Atsetanhüdriidi

Atsetanhüdriidi, also known as acetic anhydride, is a chemical compound with the formula (CH3CO)2O. It is the anhydride of acetic acid and is a colorless liquid with a pungent odor. Atsetanhüdriidi is widely used in organic synthesis as an acetylating agent. It reacts with alcohols and amines to form esters and amides, respectively. This reaction is often used to protect hydroxyl and amino groups during chemical reactions.

One of the primary industrial uses of atsetanhüdriidi is in the production of cellulose acetate, a plastic material used in photographic film, textiles, and cigarette filters. It is also used in the synthesis of pharmaceuticals, such as aspirin, and in the production of dyes and perfumes.

Atsetanhüdriidi is a corrosive substance and should be handled with care. It reacts vigorously with water to produce acetic acid, which is also corrosive. Due to its potential for misuse in the illicit production of heroin, the sale and distribution of atsetanhüdriidi are regulated in many countries.
