Methanol is widely used alcohol that is used in the industrial adhesives and antifreeze industries. Methanol is also known by other names such as methyl alcohol, methyl hydrate, methyl hydroxy, and wood alcohol.
Methanol is one of the three most important substances in the chemical industry which various chemicals can be derived from it. in standard conditions, this alcohol is a colorless, flammable liquid.
One of the most important uses of methanol is in the production of acetic acid formaldehyde and polyesters. The chemical formula of this alcohol is CH3OH.
Wood alcohol is commonly used as a solvent in the chemical industry and the production of inks, adhesives, and resins, and in the manufacture of fuels or antifreeze.
Methyl hydroxy can be found in many of the foods we eat daily. This alcohol is found in a variety of vegetables and fruits. Prolonged exposure to this chemical can be harmful to human health, it is better to pay attention to all safety and health points.
In the following, we will learn more about the physical and chemical properties and important applications of this flammable chemical.
Physical and chemical properties of methanol:
Methanol is generally considered a toxic substance, it is chemically light and volatile, this flammable chemical has a methyl group in its structure and its acidity is higher than water, methyl hydroxy is a polar solvent that is produced for industrial use, mainly by carbon monoxide hydrogenation.
The chemical structure of methanol is as follows:
The most important physical and chemical properties of wood alcohol can be summarized in the following table:
|Molecular weight (g/mol)||32.04|
|Boiling point (°C)||64.7|
|Melting point (°C)||-97.6|
This alcohol is in the industrial chemicals category of shanghai Chemex company.
The first methanol production method used in the past was the carbon monoxide catalytic hydrogenation method.
During this process, a mixture of hydrogen and carbon monoxide reacts with a certain stoichiometric ratio, and the reaction of water with methane at high temperatures was aided.
Over time, new production methods were used for methanol, one of which has recently received much attention is the use of catalysts that increase the efficiency of the reaction while still reacting at low temperatures.
In the past, the gas required for the wood alcohol production process was obtained from coal, but today this gas is obtained from the reaction of methane in natural gases at a certain pressure and temperature.
Carbon monoxide and hydrogen produced in the presence of an aluminum catalyst react to produce methanol.
Application and uses of Methanol:
- Methanol is widely used in the production of plastics; this solvent is used in the production processes of polyethylene (PE) and polypropylene (PP)
- Large volumes of gasoline fuels are produced with the help of this colorless liquid, the combination of methanol and gasoline has a positive effect on fuel efficiency.
- The use of wood alcohol in the production of fuels used by cars has increased.
- Production of various paints and coatings is done with the help of methanol, in general, this solvent has many applications in the paint and resin industry.
- Methanol is widely used in the textile and leather industries.
- The corrosion inhibitor industry also uses this material.
- Methyl hydrate is also used to make antifreeze.
- Another widespread use of methanol is in the production of personal care products.
Safety; what methanol does to your body?
Prolonged exposure to high concentrations of methanol can cause various poisonings.
Absorption of this chemical can be done by the skin or by inhalation, if a person has been poisoned by methyl hydrate, the best and most effective way is to expose them to the open air.
If part of her skin has been in contact with methanol, it is best to wash that part thoroughly with water.
If swallowing this solvent, it is better to give a few glasses of water to the poisoned person.
Methyl hydroxy is released into the environment during industrial processes or naturally from volcanic gases, vegetation, and microbes.
Exposure may occur through ambient air or when using solvents. Acute (short-term) or chronic (long-term) poisoning from human exposure to methanol by inhalation or consumption may result in blurred vision, blindness, headache, dizziness, and nausea.
Carefully follow all safety tips when working with this material, use masks, goggles, and special clothing.
Transporting and uses:
Use a cool and dry place to store this chemical. Try to store away from heat and direct sunlight. Shanghai Chemex is one of the most reputable manufacturers of this chemical in the world.
