ABSTRACT:
A process for producing monochloroacetic acid from hydroxyacetic acid which comprises feeding hydroxyacetic acid and aqueous hydrogen chloride to a reaction zone and contacting the hydroxyacetic acid with the aqueous hydrogen chloride in the presence of hydrogen iodide catalyst at a temperature between 100.degree. and 250.degree. C. and a pressure sufficient to maintain the aqueous hydrogen chloride in liquid phase. Preferably the reaction is carried out at a temperature between about 130.degree. and 200.degree. C.
