Propylene is separated from the methanol present as a solvent in a crude olefin epoxidation product by means of an extractive distillation wherein a relatively heavy polar solvent having hydroxy groups such as water or propylene glycol is used as the extractive solvent. The method is also useful for removing water and impurities such as acetaldehyde from the propylene oxide.

Selon cette invention, on sépare le propylène du méthanol présent sous forme de solvant dans un produit d'époxydation oléfinique au moyen d'un processus de distillation extractive dans lequel un solvant polaire relativement lourd et possédant des groupes hydroxy tels que l'eau ou le propylène glycol est utilisé comme solvant extractif. Ce procédé est également utilisé pour éliminer l'eau et les impuretés telles que l'acétaldéhyde de l'oxyde de propylène.
