Abstract

We report the direct production of 1,3-butadiene from the dehydration of 2,3-butandiol by using alumina as a catalyst. Under optimized kinetic reaction conditions, the production of methyl ethyl ketone and isobutyraldehyde, formed via the pinacol-pinacolone rearrangement, was markedly reduced and over 80% selectivity to 1,3-butadiene and 3-buten-2-ol could be achieved. The presence of water plays a critical role in the inhibition of oligomerization.The amphoteric nature of ϒ- Al2O3 was identified as important and this contributed to the improved catalytic selectivity when compared with other acidic catalysts.
