Abstract

L'INVENTION CONCERNE LA TRANSFORMATION D'UN OXYDE METALLIQUE EN UN CHLORURE METALLIQUE PAR REACTION AVEC DU CHLORE ET DU MONOXYDE DE CARBONE. ON MET EN CONTACT L'ACIDE CHLORHYDRIQUE SOUS-PRODUIT AVEC DE L'OXYGENE ET UN MELANGE DE SEL FONDU CONTENANT LES CHLORURES A VALENCE SUPERIEURE ET INFERIEURE D'UN METAL MULTI-VALENT, ON MET EN CONTACT LE SEL FONDU AVEC AU MOINS UNE FRACTION DE MONOXYDE DE CARBONE POUR RECUPERER PRATIQUEMENT TOUTE LA QUANTITE DE CHLORE AJOUTEE AU MELANGE DE SEL FONDU EN SEPARANT LE CHLORURE GAZEUX DU SEL ET EN EFFECTUANT UNE REACTION POUR PRODUIRE DU PHOSGENE, ON RECUPERE LE MONOXYDE DE CARBONE, LE CHLORE ET LE PHOSGENE ET ON LES UTILISE DANS LA PRODUCTION DE CHLORURE METALLIQUE. L'ACIDE CHLORHYDRIQUE RECUPERE PEUT ETRE UTILISE DANS LA PRODUCTION DE CHLORURE METALLIQUE.
