Zusammenfassung:The present invention relates to a process for the resolution of two enantiomers which consists in inducing the preferential crystallization of one enantiomer by adjusting the composition of a suspension or solution including a racemic mixture of the two enantiomers and a solvent, by evaporation of the latter. La présente invention concerne un procédé de résolution de deux énantiomères qui consiste en l'induction de la cristallisation préférentielle d'un énantiomère par ajustement de la composition d'une suspension ou d'une solution comprenant un mélange racémique des deux énantiomères et d'un solvant, par évaporation de ce dernier.
