Description

  

  Verfahren zur Darstellung einer halogensubstituierten     Acylaminosulfonsäure.            Gegenstand        des        vorliegenden        Zueatz-          patentes    ist ein Verfahren zur     Herstellung     einer     halogensubstituierten        Acylaminosulfon-          säure,    dadurch gekennzeichnet, dass man  3'-     Aminobenzoyl    - 3,4     --diohlorauiliu-6-sulfon        -          säure    mit     p-Chlorphenylesssigsäurechlorid    um  setzt.

   Die neue     Verbindung,    die 3'-(4"-Chlor       phenylacetylamino)-benzoyl-3,4-dichloranilin-          6-sudfons@äure,    ist eine spröde, bräunliche  Masse, die sich zur Verwendung als     Motten-          s,chutzmittel    eignet.  



  <I>Beispiel:</I>  18     Teile        3'-Aminobenzoyl-3.,4-,diohlorani-          lin-6-sulfonsäure    werden in 100     Volumteilen     trockenem     Pyridin    gelöst und unter Rühren  und Kühlen mit Eiswasser mit 10 Teilen       p-Chlorphenyless-igsäurechlorid    in kleinen  Portionen versetzt. Nachher wird 5 Stunden  bei gewöhnlicher Temperatur gerührt, dann    noch 1     Stunde    auf<B>50-60'</B> erwärmt, mit       etwas        8odalösung        versetzt    und dampfdestil  liert, bis kein     Pyridin    mehr übergeht.

   Aus  dem     Rückstand    wird die     Acylverbinduug    mit  Salzlösung als Harz abgeschieden, die     wäss-          rige    Lösung abgegossen und das Harz im       Vakuumgetrocknet,    wodurch dieses, als  spröde, bräunliche Masse erhalten wird.



  Process for the preparation of a halogen-substituted acylaminosulfonic acid. The subject of the present Zueatz patent is a process for the production of a halogen-substituted acylaminosulfonic acid, characterized in that 3'-aminobenzoyl-3,4 -diohlorauiliu-6-sulfonic acid is reacted with p-chlorophenylacetic acid chloride.

   The new compound, the 3 '- (4 "-chlorophenylacetylamino) -benzoyl-3,4-dichloroaniline-6-sudfons @ acid, is a brittle, brownish mass which is suitable for use as a moth repellent.



  <I> Example: </I> 18 parts of 3'-aminobenzoyl-3, 4-, diohloraniline-6-sulfonic acid are dissolved in 100 parts by volume of dry pyridine and mixed with 10 parts of p-chlorophenyless- with stirring and cooling with ice water igsäurechlorid added in small portions. The mixture is then stirred for 5 hours at normal temperature, then heated to <B> 50-60 '</B> for a further hour, mixed with some 8oda solution and steam distilled until no more pyridine passes over.

   The acyl compound is separated from the residue with salt solution as resin, the aqueous solution is poured off and the resin is dried in vacuo, whereby it is obtained as a brittle, brownish mass.
