“…Rennovia also disclosed a patent for the conversion of glucose to adipic acid, involving selective catalytic aerobic oxidation of glucose to glucaric acid in water (66% yield over Pt/SiO 2 ), that further undergoes hydrodeoxygenation to adipic acid in acetic acid using PdRh/SiO 2 and a halogen source (89% yield) [24,25]; the process is currently in its development stage. Several companies (Verdezyne, BioAmber, Genomatica among others) are developing fermentation routes of glucose or fatty acids to adipic acid [26]. Combined biological-chemical processes have also been proposed using the carbohydrate fractions of lignocellulosic biomass as feedstock [27][28][29][30].…”

Hexanediol is an emerging building-block chemical, which may be derived from biomass and can produce adipic acid for the synthesis of polymers. A series of supported Pt, Bi-Pt, Au, Pd, Au-Pd, and Au-Pt catalysts were prepared and evaluated in the aerobic oxidation of 1,6-hexanediol to adipic acid in aqueous solution without the addition of a base or an acid. The influences of various molar ratios of the metals in the bimetallic systems and the support (C, ZrO 2) were studied. Under the conditions used, bismuth did not promote the catalytic performance of Pt catalysts. On the other hand, formation of an alloy of Au-Pd or Au-Pt made the catalysts very effective. A yield of adipic acid of ca. 96% was achieved at 70 °C under 40 bar of air over the Au-Pt catalyst supported on zirconia with a Au/Pt molar ratio of about 1. Recycling tests revealed the possibility to use the catalyst up to 6 times without significant changes in its catalytic performance.
