Title
(EN) PROCESS TO SEPARATE RHODIUM FROM AN ORGANIC MIXTURE
(FR) PROCEDE DE SEPARATION DE RHODIUM D'UN MELANGE ORGANIQUE
Abstract
(EN) Process to separate rhodium from an organic starting mixture comprising of an organic solvent, C6-dicarboxylic acids and iodide compounds, wherein rhodium is separated by extracting the organic starting mixture with an aqueous solvent containing C6-dicarboxylic acids and an iodide compound resulting in an organic raffinate poor in rhodium and an aqueous extract rich in rhodium.
(FR) Cette invention a trait à un procédé permettant de séparer du rhodium d'une substance organique de départ constituée d'un solvant organique, d'acides dicarboxyliques comportant 6 atomes de carbone et de composés d'iodure. On procède à cette séparation par extraction du mélange organique de départ à solvant aqueux contenant des acides dicarboxyliques comportant 6 atomes de carbone et des composés d'iodure, ce qui donne lieu à un raffinat organique pauvre en rhodium ainsi qu'à un extrait aqueux riche en rhodium.
