Abstract
PROCEDE DE PRODUCTION DE SOLUTIONS DE CHLORURE DE ZINC SANS FER, NI ALUMINIUM. UNE SOLUTION ACIDE DE CHLORURE DE ZINC, CONCENTREE ET CONTENANT DU FER ET DE L'ALUMINIUM EST AJUSTEE A UN PH COMPRIS ENTRE 1,5 ET 3, ET EST PORTEE A UNE TEMPERATURE DE 150 A 260C EN AUTOCLAVE SOUS UNE PRESSION DE 6 A 48BARS. ON A AJOUTE EVENTUELLEMENT UN AGENT D'OXYDATION, OU ON A AUGMENTE LA PRESSION PARTIELLE D'OXYGENE DANS L'AUTOCLAVE POUR QUE LE FER SOIT SOUS FORME TRIVALENTE. LE FER ET L'ALUMINIUM PRECIPITENT SOUS FORME D'HYDROXYDES OU D'OXYDES HYDRATES, L'OPERATION DURANT DE 0,1 A 3HEURES. ON REFROIDIT ALORS BRUTALEMENT LE MILIEU REACTIONNEL, PAR DETENTE DE L'AUTOCLAVE, PUIS ON FILTRE ET ON LAVE LE PRECIPITE, QUI NE RETIENT QUE PEU D'EAU ET PRATIQUEMENT PAS DE ZINC. LA SOLUTION DE CHLORURE DE ZINC PURIFIEE EST RECUPEREE, OU, SI LES TENEURS DE DEPART EN FER ET ALUMINIUM ETAIENT TROP FORTES POUR QUE LA PRECIPITATION SOIT COMPLETE, ON REPREND L'OPERATION DE PRECIPITATION APRES AJUSTEMENT DU PH PAR AJOUT D'OXYDE DE ZINC.
