Acyl halides of chloro-substituted hydroxybenzoic acids (CSHBA) are used as intermediates for production of amides, anilides, and esters having high pesticidal activity. The reactions of alkali salts of 3-chloro-, 5-chloro-, and 3,5-dichloro-2-hydroxybenzoic acids with thionyl chloride for synthesis of any chlorides were studied. The influence of temperature and initial component ratio was studied. On the basis of experimental results, optimal conditions are suggested.
