Methanol Formula

The chemical formula for methanol is CH3​OH. It is the simplest of alcohols since it contains only one carbon atom, three hydrogen atoms, and one hydroxyl group (-OH). 

Physical properties

State: Methanol, under ambient conditions of temperature and pressure, is in a liquid state.

Color: It is a colorless liquid.

Odor: Methanol has a very slight, alcohol-like odor.

Boiling Point: A boiling point of about 64.7°C or 148.5°F.

Melting Point: Methanol has a melting point of about -97.6°C or -143.7°F.

Density: The density of methanol, at 20°C, is approximately 0.7918 g/cm³.

Solubility: Methanol is highly soluble in water; it is completely miscible in all proportions. It is soluble in most organic solvents, such as acetone and ether.

Viscosity: Methanol has a pretty low viscosity compared to most liquids.

Refractive Index: The refractive index for methanol is approximately 1.328.

Flammability: Methanol is flammable, and its vapors mix explosively with air. The flash point of methanol is about 11°C (52°F).

Chemical properties

Combustion: Methanol combusts in oxygen to yield carbon dioxide and water. The combustion reaction is exothermic and may be represented by

Methanol Formula

Oxidation: Under controlled conditions, methanol can be oxidized to formaldehyde or further to formic acid. The oxidation may be represented by

Methanol Formula

Esterification: Alcohol reacts with carboxylic acids to form esters and water in a process called esterification. For instance, the reaction of methanol with acetic acid produces methyl acetate

Methanol Formula

Reaction with Sodium: Methanol has the property of reacting with the metal sodium to form sodium methoxide and hydrogen gas.

Methanol Formula

Dehydration: In acidic conditions, methanol can undergo dehydration to form dimethyl ether.

Methanol Formula

Formation of Methanol Halides: Methanol reacts with the halogenating agents, hydrochloric acid or bromine to form methanol halide, that is methyl chloride or methyl bromide, respectively.

Methanol Formula

Application

Solvent: It has wide application as a solvent in pharmaceuticals and is used in the production of plastics and dyes; it also finds use in carrying out various chemical reactions and analyses in laboratories.

Fuel: It serves as a fuel and a fuel additive. Applications also include the production of biodiesel and a few renewable energy technologies.

Antifreeze: Methanol has a low freezing point and, hence, is used as an antifreeze in automotive cooling systems and also for de-icing aircraft.

Chemical Feedstock: Methanol is an important raw material for the manufacture of a variety of chemicals. Some of these include:

Formaldehyde, acetic acid, methyl methacrylate, methanol-based chemicals, and pharmaceuticals, and also used in preservation and extraction techniques. 

Cleaning Agent: It finds use in cleaning electronic parts, as well as precision instruments, because of its ability to dissolve a wide variety of materials.

Cosmetics and Personal Care: Methanol is utilized in several personal care items and cosmetics, normally as a carrier or solvent for the rest of the ingredients in the formulation.

Research and Development: In research laboratories, methanol is utilized in frequent experiments and develops a huge amount either as a solvent or in various chemical reactions.

Detoxification: Methanol is sometimes used in detoxification processes during the treatment of methanol poisoning by using ethanol as an antidote, which inhibits methanol metabolism.

Conclusion

Apart from being one of the interesting chemicals, methanol has its applications running from solvents and fuels to antifreeze and feedstock chemicals. It means that it has great variability in industry, medicaments, and research work; however, it is toxic and needs caution and safety in handling. As a large-volume chemical feedstock and source of energy, methanol remains of critical importance in many industries today, even while its use is controlled to minimize its health and environmental hazards.
