Abstract
PROCEDE DE PREPARATION DU SULFATE DE POTASSIUM A PARTIR DU CHLORURE DE POTASSIUM A L'AIDE D'UN ECHANGEUR D'ANIONS CHARGE D'IONS SULFATE. ON UTILISE COMME SOLUTION DE REACTION UNE SOLUTION SATUREE DE CHLORURE DE POTASSIUM QU'ON MET EN CONTACT, APRES SATURATION PAR LE SULFATE DE POTASSIUM, AVEC L'ECHANGEUR D'ANIONS FAIBLEMENT BASIQUE CHARGE D'IONS SULFATE, ON SEPARE L'ECHANGEUR D'ANIONS, ON SEPARE DE LA SOLUTION LES CRISTAUX FORMES ET ON REGENERE L'ECHANGEUR D'ANIONS EPUISE PAR CONTACT AVEC UNE SOLUTION DE SULFATE DE MAGNESIUMPROCESS FOR THE PREPARATION OF POTASSIUM SULFATE FROM POTASSIUM CHLORIDE USING AN ANION EXCHANGER CHARGED WITH SULFATE IONS. A SATURATED POTASSIUM CHLORIDE SOLUTION USED AS A REACTION SOLUTION, WHICH IS PUT INTO CONTACT, AFTER SATURATION BY POTASSIUM SULFATE, WITH THE LOW-BASIC ANION EXCHANGER CHARGED WITH SULFATE IONS, THE SEPARATOR IS SEPARATED ANIONS, SEPARATE FROM THE SOLUTION THE CRYSTALS FORMED AND REGENERATE THE EXCHANGED ANION EXCHANGER IN CONTACT WITH A MAGNESIUM SULFATE SOLUTION
