Title (EN) METHOD FOR SELECTIVE DISSOLUTION USING A NON-IONIC SURFACTANT
(FR) PROCÉDÉ DE DISSOLUTION SÉLECTIVE UTILISANT UN AGENT TENSIOACTIF NON-IONIQUE
Abstract:
(EN) The present invention relates to a method for selective dissolution of a first solid compound present in a mixture with respect to at least one second solid compound different from said first solid compound, also present in said mixture, wherein said method comprises at least one step consisting in bringing said mixture into contact with a dissolving solution in which said first solid compound is dissolved, generating at least one gaseous compound, and in which said second solid compound is dissolved without generating any gaseous compound, said dissolving solution comprising at least one non-ionic surfactant.
(FR) La présente invention concerne un procédé de dissolution sélective d'un premier composé solide présent dans un mélange vis-à-vis d'au moins un second composé solide différent dudit premier composé solide également présent dans ledit mélange, ledit procédé comprenant au moins une étape consistant à mettre en contact ledit mélange avec une solution de dissolution dans laquelle ledit premier composé solide est dissous en générant au moins un composé gazeux et dans laquelle ledit second composé solide est dissous sans générer aucun composé gazeux, ladite solution de dissolution comprenant au moins un agent tensioactif non ionique.
