A mixture of materials having different boiling points is separated into fractions having different boiling points. The separated fraction containing the desired product is stripped using the vapors of a lower boiling fraction. The process of the present invention is particularly useful for recovering a desired isomer or isomer mixture from a technical mixture obtained during production of an aromatic amine such as toluenediamine. Little or no unwanted isomer or by-product is present in the isomer or isomer or isomer mixture product of this process.

L'invention concerne un mélange de matériaux ayant des points d'ébullition différents. Ledit mélange est séparé en fractions ayant des points d'ébullition différents. La fraction contenant le produit recherché est enlevée au moyen des vapeurs d'une fraction à point d'ébullition inférieure. Le procédé selon l'invention est particulièrement utile pour récupérer un isomère ou un mélange d'isomère recherché dans un mélange technique obtenu lors de la production d'une amine aromatique telle que la toluènediamine. Peu ou pas d'isomère ou de sous-produit est présent dans l'isomère ou le produit du mélange d'isomère obtenu suivant ledit procédé.
