Abstract
The invention relates to a process for the production of 1,3-butadiene from a feed comprising ethanol and acetaldehyde in the presence of a supported tantalum catalyst obtainable by aqueous impregnation of the support with a water-soluble tantalum precursor. Furthermore, the present invention relates to a process for the production of a supported tantalum catalyst, and the supported tantalum catalyst. Finally, the invention relates to the use of the supported tantalum catalyst for the production of 1,3-butadiene from a feed comprising ethanol and acetaldehyde to increase one or both of selectivity and yield of the reaction.
