Title
(EN) PROCESS IMPROVEMENT USING SOLUBILITY CHARACTERISTICS
(FR) AMELIORATION DE TRAITEMENT UTILISANT LES CARACTERISTIQUES DE SOLUBILITE
Abstract
(EN)
The present invention is directed to a process of maximizing the solubility of a nonelectrolyte solute in a solvent by operating within an optimal temperature range at conditions wherein the nonelectrolyte solute is not a pure liquid. In particular, the process of the present invention is directed to conversion of a carboxylic acid compound to an ester under conditions wherein the solubility of the ester in an alcoholic solvent approaches ideal solubility behavior.
(FR)
La présente invention concerne un procédé permettant de maximiser la solubilité d'un soluté non électrolyte dans un solvant en opérant dans une plage de températures optimale dans des conditions où le soluté non électrolyte n'est pas un liquide pur. L'invention concerne plus particulièrement un procédé de conversion d'un composé d'acide carboxylique en un ester dans des conditions où la solubilité de l'ester dans un solvant alcoolique confine au comportement de solubilité idéal.
