Abstract

Bis-N-chloramides of saturated aliphatic dicarboxylic acids are prepared by chlorinating a saturated aliphatic dicarboxylic diamide, the aliphatic residue of which has 4 to 40 carbon atoms, in an aqueous inorganic acid medium, at a temperature between 0.degree. and 40.degree. C.; the chlorination is advantageously carried out in presence of an inorganic salt.
