The reasons for the deactivating effect of water on the conversion of ethanol to 1,3-butadiene in the presence of Zn-Zr(La)-Si oxide and Cu(Ag, Zn)/Ta/SiBEA zeolite catalysts are studied. The decrease in the yield of 1,3-butadiene using ethanol–water mixtures of different composition compared with rectified ethanol is due to the deactivating effect of H2O vapor on the Lewis acid sites of the catalyst, at which acetaldehyde undergoes aldol condensation.
