Trichloroacetic acid - completely halogenated (methyl group), an analogue of acetic acid.
Trichloroacetic acid is a white hygroscopic crystals which are readily soluble in water and in organic solvents - alcohol, ether, acetone, benzene, carbon tetrachloride, methylene chloride, carbon disulfide.
Trichloroacetic acid is easily decarboxylated by boiling 1,2-dimethoxyethane, giving dichlorocarbene. Neutralization trichloroacetic acid aqueous NaOH or Na2CO3 leads to sodium trichloroacetate.
Trichloroacetic acid is highly toxic, absorbed through the skin, has a cauterizing effect. Has a pleasant smell, which can be misleading.
- Basic amount of TCA are to receive sodium trichloroacetate, widely used as a herbicide.
- It is used in biochemistry and medicine as an astringent and antiseptic. in cosmetics as an agent for a chemical peel.
- Is used in chemical synthesis, chromatography, as the differentiating solvent.
