Abstract

Patente de Invenção <B>"SEPARAçãO DE METANOL E óXIDO DE PROPILENO A PARTIR DE UMA MISTURA DE REAçãO"<D> Propileno é separado a partir do metanol, presente como um solvente, em um produto de epoxidação de olefina bruto, por meio de uma destilação extrativa, em que um solvente polar relativamente pesado tendo grupos hidróxi, tal que água ou propileno glicol é usado como o solvente de extração. O processo também é útil para a remoção de água e de impurezas, tal como acetaldeído, a partir do óxido de propileno.
