Question

Methyl alcohol is industrially prepared by the action of
A) $C{H_3}COC{H_3}$
B) $CO + {H_2}$
C) $C{H_3}COOH$
D) ${C_2}{H_5}OH$

Answer 1

Hint: Methanol $(C{H_3}OH)$, also known as methyl alcohol, wood alcohol, or wood spirit, is the most basic of a long sequence of organic compounds known as alcohols. It is made up of a methyl group $(C{H_3})$connected to a hydroxyl group $(OH)$. Previously, methanol was obtained through the destructive distillation of wood.

Complete answer:
Pure methanol is a crucial component of chemical synthesis. Its derivatives are used in large amounts to make a wide range of chemicals, including many essential synthetic dyestuffs, resins, pharmaceuticals, and perfumes. Dimethylaniline is used in dyes and formaldehyde is used in synthetic resins in large amounts.
Methanol is a colourless liquid that boils at $64.96$ degrees Fahrenheit and solidifies at \[93.9\] degrees Fahrenheit. It reacts with air to form explosive mixtures and burns with a nonluminous flame. In water, it is totally miscible. Methanol has a similar odour to ethyl alcohol, the intoxicant in alcoholic drinks, but it is a deadly poison; consuming mixtures containing it has resulted in many cases of blindness or death.
Modern methanol production relies on the direct reaction of carbon monoxide gas and hydrogen in the presence of a catalyst. Syngas, a mixture of hydrogen and carbon monoxide derived from biomass, is increasingly being used in the manufacture of methanol.
The activity of $CO + {H_2}$ is used in the industrial production of methanol or methyl alcohol as follows:
\[CO + {H_2}\xrightarrow{{230 - {{400}^\circ }C}}C{H_3}OH\]
Methanol/methyl alcohol is created when carbon monoxide reacts with hydrogen.
This reaction occurs at a temperature of $230^\circ C$ and a pressure of $50 - 100$ atm. Copper oxide on oxide chromium (III) can be used as a catalyst in this reaction.
The correct option is B.

Note:
It's also used in antifreeze for automobiles, rocket fuel, and as a general solvent. Methanol is also a high-octane, clean-burning fuel that could be a viable alternative to gasoline in automobiles. Methanol extracted from wood is primarily used to make synthetic ethyl alcohol unfit for use.
