Abstract
L'INVENTION EST RELATIVE A UN PROCEDE POUR LA PREPARATION DU PHOSPHATE MONOCACIQUE A PARTIR DE SUPERPHOSPHATE OU D'ACIDE PHOSPHORIQUE, LA SUBSTANCE DU PROCEDE EST LA SUIVANTE:A) ON PREPARE, A PARTIR DE SUPERPHOSPHATE, UNE SOLUTION DE PH = 1 - 2, D'UNE CONCENTRATION DE 40 A 55 % EN MASSE CONCERNANT SA TENEUR EN PHOSPHATE MONOCALCIQUE, ET QUI CONTIENT TROIS COMPOSES DISSOUS DANS L'EAU, A SAVOIR DU PHOSPHATE MONOCALCIQUE, DU DIPHOSPHATE DE CHAUX ET DE L'ACIDE PHOSPHORIQUE, AINSI QU'UN COMPOSE EN DISPERSION, A SAVOIR DU SULFATE DE CALCIUM. ENSUITE, EN ISOLE LE GYPSE PAR SEDIMENTATION, B) OU BIEN, A PARTIR D'ACIDE PHOSPHORIQUE, PAR L'ADDITION DE CARBONATE DE CALCIUM, ON PREPARE UNE SOLUTION CONTENANT DU PHOSPHATE MONOCALCIQUE, EN UNE CONCENTRATION DE 40 A 55 %, AINSI QUE DU PHOSPHATE MONOACIDE, DU DIPHOSPHATE DE CHAUX ET DE L'ACIDE PHOSPHORIQUE, PUIS, APRES ELIMINATION DE L'ARSENIC ET DES METAUX LOURDS, ON NEUTRALISE LA SOLUTION STOECHIOMETRIQUEMENT, EN EGARD AU PHOSPHATE MONOCALCIQUE, ET PAR SECHAGE, RESPECTIVEMENT PAR EVAPORATION, ON RECEUILLE LE PHOSPHATE MONOCALCIQUE DE LA SOLUTION AINSI OBTENUE.THE INVENTION RELATES TO A PROCESS FOR THE PREPARATION OF MONOCACIC PHOSPHATE FROM SUPERPHOSPHATE OR PHOSPHORIC ACID, THE SUBSTANCE OF THE PROCESS IS AS FOLLOWS: A) A SOLUTION OF PH = 1 - 2 IS PREPARED FROM SUPERPHOSPHATE , OF A CONCENTRATION OF 40 TO 55% IN MASS CONCERNING ITS MONOCALCIC PHOSPHATE CONTENT, AND WHICH CONTAINS THREE COMPOUNDS DISSOLVED IN WATER, INCLUDING MONOCALCIC PHOSPHATE, LIME DIPHOSPHATE AND PHOSPHORIC ACID, AS WELL AS A COMPOUND IN DISPERSION, TO KNOW CALCIUM SULFATE. THEN, ISOLATE THE GYPSUM BY SEDIMENTATION, B) OR WELL, FROM PHOSPHORIC ACID, BY THE ADDITION OF CALCIUM CARBONATE, A SOLUTION CONTAINING MONOCALCIC PHOSPHATE IS PREPARED, IN A CONCENTRATION OF 40 TO 55%, AS WELL AS MONOACID PHOSPHATE, LIME DIPHOSPHATE AND PHOSPHORIC ACID, THEN, AFTER ELIMINATION OF ARSENIC AND HEAVY METALS, NEUTRALIZE THE STOECHIOMETRICALLY SOLUTION, WITH RESPECT TO MONOCALCIC PHOSPHATE, AND BY DRYING, RESPECTIVOUSLY. THE MONOCALCIC PHOSPHATE OF THE SOLUTION SO OBTAINED.
