Description

  

  Verfahren zur Herstellung eines neuen     Textilhilfsmittels.       Wir haben gefunden, dass durch     Sulfonie-          rung    von     Hydroxylgruppen    im     ss,y    -     Dihy-          droxy-n-propylamid    von     Stearinsäure    durch  die Wirkung eines sulfonierenden Agens, wie  zum. Beispiel     Pyridinschwefelsäureanhydrid,     ein neues     Textilhilfsmittel    mit wertvollen  Eigenschaften erhalten wird.  



  <I>Beispiel:</I>       1(17    Teile     Stearinsäure-ss,y-dihydroxy-n-          propylamid    (hergestellt zum Beispiel durch       Zusammenerhitzen    von     Stearinsäure    und     ss,y-          Dihydroxy    - n -     propylamin,    bis kein Dampf  mehr frei wird) werden in 76 Teilen trocke  nem     Pyridin    bei<B>90'</B> C aufgelöst und mit  166 Teilen feingepulvertem, 90%igem Na  triumpyrosulfat behandelt. Das Gemisch  wird eifrig umgerührt und die Temperatur  eine Stunde auf<B>90'</B> C aufrechterhalten.

   Das       igen,     Produkt wird in 400 Teile einer IM gen,  wässerigen     Natriumcarbonatlösung    geschüt-         tet,    in welcher es sich zu einer klaren Lösung  auflöst. Diese wird abgekühlt, vom kristalli  sierten Natriumsulfat     abgefiltert    und bis zur  Trockene verdampft. Auf diese Weise wird  ein weisses Pulver erhalten, welches durch  Auflösen in kochendem Alkohol     (methyl-          alkoholhaltigem    Industriesprit) gereinigt und  vom     zurückbleibenden        Natriumsulfat        abge-          filtert    wird, worauf das Filtrat kristallisie  ren gelassen wird.

   Hierbei wird ein weisser  Festkörper erhalten, welcher in weichem oder  hartem Wasser zu einer reinigenden Lösung  löslich ist.



  Process for the production of a new textile auxiliary. We have found that sulphonation of hydroxyl groups in the ss, y - dihydroxy-n-propylamide of stearic acid by the action of a sulphonating agent such as the. Example pyridine sulfuric anhydride, a new textile auxiliary with valuable properties.



  <I> Example: </I> 1 (17 parts of stearic acid-ss, y-dihydroxy-n-propylamide (produced for example by heating stearic acid and ss, y-dihydroxy - n - propylamine together, until no more steam is released) are dissolved in 76 parts of dry pyridine at <B> 90 '</B> C and treated with 166 parts of finely powdered, 90% sodium pyrosulfate. The mixture is vigorously stirred and the temperature is set to <B> 90' </ Maintain B> C.

   The own product is poured into 400 parts of an IM gene, aqueous sodium carbonate solution, in which it dissolves to a clear solution. This is cooled, filtered off from the crystallized sodium sulfate and evaporated to dryness. In this way a white powder is obtained which is purified by dissolving it in boiling alcohol (industrial fuel containing methyl alcohol) and filtered off from the remaining sodium sulfate, whereupon the filtrate is allowed to crystallize.

   This gives a white solid which is soluble in soft or hard water to form a cleaning solution.
