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: 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: Se da a conocer un proceso continuo para la epoxidacion de olefinas, por medio de hidroperoxidos, en el cual la epoxidacion se lleva a cabo en un reactor, en el cual al menos esta presente un catalizador suspendido en una fase liquida, en que esta fase liquida es pasada a traves de un dispositivo, el cual tiene aberturas o canales, y se instala dentro del reactor, y el liquido que contiene epoxido se separa y aleja por medio de la filtracion de flujo transversal, de manera que dicho catalizador suspendido sea retenido en el sistema de reaccion.
