Abstract
A method for preparing bio adipic acid includes steps of (a) preparing a glucaric acid potassium salt by mixing and reacting glucose, nitric acid (HNO), sodium nitrite (NaNO) and potassium hydroxide (KOH), (b) preparing glucamide from the glucaric acid potassium salt prepared in the step (a), (c) preparing 2,4-hexadiene diamide by performing a deoxydehydration reaction on the glucamide prepared in the step (b), (d) preparing adipamide by introducing the 2,4-hexadiene diamide prepared in the step (c), hydrogen and a hydrogenation catalyst to a reactor and performing a hydrogenation reaction, and (e) preparing adipic acid by introducing the adipamide prepared in the step (d) and an aqueous hydrochloric acid solution to a reactor and then performing a hydrolysis reaction at a specific temperature.
