Title (EN) METHODS FOR THE SEPARATION OF HCL FROM A CHLORIDE SALT AND COMPOSITIONS PRODUCED THEREBY
(FR) PROCÉDÉS DE SÉPARATION DE HCl D'UN SEL DE CHLORURE ET COMPOSITIONS AINSI PRODUITES
Abstract:
(EN) The present invention provides an organic phase composition comprising (f) a first solvent (S1) characterized by water solubility of less than 10% and by at least one of (a1) having a polarity related component of Hoy's cohesion parameter (delta-P) between 5 and 10 MPa1/2 and (b1) having a Hydrogen bonding related component of Hoy's cohesion parameter (delta-H) between 5 and 20 MPa1/2; (g) a second solvent (S2) characterized by water solubility of at least 30% and by at least one of (a2) having a delta-P greater than 8 MPa1/2 and (b2) having a delta-H greater than 12 MPa1/2; (h) water (i) HCI, and (j) a chloride salt.
(FR) L'invention concerne une composition à phase organique comprenant (f) un premier solvant (S1) caractérisé par une hydrosolubilité inférieure à 10% et par au moins (a1) un paramètre de cohésion de Hoy caractérisant pour un constituant donné l'énergie correspondant aux interactions polaires existant entre les molécules de ce constituant (delta p) compris entre 5 et 10 MPa1/2 ou (b1) un paramètre de cohésion de Hoy caractérisant pour un constituant donné l'énergie correspondant aux interactions de type liaisons hydrogène existant entre les molécules de ce constituant (delta h) compris entre 5 et 20 MPa1/ 2, (g) un deuxième solvant (S2) caractérisé par une hydrosolubilité d'au moins 30% et par au moins (a2) un delta p supérieur à 8 MPa1/2 ou (b2) un delta h supérieur à 12 MPa1/2, (h) de l'eau, (i) HCI et (j) un sel de chlorure.
