production

Although methanol was first obtained by wood distillation, today it is produced entirely from the reaction of carbon monoxide with hydrogen in the presence of a catalyst. Generally, alloys of copper and zinc oxides are used as catalysts. Millions of tons of methyl alcohol are produced in the world every year.

General features

Metalol or methyl alcohol; It is a light, volatile, colorless, flammable liquid. It is extremely toxic to humans. It is the active ingredient in fake drinks. It is the simplest alcohol. Its taste is similar to ethyl alcohol. It burns with a pale blue flame that is invisible in daylight. It is also called wood alcohol because it is obtained by heating wood in an airless environment at first. Methyl alcohol is both a very good solvent and a raw material for many industrial chemicals. In addition, methanol is abundant in space in the regions of star formation. For astronomers, its abundance in a region is a sign that star formation will begin in that region.

Usage areas

Methanol is the main raw material used in the production of formaldehyde. In this way, it has a large area of ​​​​use. It is also the precursor to different industrial chemicals such as acetic acid and some hydrocarbons. Methanol is used as a general solvent in many different areas from wastewater treatment plants to polymer production. Although it was used in processes such as the production of antifreezes and fuels for spirit stoves, and the denaturalization of ethyl alcohol, its use in such areas is now prohibited in many countries due to the threat of drinking.

In addition to these, methyl alcohol is also used as a fuel or recording additive in internal combustion engines. Especially its use as a performance enhancing additive is very common all over the world. It is a suitable fuel source for engines due to its low flash point. At the same time, when it is used as a fuel additive, it facilitates the cooling of the engine and the air-fuel mixture, as it draws a lot of heat from its surroundings while passing from the liquid state to the gas state.

Safety Precautions and Toxicity

Methyl alcohol is very toxic to humans. Even ingestion of 10 ml of pure methanol can cause permanent blindness by destroying the optic nerves. 30 ml is potentially fatal. Methyl alcohol; It causes metabolic disorders by both affecting the nervous system and turning into toxic substances such as formaldehyde and formic acid in the liver. In these cases, the antidote should be taken as soon as possible.

Methyl alcohol, which is also highly flammable, is heavier than air. It can be ignited easily. Fires should be extinguished with dry chemical carbon dioxide and alcohol resistant foam fire extinguishers.
