Abstract: The present invention relates to a gas-phase process for the preparation of butadiene comprising (i) providing a gas stream G-1 comprising ethanol; (ii) contacting the gas stream G-1 comprising ethanol with a catalyst, thereby obtaining a gas stream G-2 comprising butadiene, wherein the catalyst comprises a zeolitic material having a framework structure comprising YO2, Y standing for one or more tetravalent elements, wherein at least a portion of Y comprised in the framework structure is isomorphously substituted by one or more elements X, as well as to a zeolitic material having a framework structure comprising YO2, Y standing for one or more tetravalent elements, wherein at least a portion of Y comprised in the framework structure is isomorphously substituted by one or more elements X, wherein the zeolitic material displays a specific X-ray powder diffraction pattern, and to its use.
