Disclosed is a method for producing adipamide, which may include the steps of: (a) reacting glucose, nitric acid (HNO
3
), sodium nitrite (NaNO
2
) and potassium hydroxide (KOH) to produce a glucaric acid potassium salt, (b) producing glucamide by reacting the glutaric 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.

wurde mit Distickstofftetroxyd oxydiert. Aus den Oxydationsprodukten konnten kristallisierte Derivate der D-Zuckersäure und des β-Methyl-D-glucuro-pyranosids isoliert werden. Das kristallisiertere β-Methyl-glucuronid wurde als Amid und Hydrazid charakterisiert und mit Perjodsäure abgebaut. Die Pyranosid-Struktur des β-Methyl-glucuronids wurde sichergestellt.
