Description

  

  Verfahren zur Herstellung eines     Aminodiphenylaminderivates.       Vorliegendes Patent bezieht sich auf -ein  Verfahren zur Herstellung eines     Aminodi-          phenylaminderivates,    dadurch gekennzeichnet,  dass man     Nitrosobenzol    mit     o-Nitrosoanisol     kondensiert und das Kondensationsprodukt  mit einem Reduktionsmittel behandelt.  



  Die bisher nicht bekannte Base schmilzt       naeh    dem Reinigen über das Chlorhydrat und.       Umkristallisieren    aus Benzol bei 87  . Sie  soll als Zwischenprodukt zur Herstellung von       Farbstoffen    verwendet werden.  



  Da die Base mit dem nach den Berichten  der deutschen chemischen Gesellschaft,     Bd.    42,  Seite 1083, erhaltenen     Aminomethogydiphenyl-          amin    nicht identisch ist, bleibt für dieselbe  nur die Konstitution eines     4-Amino-3-meth-          ogydiphenylamins    übrig.    <I>Beispiel:</I>    Eine Lösung von 53,5 Teilen     Nitroso-          benzol    und 68,5 Teilen     o-Nitrosoanisol    in    300 Teilen Eisessig wird in     21s    Stunden in  1500 Teile Schwefelsäure von 66       Be    bei  0-5       eintropfen    gelassen.

   Durch Eingiessen  der Lösung in Kochsalzlösung wird das er  haltene Kondensationsprodukt ausgefällt. Es  schmilzt bei     1531.    Es wird noch feucht in  3000 Teilen Wasser und 65 Teilen Ätz  natronlauge von 38       Be    gelöst und bei 60    mit einer Lösung von<B>175</B> Teilen     gesehmol-          zenem    Schwefelnatrium in Wasser versetzt  und eine halbe Stunde auf 80   erwärmt,  wobei unter Hellfärbung der Lauge die Base  als helles<B>Öl</B> ausfällt, das     beim    Abkühlen  erstarrt und dann     abgesaugt    und ausge  waschen wird.



  Process for the preparation of an aminodiphenylamine derivative. The present patent relates to a process for the preparation of an aminodiphenylamine derivative, characterized in that nitrosobenzene is condensed with o-nitrosoanisole and the condensation product is treated with a reducing agent.



  The previously unknown base melts after cleaning over the chlorohydrate and. Recrystallize from benzene at 87. It is intended to be used as an intermediate in the manufacture of dyes.



  Since the base is not identical to the aminomethogydiphenylamine obtained according to the reports of the German Chemical Society, vol. 42, page 1083, only the constitution of a 4-amino-3-methogydiphenylamine remains for the same. <I> Example: </I> A solution of 53.5 parts of nitrosobenzene and 68.5 parts of o-nitrosoanisole in 300 parts of glacial acetic acid is allowed to drip into 1500 parts of sulfuric acid of 66 Be at 0-5 in 21s hours.

   The condensation product obtained is precipitated by pouring the solution into saline solution. It melts at 1531. While still moist, it is dissolved in 3000 parts of water and 65 parts of caustic soda solution of 38 Be and, at 60, a solution of 175 parts of salted sulfuric sodium in water is added and it is increased for half an hour 80 heated, whereby the base precipitates as a light <B> oil </B> with a light coloration of the lye, which solidifies on cooling and is then suctioned off and washed out.

PATENT APPLICATION Process for the production of an aminodiphenylamine derivative, characterized in that nitrosobenzene is condensed with o-nitroso anisole and the condensation product is treated with a reducing agent. After cleaning, the base melts via the chlorohydrate and recrystallizes from benzene at <B> 870. </B> It is intended to be used as an intermediate in the manufacture of dyes. Da die Base mit dem nach den Berichten der deutschen chemischen Gesellschaft, Bd. 42, Seite 1083, erhaltenen Aminomethoxy di- phenyiamin nicht identisch ist, bleibt für dieselbe nur die Konstitution eines 4-Amirro- 3-methoxydiphenylamirrs übrig. Since the base is not identical to the aminomethoxy diphenyiamine obtained according to the reports of the German Chemical Society, Vol. 42, page 1083, only the constitution of a 4-Amirro-3-methoxydiphenylamine remains for it.
