Abstract: Continuous process for the epoxidation of olefins by means of hydroperoxide, in which the epoxidation is carried out in a reactor in which at least one catalyst suspended in a liquid phase is present, wherein the liquid phase is passed through a device which has openings or channels and is installed in the reactor and the epoxide-containing liquid is separated off by means of crossflow filtration so that the suspended catalyst is retained in the reaction system.

Abstract: Process for the continuous recirculation of the olefin which has not been reacted in the epoxidation of olefins by means of hydroperoxide to give oxiranes and is present in the offgas stream formed during the epoxidation, which comprises the steps (i) to (iii) (i) compressing and cooling the offgas stream, (ii) seperating the olefin from the offgas stream obtain in step (i) by distillation, (iii) epoxidizing the olefin seperating off in step (ii) by means of hydroperoxide.

Abstract: A method for the production of propylene oxide (PO) by reacting propene with a hydroperoxide in a nitrile-containing solvent in presence of a porous oxide-containing catalyst, involves using a zeolite catalyst with an X-ray crystal structure of the MWW type. An independent claim is also included for formed catalyst bodies containing the above type of zeolite.

Abstract: A process for the preparation of an epoxide in the presence of a zeolite catalyst, in which (i) an alkene is reacted with a hydroperoxide in the presence of the catalyst to obtain the epoxide, at least one alkali metal salt being fed into the reaction in at least one precursor stream, wherein (ii) during the reaction the addition of the at least one alkali metal salt is stopped and hydroperoxide and alkene are still fed into the reaction.

Abstract: Ferromagnetic chromium dioxide is prepared by converting oxides of trivalent and hexavalent chromium under superatmospheric pressure and at elevated temperatures in the presence of water and with the addition of an antimony compound as a modifier and, if required, further additives in an amount of not more than 15% by weight, by a method in which the antimony compound is present in the form of a water-soluble salt whose anion contains one or more organic molecular moieties which are oxidized in concentrated chromic acid.
