    摘要： The present invention relates to the manufacture of solid materials or shaped bodies containing at least one zeolite and being at least partly crystalline. Furthermore, the present invention relates to the solid materials or shaped bodies as such and to the use of these materials for reactions of compounds having at least one C—C double bond with at least one hydroperoxide. Specifically, the present invention relates to a process for the manufacture of a solid material containing at least one zeolite and being at least partly crystalline, wherein the synthesis of the said solid material involves at least one partial step of contacting at least one transition metal oxide source with at least one epoxide or hydrolysate thereof prior to or during the at least partial crystallization of said solid material.

    摘要： The invention relates to a method for continuously returning an olefin which has not been reacted with hydroperoxide in order to form oxiranes during the epoxidation of olefins. Said olefin is contained in the flow of waste gas which is produced during epoxidation. Said method is characterised by the following steps: (i) compressing and cooling the flow of waste gas, (ii) separating the olefin from the flow of waste gas obtained in step (i) by distillation,(iii) epoxidating the olefin separated in (ii) with hydroperoxide.
