Abstract
Disclosed is a method for producing adipamide, which may include the steps of: (a) reacting glucose, nitric acid (HNO), sodium nitrite (NaNO) and potassium hydroxide (KOH) to produce a glucaric acid potassium salt, (b) producing glucamide by reacting the glucaric acid potassium salt, with an acidic solution and removing a potassium ion from the glucaric acid potassium salt, (c) preparing an reaction admixture by adding the glucamide and a catalyst to hydrogen halide and acetic acid, and (d) treating the reaction admixture with hydrogen gas in a reactor thereby producing the adipamide.
