| titleOfInvention | Integrated process for the preparation of epoxides |
| abstract | The present invention relates to an integrated process for the preparation in continuous of epoxides which comprises: (a) preparing an alcoholic or hydro-alcoholic solution of hydrogen peroxide in a concentration of over 3% by weight, using a gaseous stream containing hydrogen, oxygen and an inert gas, in the presence of a bimetallic catalyst based on palladium and platinum as active components; (b) putting the alcoholic or hydro-alcoholic solution of hydrogen peroxide obtained in step (a) in contact with an olefin and a buffering agent, in the presence of an epoxidation catalyst suspended in the reaction solvent, in order to obtain a reaction mixture containing the epoxide corresponding to the olefin, water and the alcoholic solvent; (c) treating the alcoholic stream leaving step (b), after separation of the epoxide, in order to eliminate the nitrogenated compounds present; (d) feeding the alcoholic solvent obtained in (c) to step (a). A part of the solvent obtained in (c) can be used, when necessary, for diluting the hydro-alcoholic solution of hydrogen peroxide obtained in step (a) to the value required by the epoxidation plant. The process operates under high safety conditions and with a high overall efficiency, in terms of productivity and selectivity. |
