<p>Disclosed herein are processes for the chemocatalytic conversion of a glucose source to an adipic acid product of formula II wherein R1 and X are defined in the specification. The process comprises reacting a hydrodeoxygenation substrate of formula I, such as glucaric acid, and hydrogen gas in the presence of a hydrodeoxygenation catalyst and a halogen source. In one embodiment the hydrodeoxygenation catalyst comprises a first metal selected from Ru, Rh, Pd, Pt, and combinations thereof and a second metal selected from Mo, Ru, Rh, Pd, Ir, Pt, and Au. Additionally disclosed are products produced from the adipic acid products and processes for the preparation thereof. Additionally disclosed is a process of preparing glucaric acid or lactone thereof, the process comprising: reacting glucose with oxygen in the presence of a heterogeneous oxidation catalyst comprising a metal selected from the group consisting of Pd, Pt, and a combination thereof to convert at least a portion of the glucose to glucaric acid or lactone thereof, wherein the pH of the reaction mixture is less than 7 and the reaction is conducted in the substantial absence of added base, and at least 50% of the glucose is converted to glucaric acid or lactone thereof.</p> |
