is the simplest triol -- molecule with three -OH alcohol groups. KMN04 is indeed a fairly strong oxidizer. No surprise that it reacts with just about anything with hydrocarbons which has a loose bond or two that it "can grab. Propenyl is the characteristic odor of "smoke" Propenyl is definitely not good for you, particularly in high concentrations.
Just burning glycerol in air does too -- glycerol burns like crap unless you have a sophisticated burner that heats the combustion air good and hot. Glycerol is hydrophilic, and it mixes well with alcohol and it doesn't mix with alkanes etc. Sometimes a dash of glycerol is added to alcohols to improve hypergolic ignition But that's about the only use I know for this hypergolic reaction In chemistry, an exothermic reaction is one that releases heat.
In an exothermic reaction, the total energy absorbed in bond breaking is less than the total energy released in bond making. In other words, the energy needed for the reaction to occur is less than the total energy produced. As a result of this, the extra energy is released, usually in the form of heat.
Oxidation of Alcohol. The outcome of oxidation reactions of alcohols depends on the substituents on the carbinol carbon. In order for each oxidation step to occur, there must be H on the carbinol carbon. Primary alcohols can be oxidized to aldehydes or further to carboxylic acids.
In aqueous media, the carboxylic acid is usually the major product. Secondary alcohols can be oxidized to ketones but no further. Tertiary alcohols cannot be oxidized. Students know how to identify reactions that involve oxidation and reduction and how to balance oxidation-reduction reactions. Students know chemical processes can either release exothermic or absorb endothermic thermal energy.
Students know how reaction rates depend on such factors as concentration, temperature, and pressure. Students know how to identify the functional groups that form the basis of alcohols, ketones, ethers, amines, esters, aldehydes, and organic acids. Chemical Volcano. Overview : This is a rapid oxidation of glycerin by potassium permanganate. Experiment Summary As the glycerin comes in contact with the potassium permanganate, the oxidizing properties of the permanganate ion come into play with the glycerin.
