Juan Carlos Serrano-Ruiz and James A. Dumesic Catalytic Processing of Lactic Acid over Pt/Nb2O5 ChemSusChem 2
Aqueous solutions of lactic acid derived from biomass can be catalytically upgraded over Pt(0.1 %)/Nb2O5 into an organic phase rich in C4–C7 ketones that spontaneously separates from water. The single-reactor process retains 50 % of the feed carbon in the organic layer. The niobia support catalyzes CC coupling reactions and plays a key role in directing the synthesis towards these valuable products.
