Title (EN) WATER MISCIBLE SOLVENT BASED PROCESS FOR PURIFYING A BISPHOSPHATE
(FR) PROCÉDÉ À BASE DE SOLVANT MISCIBLE DANS L'EAU POUR PURIFIER UN DIPHOSPHATE
Abstract:
(EN) There is provided herein a process for purifying bisphosphate comprising solvating a molten bisphosphate in a mixture of water and water miscible solvent; cooling the solution over a period and to a temperature that provides for crystallization of solid product; increasing the pH of the solution prior to, and/or during, and/or after the initiation of crystallization, and/or after crystallization, by the addition of a base; and after crystallization is complete, separating solid product from the solution; washing the separated solid product in the same and/or different mixture of water and water miscible solvent; and, washing the solid product which has been washed in the mixture with water.
(FR) La présente invention concerne un procédé permettant de purifier un diphosphate et consistant à solvater un diphosphate fondu dans un mélange d'eau et de solvant miscible dans l'eau; à refroidir la solution pendant un certain temps jusqu'à une température permettant la cristallisation d'un produit solide; à faire remonter le pH de la solution par adjonction d'une base, avant, et/ou pendant, et/ou après le début de la cristallisation, et/ou après cristallisation, et après achèvement de la cristallisation, à séparer de la solution le produit solide; à laver le produit solide séparé dans le même mélange et/ou dans un mélange différent d'eau et de solvant miscible dans l'eau; et enfin à laver à l'eau le produit solide qui a été lavé dans le mélange.
