The production of bulk chemicals and fuels from renewable bio-based feedstocks is of significant importance for the sustainability of human society. Adipic acid, as one of the most-demanded drop-in chemicals from a bioresource, is used primarily for the large-volume production of nylon-6,6 polyamide. It is highly desirable to develop sustainable and environmentally friendly processes for the production of adipic acid from renewable feedstocks. However, currently there is no suitable bio-adipic acid synthesis process. Demonstrated herein is the highly efficient synthetic protocol for the conversion of mucic acid into adipic acid through the oxorhenium-complex-catalyzed deoxydehydration (DODH) reaction and subsequent Pt/C-catalyzed transfer hydrogenation. Quantitative yields (99 %) were achieved for the conversion of mucic acid into muconic acid and adipic acid either in separate sequences or in a one-step process. Taking a dip: A highly efficient synthetic protocol has been developed for the conversion of mucic acid into adipic acid by the oxorhenium-complex-catalyzed deoxydehydration reaction and subsequent Pt/C-catalyzed transfer hydrogenation. Quantitative yields were achieved for the conversion of mucic acid into muconic acid and adipic acid esters either through separate sequences or through a one-pot process.

The present invention provides a method for synthesizing an aliphatic polycarboxylic acid, the method comprising the steps of: (a) dehydrating a polyhydroxycarboxlic acid using a rhenium-based catalyst to produce an unsaturated polycarboxylic acid precursor; and (b) performing a hydrogenation reaction on the unsaturated polycarboxylic acid precursor to produce the aliphatic polycarboxylic acid.
