Abstract
A process in continuous is described for the preparation of oxides of olefins by the direct epoxidation of an olefin with hydrogen peroxide, or compounds capable of producing hydrogen peroxide under the reaction conditions, in a solvent medium, in the presence of a catalytic system consisting of a zeolite containing titanium and a nitrogenated organic base having formula (I).The process allows the production of high conversions and selectivities of the olefin into the corresponding oxide with a stable catalytic activity over a period of time.
