Compared with liquid alcohol, solid alcohol is safer. As a solid fuel, it is widely used in catering, tourism and field work. Solid alcohol, or solidified alcohol, is convenient to use, transport and carry, and causes little environmental pollution when burning. In recent years, various methods of curing industrial alcohol have appeared.

1, solid alcohol can be divided into colloid and solid, which has the characteristics of small volume, high heat, easy carrying (suitable for long-distance transportation) and safe use. When in use, it can be ignited by a match, and it is smokeless when burning, and the flame temperature is uniform, and the temperature can reach about 600℃. Combustible for more than 1.5 hours per 250 g.

2. Inferior alcohol blocks are unsafe. The raw material of solid alcohol should be industrial alcohol, but some small workshops use methanol as raw material in order to save costs. When solid alcohol burns, it will produce gases such as carbon dioxide and sulfur dioxide, and it will also volatilize formaldehyde and methanol, which will eventually be mixed into harmful gases with different components. This is also the reason why sometimes eating hot pot will smell obvious pungent smell.

3. Methanol vapor can enter the body through the respiratory tract, causing poisoning. It has been reported that in the processing point where methanol is used as raw material to make solid alcohol, workers are blinded by inhaling methanol vapor.
