About 40% of the worldwide production of Methanol for the production of formaldehyde. Deshpande D.D. Ethyl alcohol is the form found in most alcoholic beverages. Large quantities are converted to dimethylaniline for dyestuffs and to formaldehyde for synthetic resins. Methyl alcohol, or wood alcohol, is used for a variety of household purposes.…. Aust.J.Chem. Methanol (CH3OH), also called methyl alcohol, wood alcohol, or wood spirit, the simplest of a long series of organic compounds called alcohols, consisting of a methyl group (CH3) linked with a hydroxy group (OH).

Methanol is a colourless liquid that boils at 64.96 °C (148.93 °F) and solidifies at −93.9 °C (−137 °F). Its derivatives are used in great quantities for building up a vast number of compounds, among them many important synthetic dyestuffs, resins, pharmaceuticals, and perfumes. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. It forms explosive mixtures with air and burns with a nonluminous flame. Methanol, also known as methyl alcohol amongst other names, is a chemical with the formula C H 3 O H (a methyl group linked to a hydroxyl group, often abbreviated MeOH). 10 0 obj << /Length 11 0 R /Filter /FlateDecode >> stream This article was most recently revised and updated by, https://www.britannica.com/science/methanol, Royal Albert Hall - The enduring legacy of Proms co-founder Sir Henry Wood, methanol - Student Encyclopedia (Ages 11 and up). plastics, plywood, paints, explosives, Zh.Fiz.Khim. The modern method of preparing methanol is based on the direct combination of carbon monoxide gas and hydrogen in the presence of a catalyst. It is also used in automotive antifreezes, in rocket fuels, and as a general solvent. It is a critical component of hundreds of chemicals like olefins and formaldehyde. ; Gordienko O.I. : Heat Capacities at Constant Volume, Free Volumes, and Rotational Freedom in Some Liquids.

Maximum power outputs of 18.5 and 27 mW/cm 2 were obtained in the case of the CP, compared to 16 and 24.7 mW/cm 2 in the case of CC at 1 and 2 M, respectively. Increasingly, syngas, a mixture of hydrogen and carbon monoxide derived from biomass, is used for methanol production. Methanol has an odour that is similar to ethyl alcohol, the intoxicant of alcoholic beverages, but is a dangerous poison; many cases of blindness or death have been caused by drinking mixtures containing it. The methanol derived from wood is used chiefly for rendering industrial ethyl alcohol unfit to drink.
