Description

  

  Verfahren zur Herstellung eines neuen     Tegtilhilfsstoffes.       Es wurde gefunden, dass man ein kapillar  aktives Kondensationsprodukt erhält, wenn  man ausgehend vom     1-Nitrobenzol-3-sulfon-          säure-N-oxyäthylamid    einerseits die     Nitro-          gruppe    durch ein Reduktionsmittel in eine       Aminogrupppe    und letztere hierauf durch ein       Lauroylierungsmittel    in eine     Lauroylamino-          gruppe,

      anderseits die     Oxyäthylamidgruppe          mittelst    Schwefelsäure in den     Schwefelsäure-          ester    dieser Gruppe überführt. Das so er  haltene Produkt bildet in trockenem     Zustande     ein     reinweisses    Pulver, das sich in warmem  Wasser unter Bildung einer stark schäumen  den Lösung, die eine ausgezeichnete     Netz-          und    Waschwirkung besitzt, auflöst.  



  <I>Beispiel</I>  Durch Eintragen von 221 Teilen     1-Nitr-o-          benzol-3-sulfonsäurechlorid    in eine wässerige  Lösung von 122 Teilen     Äthanolamin    stellt  man in üblicher Weise das     1-Nitro        3-benzol-          sirlfonsäureoxäthylamid    her. 246 Teile dieses  Körpers werden bei 10-200 in 1000 Teile         1000%ige    Schwefelsäure eingetragen.

   Die er  haltene Lösung giesst man in ca. 3000 Teile  konzentrierte     Ohlornatriumlösung,    wobei nach  einigem Rühren in der Kälte das Natrium  salz des     Schwefelsäureesters    des     1-Nitro-3-          benzolsulfonsäureoxäthylamids    ausfällt.

   Durch  Reduktion mit Eisen in wässeriger Lösung  nach üblichen Methoden erhält man die ent  sprechende     1-Aminoverbindung.    In eine Lö  sung von 380 Teilen des so gewonnenen       Aminokörpers    und 82 Teilen     Natriumacetat     in<B>800</B> Teilen Wasser lässt man bei 5-15 0  218 Teile     Laurylsäurechlorid        eintropfen.    Hier  auf wird     cnit        Natriumhydroxyd    neutral ge  stellt und 2 bis 3 Stunden bei Zimmertempe  ratur nachgerührt. Das erhaltene Produkt  kann in bekannter Weise auf Pasten oder  Trockenpulver verarbeitet werden. .



  Process for the production of a new Tegtil auxiliary. It has been found that a capillary active condensation product is obtained if, starting from 1-nitrobenzene-3-sulfonic acid-N-oxyethylamide, on the one hand the nitro group is converted into an amino group by a reducing agent and the latter is then converted into a lauroylamino group by a lauroylating agent group,

      on the other hand, the oxyethylamide group is converted into the sulfuric acid ester of this group by means of sulfuric acid. The product obtained in this way forms a pure white 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 221 parts of 1-nitr-o-benzene-3-sulfonic acid chloride into an aqueous solution of 122 parts of ethanolamine, 1-nitro-3-benzene-sulfonic acid oxethylamide is prepared in the usual way. 246 parts of this body are entered at 10-200 in 1000 parts of 1000% sulfuric acid.

   The solution he obtained is poured into about 3000 parts of concentrated sodium carbonate solution, and after some stirring in the cold, the sodium salt of the sulfuric acid ester of 1-nitro-3-benzenesulfonic acid oxäthylamide precipitates.

   The corresponding 1-amino compound is obtained by reduction with iron in aqueous solution by customary methods. In a solution of 380 parts of the amino body obtained in this way and 82 parts of sodium acetate in 800 parts of water, 5-15 0 218 parts of lauric acid chloride are added dropwise. Here it is 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. .
