Claims (1)

Patent-Anspruch:Patent claim: Das Semicarbazon C10 H17 N3 O kristallisiertThe semicarbazone C 10 H 17 N 3 O crystallizes 10 17 310 17 3 aus verdünntem Alkohol in glänzenden weißen Blättern. Es schmilzt bei etwa 167° unter Zersetzung.from diluted alcohol in glossy white leaves. It below melts at about 167 ° Decomposition. Statt der Ketopinsäure kann man auch ihre Derivate, wie die Bromketopinsäure vom Schmelzpunkt i8i° (Beilstein L, Ergänzungsband, S. 266), verwenden.Instead of ketopic acid, you can also use its derivatives, such as bromoketopic acid from Melting point 18 ° (Beilstein L, supplementary volume, P. 266).
