Description

         

      Verfahren    zur Herstellung eines neuen     Textilhilfsstoffes.       Es wurde gefunden, dass man ein     ka-          pillaraktives        Kondensationsprodukt    erhält,  wenn man ausgehend vom     1-Chlor-4-nitro-          henzol-2-sulfonsäure-N-oxyä-thylamid    einer  seits die Nitrogruppe durch ein Reduktions  mittel in eine     Aminogruppe    und letztere  hierauf durch ein     Oleylierungsmittel    in eine       Oleylaminogruppe,

      anderseits die     Oxyäthyl-          amidgruppe    mittels Schwefelsäure in den       Schwefelsäureester    dieser Gruppe überführt.  Das so erhaltene Produkt bildet in trockenem  Zustande ein helles Pulver, das sich in war  mem Wasser unter Bildung einer stark  schäumenden Lösung, die eine ausgezeich  nete Netz- und Waschwirkung besitzt, auf  löst.  



  <I>Beispiel:</I>  Durch Eintragen von 256 Teilen     1-Chlor-          4-nitrobenzol-2-sulfonsäurechlorid    in eine  wässerige Lösung von 122 Teilen Äthanol  amin stellt man in üblicher Weise das     1-          Chlor-4-nitrobenzol-2-sulfonsäureoxäthvlamid     her. 281 Teile dieses Körpers werden bei    10 bis 20   in 1100 Teile 100 %     ige    Schwefel  säure eingetragen.

   Die erhaltene Lösung  giesst man in zirka '3000 Teile konzentrierte       Chlornatriumlösung,    wobei nach einigem  Rühren in der Kälte das     Natriumsalz    des       Sehwefelsäureesters    des     1-Chlor-4-nitroben-          zol    - 2. -     sulfonsäureoxyäthylamids    ausfällt.

    Durch Reduktion     mit    Eisen     in    wässeriger  Lösung nach üblichen Methoden erhält man  die entsprechende     4-Aminoverbindung.    In  eine Lösung von 440 Teilen des so gewon  nenen     Aminokörpers    und 82, Teilen Natrium  acetat in 800 Teilen Wasser lässt man bei 5  bis 15   300 Teile     Olsäurechlorid        eintropfen.     Hierauf wird mit     Natriumhydroxyd    neutral  gestellt und 2 bis 3 Stunden bei Zimmertem  peratur nachgerührt. Das erhaltene Produkt  kann in bekannter Weise auf Pasten oder  Trockenpulver verarbeitet werden.



      Process for the production of a new textile auxiliary. It has been found that a capillary-active condensation product is obtained if, starting from 1-chloro-4-nitrohenenzene-2-sulfonic acid-N-oxyethylamide, on the one hand, the nitro group is converted into an amino group by means of a reducing agent and the latter is then converted by an oleylating agent into an oleylamino group,

      on the other hand, the oxyethyl amide group is converted into the sulfuric acid ester of this group by means of sulfuric acid. The product thus obtained forms a pale powder when dry, which dissolves in warm water to form a strongly foaming solution which has excellent wetting and washing properties.



  <I> Example: </I> By introducing 256 parts of 1-chloro-4-nitrobenzene-2-sulfonic acid chloride into an aqueous solution of 122 parts of ethanolamine, the 1- chloro-4-nitrobenzene-2- sulfonic acid oxyethylene amide. 281 parts of this body are entered at 10 to 20 in 1100 parts of 100% sulfuric acid.

   The resulting solution is poured into about 3000 parts of concentrated sodium chloride solution, and after some stirring in the cold, the sodium salt of the sulfuric acid ester of 1-chloro-4-nitrobenzene-2-sulfonic acidoxyethyl amide precipitates.

    The corresponding 4-amino compound is obtained by reduction with iron in aqueous solution by customary methods. In a solution of 440 parts of the amino body won in this way and 82 parts of sodium acetate in 800 parts of water, 5 to 15,300 parts of oleic acid chloride are added dropwise. It is then made neutral with sodium hydroxide and stirred for 2 to 3 hours at room temperature. The product obtained can be processed into pastes or dry powder in a known manner.
