Abstract
D'APRES CES AMELIORATIONS, ON REALISE AU DEPART UNE ETAPE DE REACTION OU LE CHLORURE DE POTASSIUM EST MIS EN CONTACT AVEC UNE SOLUTION D'ACIDE NITRIQUE DILUE PROVENANT D'UNE ETAPE DE RECUPERATION DE L'ACIDE PAR REEXTRACTION, ET AVEC UNE SOLUTION D'ACIDE NITRIQUE CONCENTRE, CE QUI PERMET DE DISSOUDRE TOUT LE CHLORURE DE POTASSIUM ALIMENTE ET D'EVITER TOUTE CRISTALLISATION DU NITRATE DE POTASSIUM FORME POUR REALISER ENFIN UNE ETAPE DE SEPARATION DES IMPURETES INSOLUBLES ACCOMPAGNANT LE CHLORURE DE POTASSIUM DU MELANGE DE REACTION OBTENU, LAISSANT CE DERNIER COMPLETEMENT CLARIFIE ET DEPOURVU DE SOLIDES. CES AMELIORATIONS PERMETTENT DE REALISER IMMEDIATEMENT APRES L'ETAPE DE REACTION UNE SEPARATION COMPLETE DES IMPURETES INSOLUBLES DU CHLORURE DE POTASSIUM, CE QUI PERMET D'ELIMINER TOTALEMENT LES PROBLEMES ENTRAINES PAR CELLE-CI ET D'ABOUTIR A UN NITRATE DE POTASSIUM BLANC D'UNE PURETE ELEVEE, APTE A TOUTE UTILISATION
