Abstract

"Process for obtaining dimercapto-benzoic acids" of general formula ** (See formula) ** without the three substituents, as well as their alkaline and alkaline earth salts, being characterized, characterized in that a halogen 2,4-dihalo-sulfonyl benzoyl is reduced where the halogen supposes a chlorine or bromine atom, the reduction product is benzylated , the composition is treated with butyl lithium and carbon dioxide, the reaction mixture is acidified and the benzylic groups are dissociated, the dimercaptobenzoic acid obtained is transformed, if desired, into its alkaline or alkaline earth salts.
