Title
(EN) A METHOD FOR THE SEPARATION OF A NON-VOLATILE STRONG ACID FROM A SALT THEREOF AND COMPOSITIONS PRODUCED THEREBY
(FR) PROCÉDÉ POUR SÉPARER UN ACIDE FORT NON VOLATIL D'UN SEL DE CE DERNIER 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 a water solubility of at least 30% and by at least one of (a2) having delta-P greater than 8 MPa1/2 and (b2) having delta-H greater than 12 MPa1/2; (h) water (i) a non-volatile strong acid, and (j) a salt thereof.
(FR) La présente invention concerne une composition en phase organique comprenant (f) un premier solvant (S1) caractérisé par une solubilité dans l'eau inférieure à 10% et par le fait qu'il présente (a1) une composante liée à la polarité (delta-P) du paramètre de cohésion de Hoy comprise entre 5 et 10 MPa1/2 et/ou (b1) une composante liée aux liaisons hydrogène (delta-H) du paramètre de cohésion de Hoy comprise entre 5 et 20 MPa1/2; (g) un deuxième solvant (S2) caractérisé par une solubilité dans l'eau d'au moins 30% et par le fait qu'il présente (a2) un delta-P supérieur à 8 MPa1/2 et/ou (b2) un delta-H supérieur à 12 MPa1/2; (h) de l'eau, (i) un acide fort non volatil, et (j) un sel de ce dernier.
