äädikhüdriidi
äädikhüdriidi is a chemical compound with the formula C4H6O3. It is the anhydride of acetic acid, meaning it can be formed by the removal of a water molecule from two molecules of acetic acid. It is a colorless liquid with a pungent odor, similar to that of vinegar, though much stronger. äädikhüdriidi is highly reactive and is a powerful acetylating agent, meaning it readily transfers an acetyl group (CH3CO-) to other molecules. This reactivity makes it a useful reagent in organic synthesis for the production of various esters, ethers, and other compounds. It is often used in the pharmaceutical industry and in the production of dyes and explosives. äädikhüdriidi reacts exothermically with water, producing acetic acid. It also reacts with alcohols to form esters and with amines to form amides. Due to its corrosive and irritating nature, it must be handled with appropriate safety precautions, including good ventilation and protective gear.
