Abstract (en)

[origin: WO0220503A1] The invention relates to a method for producing an epoxide in the presence of 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 one alkali metal salt is supplied to the reaction in at least one educt flow. The inventive method is characterised in that (ii) the supply of the at least one alkali metal salt is cut off during the reaction, and the supply of hydroperoxide and alkene is continued.
