Description

  

  Verfahren zur Darstellung einer halogensubstituierten     Acylaminosulfonsäure.            Gegenstand    des     vorliegenden        Patentes    ist  ein Verfahren zur     Herstellung    einer     chlor-          substituierten        Acylaminosulfonsäure,    da  durch gekennzeichnet, dass man     N,N'-bis-(4-          (6'-        Methylphenoxyl    - 6 -     sulf    o-     phenyl)

      -     harn-          stoff    als     Natriumsalz    in     Waeser    gelöst, chlo  riert. Die neue Verbindung, die     zirka,     4 Atome Chlor im Molekül enthält,     bildet     eine     krümelige,        braune    Masse und eignet sich  zur     Verwendung    als     Mottenschutzmittel.     



  <I>Beispiel:</I>  12     Teile    des     N,N'-bis-(4-[6'-Methylphen-          oxyl    - 6 -     sulfo-phenyl)-harnstoffes,    erhältlich  aus     6'-Methyl-4-amino-1,1'-diphenyläther-2-          sulfonsäure    und     Phosgen,    werden mit ,der be  rechneten     Sodamenge    in 1'00 Teilen Wasser  gelöst und Chlor bei     60--45          eingeleitet,    wo-    bei man     ,

  durch        Zutropfen    von Natronlauge  für     dauernd        alkalische        Reaktion    sorgt. Nach  zwei Stunden wird das chlorierte Produkt  mit     @Salzsäure    gefällt und als     krümelige,     bräunliche Masse erhalten, die 34,6% ge  bundenes Chlor enthält.



  Process for the preparation of a halogen-substituted acylaminosulfonic acid. The present patent relates to a process for the preparation of a chlorine-substituted acylaminosulfonic acid, characterized in that N, N'-bis (4- (6'-methylphenoxyl - 6 - sulfo-phenyl)

      - urea dissolved in water as the sodium salt, chlorinated. The new compound, which contains around 4 atoms of chlorine in the molecule, forms a crumbly, brown mass and is suitable for use as a moth repellent.



  <I> Example: </I> 12 parts of the N, N'-bis (4- [6'-methylphenoxyl - 6 - sulfo-phenyl) urea, obtainable from 6'-methyl-4-amino- 1,1'-Diphenylether-2-sulfonic acid and phosgene are dissolved with the calculated amount of soda in 1'00 parts of water and chlorine is passed in at 60-45, whereby,

  Provides a permanent alkaline reaction by adding caustic soda. After two hours, the chlorinated product is precipitated with hydrochloric acid and obtained as a crumbly, brownish mass containing 34.6% combined chlorine.
