Dry fuel (dry alcohol)

Dry fuel (dry alcohol) 25kg, wholesale, also called dry alcohol, is available in white tablets, obtained by pressing a mixture consisting of hexamethylenetetramine (urotropine) and a small amount of paraffin. When burning tablets, a yellow-blue flame appears without soot. Fuel retains its shape, does not spread during combustion and does not leave ash.

The production of dry fuel is based on the production of urotropine by mixing formaldehyde with ammonia dissolved in water. This method was proposed back in 1859 by A.M. Butlerov. The advantage of this material for use as a fuel is the ease of use. It is easy to light it, to extinguish the flame it is enough to stop the access of oxygen by covering it with a crucible or other convex object.

The specific heat of combustion of dry alcohol is 31,300 MJ/kg. It is often included in the food rations issued to soldiers, usually complete with a special metal stand, the dimensions of which correspond to the fuel and ensure ease of use. This material serves as fuel in small models of steam engines and allows many types of chemical reactions to be carried out in the laboratories of educational institutions.

Before use, the tablets must be placed on a fireproof surface: a metal plate, ceramic tile, asbestos sheet. The most common use of dry alcohol is to warm up or cook food in the absence of other sources of fire in hiking trips, when deploying a tent camp by humanitarian or military organizations.

Due to the difficulty in regulating the power of the flame, dry fuel is easier to heat rather than cook food. To protect the flame from gusts of wind, it is enough to install any screen. The disadvantages of this material include its cracking with sparks flying to the sides when the tablets are damp. Due to its higher cost, this type of fuel is less common than gasoline or ethanol.

The chemical formula is (СH3CHO)4.

Where is it applied?

For heating or cooking in the field by tourists, military and rescue organizations;

As part of an army food ration, often a metal stand is included in the kit according to the size of a fuel tablet for ease of use;

As fuel for miniature models of steam engines, such as those made by Wilesco or Mamod.

As an inhibitor when removing corrosion products from steel parts with hydrochloric acid in accordance with GOST R 9.907-2007. In addition, it is used by some artisanal producers of alcoholic beverages as an amplifier of the alcohol intoxication they cause, which can cause severe poisoning, even death.
