BeschreibungChloroacetic acid (CAA) is a monohalogenated acetic acid (m-HAA) that is used as a photosensitizing agent and in industrial synthesis of certain organic chemicals such as indigoid dyes. The m-HAAs are a major class of drinking water disinfection by-products during chlorination of drinking water.
VerwendenChloroacetic acid behaves as a very strong monobasic acid and is used as a strong acid catalyst for diverse reactions. The Cl function can be displaced in base-catalyzed reactions.

DefinitionA colorless crystalline solid made by substituting one of the hydrogen atoms of the methyl group of ethanoic acid with chlorine, using red phosphorus. It is a stronger acid than ethanoic acid because of the electron-withdrawing effect of the chlorine atom. Dichloroethanoic acid (dichloroacetic acid, CHCl2COOH) and trichloroethanoic acid (trichloroacetic acid,CCl3COOH) are made in the same way. The acid strength increases with the number of chlorine atoms present.
