FIELD: chemistry.
SUBSTANCE: invention relates to chemistry of organochlorine compounds, and specifically to an improved method of producing chlorine-substituted aryloxycarboxylic acids through chlorination of acids of general formula 
where R1 is H, haloid, C1-C4alkyl, n is an integer ranging from 1 to 3, or salts thereof with subsequent extraction of the end product, wherein the chlorinating agent used is solid calcium hyprochlorite in the absence of solvents, and the process is activated by mechanical action in form of impact or impact-shear loading the mixture of solid reagents.
EFFECT: method increases output and purity of the end product, and also simplifies the process technology.
