    Abstract: The invention relates to a method for producing propylene oxide, comprising at least the following steps: (a) propene is reacted with a hydroperoxide in a solvent in the presence of a zeolite catalyst, in order to obtain a mixture (G0), said mixture (G0) containing propylene oxide, solvent, non-reacted propene, non-reacted hydroperoxide and oxygen; (b) the propylene oxide is separated from the mixture (G0) in such a way that a mixture (G1) is obtaine d which comprises non-reacted propene and oxygen; (c) the mixture (G1) is brought into contact with a liquid medium containing at least solvent, in order to obtain the mixtures (G2) and (G3), said mixture (G3) containing a part of the non-reacted propene and oxygen, and said mixture (G2) containing the solvent and the rest of the propene, the separated mixture (G3) of non- reacted propene and oxygen having a ratio of oxygen to propene which renders the mixture (G3) non-inflammable, and the mixture (G2) supplying at least on e reaction between the propene and the hydroperoxide.
