- KAISERLICHESi PATENTAMT.\%Nach den Angaben der Patentschrift No. 58204 ist die Gewinnung des symmetrischen Diamidodiphenylthioharnstoffes durch Einwirkung von Schwefelkohlenstoff auf p-Phenylendiamin nicht nur in alkoholischer oder ätherischer Lösung möglich, sondern in jedem indifferenten Medium, in welchem die zur Reaction gelangenden Körper löslich sind. Insbesondere eignen sich als solche aufser den oben erwähnten noch Methylalkohol, Amylalkohol, Chloroform und Aceton, ohne jedoch vor jenen Vortheil zu bieten.Die Ausführung der Reaction bei Anwendung dieser Solventien weicht im übrigen von dem in dem Patent No. 58204 gegebenen Beispiel nicht ab.Pateντ-Anspruch:Verfahren zur Darstellung von symmetrischem Diamidodiphenylthioharnstoff, darin bestehend, dafs man in dem Verfahren des Haupt-Patentes an Stelle von Alkohol oder Aether andere indifferente Lösungsmittel, wie Methylalkohol, Amylalkohol, Chloroform, Aceton., anwendet.
