US 9,434,709 B2 · Production of adipic acid and derivatives from carbohydrate-containing materials

Abstract

The present invention generally relates to processes for the chemocatalytic conversion of a glucose source to an adipic acid product. The present invention includes processes for the conversion of glucose to an adipic acid product via glucaric acid or derivatives thereof. The present invention also includes processes comprising catalytic oxidation of glucose to glucaric acid or derivative thereof and processes comprising the catalytic hydrodeoxygenation of glucaric acid or derivatives thereof to an adipic acid product. The present invention also includes products produced from adipic acid product and processes for the production thereof from such adipic acid product.

Dependent claims

A process for 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 wherein at least about 50% of the glucose is converted to glucaric acid or lactone thereof.

Dependencies are inferred from the claim text.
