Abstract: Continuously operated process for the purification by distillation of the methanol used as solvent in the synthesis of propylene oxide by reaction of a hydroperoxide with propylene, with the methoxypropanols, as azcotrope with water, and the low boilers and high boilers simultaneously being separated off, wherein the solvent mixture obtained in the synthesis is fractionated in a dividing wall column.

Abstract: The invention relates to a method for producing an epoxide in the presence o f a zeolite catalyst, whereby (i) an alkene is reacted with a hydroperoxide in the presence of the catalyst in order to obtain the epoxide, and at least on e alkali metal salt is supplied to the reaction in at least one educt flow. Th e inventive method is characterised in that (ii) the supply of the at least on e alkali metal salt is cut off during the reaction, and the supply of hydroperoxide and alkene is continued.

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 obtained 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 one reaction between the propene and the hydroperoxide.
