Description

Dichloroacetic acid, CHCI2COOH, also known as dichlorethanoic acid, is a corrosive, combustible, colorless, strong liquid acid with a pungent odor. It is soluble in water and alcohol. Dichloroacetic acid (Ka=5.14 × 10-2) is a stronger acid than chloroacetic acid. Most chemical reactions are similar to those of chloroacetic acid, although both chlorine atoms are susceptible to reaction. Dichloroacetic acid is much more stable to hydrolysis than chloroacetic acid. It is a reactive intermediate in organic synthesis. Dichloroacetic acid is prepared by the chlorination of acetic acid.
