Abstract:
The present invention relates to a process for the production of butadiene by condensation of ethanol using a catalyst containing sillica-supported elements from group 3A and group 4B of the periodic table. The catalyst of the present invention has high activity and selectivity to butadiene in the synthesis reaction of said olefin from ethanol.
