Abstract

La présente invention concerne le domaine de la séparation et de la purification des carboranes à partir de mélanges contenant des substances goudronneuses. Le procédé de l'invention consiste à enlever du mélange précite, sauf dans certains cas, tout solvant dans lequel le carborane a été synthétisé, à dissoudre ensuite ledit mélange dans un premier solvant dans lequel tous les constituants de ce mélange sont solubles et ne réagissent pas avec ce mélange, à extraire le carborane dudit mélange au moyen d'un second solvant, non miscible aux solvants précités et dans lequel ledit carborane est soluble et les produits goudronneux précités insolubles, et finalement à récupérer le carborane à partir dudit second solvant. L'invention permet d'obtenir des carboranes de pureté élevée, atteignant par exemple 95-97 %.
