PROCESS FOR PRODUCING PROPYLENE OXIDE

摘要

The present invention relates to a process for producing propylene oxide comprising (I) reacting propene with hydrogen peroxide in the presence of a catalyst to give a mixture (Gl) comprising propylene oxide, unreacted propene, and oxygen; (II) separating propylene oxide from mixture (Gl) to give a mixture (GII) comprising propene and oxygen; (III) reducing the oxygen comprised in mixture (GII) at least partially by reaction with hydrogen in the presence of a catalyst comprising Sn and at least one noble metal.
