Description

  

  Verfahren zur Herstellung eines neuen     Tegtilhilfsstoffes.       Es wurde gefunden,     da,ss    man einen neuen       Textilhilfsstoff    erhält, wenn man das     y-n-          Heptadecylbenzimida.zol    mit Anisaldehyd       kondensiert    und auf das entstandene Kon  densationsprodukt ein     Sulfonierungsmittel     einwirken lässt.  



  Das neue Produkt stellt als     Natriumsalz     ein hellgefärbtes Pulver dar, das sich in  Wasser leicht auflöst und dessen wässerige  Lösungen     ausgezeichnete    Nasch-,     Dispergier-          und        Schutzkolloideigenschaften        besitzen.     



  <I>Beispiel:</I>  Man erhitzt     unter        C02-Atmosphäre    und  Rühren das Gemisch von<B>356</B> Teilen     ,u-n-          Heptadeeylbenzimida.zol,    204 Teilen Anis  aldehyd und 4 Teilen Borsäure auf 200 bis  210'. Eine Viertelstunde     nachdem,die    Reak  tionstemperatur erreicht worden ist, fügt man  innerhalb     3/.4    Stunden noch 16 Teile Borsäure  in kleinen Portionen hinzu.

   Das     entstehende          Wasser    lässt man durch Verwendung eines  mit Wasserdampf heiss gehaltenen Kühlers,    und indem man einen     schwachen        C02-,Strom     durch die Apparatur ,gehen lässt, abdampfen.  Nach     21stündigem    Erhitzen auf 200     bis    210'       ist    die     Reaktion    beendet. Man bläst gegebe  nenfalls hierauf den     überschüssigen    Anisalde  hyd mit Wasserdampf ab, trennt     das    Reak  tionsprodukt vom Wasser und trocknet das  selbe im Vakuum auf dem Wasserbade.

   Das  bei<B>100'</B>     flüssige    Produkt     erstarrt    nach  einiger Zeit bei     Zimmertemperatur        zu,    einer  weichen viskosen Masse.  



  In einem mit Rührwerk     versehenen        Rühr-          gefäss    lässt man zu 1100 Teilen     Schwefelsäure-          monohydrat,    das auf einer Temperatur von  etwa<B>15'</B> gehalten     wird,        langsam    50 Teile  geschmolzenes     Anisal        -,cc    - n     -,heptadecylbenz-          imidazol    zufliessen, indem man durch äussere  Kühlung     gleichzeitig    dafür sorgt,     dass    die  Temperatur des     -Gemisches    nicht über 20'  steigt.

   Nachdem alles eingetragen ist und  sich     alles    homogen in der     Schwefelsäure    ge  löst hat, lässt man nun allmählich 90     bis    100  Teile     anhydridhaltigeSchwefelsäure    (24%           S03-Gehalt)    zufliessen, indem die     Sulfonie-          rungstemperatur    auf 12     bis    15   gehalten  wird.  



  Die     Sulfonierung        ist    beendet, wenn eine  Probe der     Reaktionsmasse    sich     in        Wasser     klar auflöst. Die     Sulfonierungsmasse        wird     auf 600 Teile     Eis    gegossen, wobei sich die       Sulfosäure    abscheidet, und von der wässe  rigen     Schwefelsäure    abgetrennt werden kann.

    Nach dem     Neutralisieren    der     Sulfo-säure    mit  verdünnter     Natriumhydroxydlösung    und     Ein-          dampfen    erhält man das     Natriumsalz    der       Sulfonsäure.  



  Process for the production of a new Tegtil auxiliary. It has been found that a new textile auxiliary is obtained if the y-n-heptadecylbenzimida.zol is condensed with anisaldehyde and a sulfonating agent is allowed to act on the resulting condensation product.



  As a sodium salt, the new product is a light-colored powder that dissolves easily in water and its aqueous solutions have excellent snacking, dispersing and protective colloid properties.



  <I> Example: </I> The mixture of <B> 356 </B> parts of u-n-heptadeeylbenzimida.zol, 204 parts of anisaldehyde and 4 parts of boric acid is heated to 200 to 210 'under a CO 2 atmosphere and stirring. A quarter of an hour after the reaction temperature has been reached, 16 parts of boric acid are added in small portions within 3/4 hours.

   The water formed is allowed to evaporate using a condenser kept hot with steam and by allowing a weak stream of CO 2 to flow through the apparatus. After heating to 200 to 210 ° for 21 hours, the reaction has ended. If necessary, the excess anisaldehyde is then blown off with steam, the reaction product is separated from the water and the same is dried in vacuo on the water bath.

   The product, which is liquid at <B> 100 '</B>, solidifies after a while at room temperature to form a soft, viscous mass.



  In a stirring vessel equipped with a stirrer, 50 parts of molten anisal -, cc - n -, heptadecylbenzimidazole are slowly added to 1100 parts of sulfuric acid monohydrate, which is kept at a temperature of about 15 ' inflow by simultaneously ensuring that the temperature of the mixture does not rise above 20 'by external cooling.

   After everything has been added and everything has dissolved homogeneously in the sulfuric acid, 90 to 100 parts of anhydride-containing sulfuric acid (24% SO3 content) are gradually added by keeping the sulfonation temperature at 12 to 15.



  The sulfonation is complete when a sample of the reaction mass dissolves clearly in water. The sulfonation mass is poured onto 600 parts of ice, whereupon the sulfonic acid separates out and can be separated off from the aqueous sulfuric acid.

    After neutralizing the sulfonic acid with dilute sodium hydroxide solution and evaporation, the sodium salt of the sulfonic acid is obtained.
