Properties
Transport:UN 1839/2564
Flash Point: Not considered to be a fire hazard
Density:1.6298
Stability:Stable, but moisture sensitive. Incompatible with water, strong bases. Note that the Merck Index states that this material is hydrolytically unstable in aqueous solution below 30% by weight. Decomposition products include carbon monoxide and carbon dioxide. The generation of these gases in a sealed container may lead to a pressure rise sufficien
Refractive index:n20/D 1.62(lit.)
Solubility:soluble
Appearance:clear to white flakes
Specification:

1.Chemical Properties: Trichloroacetic acid (76-03-9) is white solid .
2.General Description: Trichloroacetic acid, solid is a colorless crystalline solid. Trichloroacetic acid absorbs moisture from air and forms a syrup. Trichloroacetic acid is soluble in water with release of heat. Trichloroacetic acid is corrosive to metals and tissue.
3.Air & Water Reactions: Trichloroacetic acid is soluble in water with release of heat.
4.Reactivity Profile: Trichloroacetic acid is a strong acid; when heated, in the presence of water, decomposes forming phosgene and HCl. [Handling Chemicals Safely 1980 p. 915]. The acid was added to copper wool and rinsed down with dimethyl sulfoxide. This caused what was thought to be an extremely exothermic dehydrohalogenation reaction that melted the neck of the flask, [Chem. Eng. News, 1981, 59(28), 4].
5.Health Hazard :Toxic; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
6.Fire Hazard: Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
