उत्तर
Denatured alcohol is ethyl alcohol in which small amounts of poisonous substances like methanol and copper sulphate are added to make it unfit for consumption.
Ethyl alcohol is used for manufacturing various products in different industries. Therefore, government supplies ethyl alcohol to the industries without charging production tax. In order to prevent the misuse of ethyl alcohol for drinking purposes, it is denatured by adding poisonous substances such as methanol, pyridine or copper. This makes the alcohol unfit for consumption.
