The first syllable is pronounced with a short "i" sound, followed by the stress on the second syllable.

Denatured alcohol refers to ethyl alcohol that has been rendered unfit for human consumption by the addition of certain chemicals or compounds. This alcohol, often known as methylated spirits, has been modified to discourage its use as an alcoholic beverage. Denatured alcohol is primarily used for industrial purposes, such as cleaning, as a fuel in camping stoves, and in the production of many household products.
The process of denaturing involves introducing substances, such as methanol, acetone, or denatonium, into the alcohol, resulting in a bitter taste or unpleasant smell. These additives make the alcohol toxic or unpalatable, thus ensuring its safe handling and discouraging its misuse for drinking purposes. Denatured alcohol typically contains a high percentage of ethanol, usually around 90% or more.
Due to its properties, denatured alcohol possesses several practical applications. It is commonly used as a solvent and cleaning agent in various industries, including pharmaceuticals, paints, and cosmetics. It can effectively dissolve many substances and is utilized in the production of various products, such as perfumes, antiseptics, and detergents. Denatured alcohol is also employed as a fuel for heating, lighting, and camping stoves, and it serves as a safe alternative to flammable substances.
In summary, denatured alcohol refers to ethyl alcohol that has been altered by the addition of chemicals to make it unsuitable for human consumption. It has diverse industrial applications as a solvent, fuel, and cleaning agent, contributing to the production of numerous household and commercial products.
