Abstract
A process is provided for producing adipic acid from a renewable resource, i.e., biomass. The process comprises: hydrolyzing the renewable resource to provide 5-hydroxymethylfurfural, hydrogenating the 5-hydroxymethylfurfural in the presence of a catalyst to provide 2, 5-tetrahydrofurandiomethanol, treating the 2, 5-tetrahydrofurandiomethanol with hydrogen in the presence of a catalyst to provide 1, 6 hexanediol, and oxidizing the 1, 6 hexanediol in the presence of a microorganism to provide adipic acid. The formation of the adipic acid is provided with the microorganism of Gluconobacter oxydans subsp. oxydans. The renewable resources are wastes selected from the group consisting of paper, wood, corn stalks, and logging residues.
