Abstract
L'invention concerne un procédé de séparation extractive de thallium trivalent et de thallium monovalent On met en contact un milieu aqueux, contenant T1**+3 et T1**+1, éventuellement en présence d'un acide alcanoïque 1-5 C avec un solvant organique peu soluble dans l'eau et pouvant dissoudre l'acide alcanoïque afin de faire passer au moins une partie de T1**+3 par extraction préférentielle dans la phase organique, et l'on recueille a un solvant organique contenant T1**+3 extrait et b une phase aqueuse contenant T1**+1 e appauvri en T1** +3. L'extracteur peut comprendre un acide carboxylique ou un solvant organique inerte et non acide. Application du carboxylate de T1**+3 obtenu : époxydation d'oléfines.
