Description

  

  Verfahren zur Herstellung eines Textilhilfsmittels.    Wir haben gefunden, dass durch     Sulfo-          nierung    von     Hydroxylgruppen    im     ss,        r-Di-          hydroxy-n-propylamid    von     Cocosnussölsäuren     (wie z. B. nachdem Verfahren gemäss Schweizer  Patent Nr. 175668 erhalten) durch die Wir  kung eines sulfonierenden Agens (wie     Pyridin-          schwefelsäureanhydrid)    ein Textilhilfsmittel  mit wertvollen     Eigenschaften    erhalten wird.

    <I>Beispiel:</I>  Man löst 55 Teile des Produktes aus       j--Diliydroxy-n-pi-opylamin    und     Cocosnussöl-          säuren    in 50 Teilen von trockenem     Pyridin     bei<B>900</B> C auf, setzt 120 Teile fein     gepul-          vertes        Natriumpyrosulfat    von 90     o/oiger    Rein  heit unter eifrigem Umrühren zu und fährt  mit dem Umrühren eine Stunde fort. Nach  dieser Zeit ist das Produkt in Wasser leicht  löslich.

   Alsdann wird das Produkt sorgfältig  in 320 Teile einer 10     o/oigen,    wässerigen Na  triumkarbonatlösung, in welcher es sich zu  einer klaren     Lösung    auflöst, geschüttet, ab  kühlen gelassen, vom kristallisierten Natrium  sulfat     abgefiltert    und das Filtrat durch Ver-    dampfen getrocknet. Auf diese Weise wird  ein weisses Pulver erhalten, welches sich in  Wasser zu einer farblosen, leicht schäumen  den Lösung mit starkem Netzvermögen auflöst.



  Process for the production of a textile auxiliary. We have found that by sulfonating hydroxyl groups in the ss, r-di-hydroxy-n-propylamide of coconut oil acids (as obtained, for example, according to the method according to Swiss patent no Pyridine sulfuric anhydride) a textile auxiliary with valuable properties is obtained.

    <I> Example: </I> One dissolves 55 parts of the product from j-di-hydroxy-n-pi-opylamine and coconut oleic acids in 50 parts of dry pyridine at <B> 900 </B> C, sets 120 Add finely powdered sodium pyrosulfate of 90% purity while stirring vigorously and continue stirring for an hour. After this time the product is easily soluble in water.

   The product is then carefully poured into 320 parts of a 10% aqueous sodium carbonate solution, in which it dissolves to a clear solution, allowed to cool, filtered off from the crystallized sodium sulfate and the filtrate dried by evaporation. In this way a white powder is obtained which dissolves in water to form a colorless, slightly foaming solution with strong wetting properties.

Claims (1)

PATENTANSPRUCH: Verfahren zur Herstellung eines Textil hilfsmittels, dadurch gekennzeichnet, dass man das (3, r-Dihydroxy-n-propylamid von Cocos- nussölsäuren mit einem sulfonierenden Agens behandelt. Der so erhaltene Schwefelsäureester ist in Form seines Natriumsalzes ein weisses Pulver, das sich in Wasser zu einer farblosen, leicht schäumenden Lösung mit starkem Netzver mögen auflöst. PATENT CLAIM: Process for the production of a textile auxiliary, characterized in that the (3, r-dihydroxy-n-propylamide of coconut oil acids is treated with a sulfonating agent. The sulfuric acid ester obtained in this way is a white powder in the form of its sodium salt, dissolves in water to a colorless, slightly foaming solution with strong wetting power. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch ge kennzeichnet, dassman als sulfonierendes Agens Pyridinschwefelsäureanhydrid verwendet. SUBCLAIM: Process according to claim, characterized in that pyridine-sulfuric anhydride is used as the sulfonating agent.
