Disclosed is a method for the simultaneous preparation of dicarbozylic acids and diamines from (a) polymers based on polyamides made by reacting dicarboxylic acids or derivatives thereof with diamines or (b) compounds containing essentially such polymers, by decomposing these polymers into their constituent monomers by treating the polymers or compounds with a base in an alcoholic solution and subsequently converting electrochemically the dicarbozylic-acid salts thus produced into the corresponding dicarboxylic acids and bases.
Procédé de préparation simultanée d'acides dicarboxyliques et de diamines à partir (a) de polymérisats à base de polyamides résultant de la réaction d'acides dicarboxyliques ou de leurs dérivés avec des diamines, ou (b) de matières renfermant essentiellement de tels polymérisats, par décomposition de ces polymérisats en leurs constituants monomères, consistant à traiter ces polymérisats ou ces matières avec une base, en milieu alcoolique, puis à transformer par voie électrochimique les sels d'acides dicarboxyliques ainsi produits en acides dicarboxyliques et bases correspondants.
