Abstract
A method of producing adipic acid using glucose as a starting material, in which adipic acid is finally obtained via an alkyl adipate intermediate from a glucaric acid potassium salt.
Claims16
A method of producing adipic acid, comprising:
- obtaining a reaction solution by mixing a glucaric acid potassium salt, a solvent, an acid catalyst, and a catalyst for deoxydehydration;
- obtaining alkyl adipate by adding hydrogen gas to the reaction solution and performing a deoxydehydration (DODH) reaction;
- and
- obtaining adipic acid by mixing the alkyl adipate with an acid solution and performing a hydrolysis reaction.
