Some Commercially Important Alcohols

The video tutorial explains the production and uses of methanol and ethanol. Methanol, also known as wood spirit, was traditionally produced by the destructive distillation of wood but is now made through catalytic hydrogenation of carbon monoxide. It is a colorless, highly poisonous liquid used as a solvent and in making formaldehyde. Ethanol is produced by fermenting sugars from sources like grapes, using enzymes like zymase. It is a colorless liquid used in industries as a solvent and in organic compound preparation. Ethanol is denatured to prevent consumption by adding copper sulfate and pyridine.
