Claims (2)

Patent-Ansprüche:
1. Abänderung des durch Patent 184496 geschützten Verfahrens zur Darstellung von Thionaphthenderivaten, darin bestehend, daß man hier zwecks Gewinnung der 3-Amino-i-thionaphthen-2-carbonsäure die zur Verseifung der o-Cyanphenylthioglykolsäure benutzten Ätzalkalien in soleher Konzentration anwendet, daß die entstehende 3 - Amino-i-thionaphthen-2-carbonsäure in Form der Alkalisalze aus der Reaktionsmasse auskristallisiert.
2. Abänderung des durch Patent 184496 geschützten Verfahrens zur Darstellung von Thionaphthenderivaten, darin bestehend, daß man hier zwecks Gewinnung des 3-Oxy-r-thionaphthens die 3-Aminoi-thionaphthen-2-carbonsäure mit Säuren behandelt.
