Patent

CA 2499055

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.

Cette invention, qui a trait à la fabrication de matériaux solides ou de corps formés contenant au moins une zéolithe et qui sont, au moins partiellement, cristallins, concerne également des matériaux solides ou des corps formés ainsi que l'usage qui en est fait dans des réactions de composés ayant au moins une double liaison carbone-carbone avec au moins un hyperoxyde. Elle porte plus précisément sur la fabrication d'un matériau solide contenant au moins une zéolithe et qui est, au moins partiellement, cristallin. La synthèse de ce matériau solide comporte au moins une étape partielle consistant à mettre en contact au moins une source d'oxyde de métal de transition avec au moins un groupe époxyde ou un hydrolysat de celui-ci et ce, avant ou pendant la cristallisation partielle du matériau solide.
