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.
