Thioacetic acid is an organic compound. It has the same structure as that of acetic acid, however, the oxygen atom of the hydroxy group is replaced by sulfur.

Properties

Thioacetic has a lower boiling point than acetic acid. Thioacetic is a colorless to yellow, fuming at the air liquid with a pungent, unpleasant, fruity odor in sufficient dilution. Your vapors irritate and harm the eyes, the respiratory tract and the lungs and the skin.

Synthesis

Of glacial acetic acid by heating with phosphorus (V ) sulphide formed thioacetic acid. Alternatively Thioacetic are made from acetic anhydride and hydrogen sulfide. A synthesis of acetyl chloride and hydrogen sulfide is also described.

Use

It is used in organic chemistry for the introduction of thiol groups in molecules. In addition, it also serves for the destruction of peroxides as an alternative to aqueous reducing agents.
