Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 190717.    Verfahren zur Herstellung eines neuen     Hilfsstoffes.       Es wurde gefunden,     @dass    man einen  neuen Hilfsstoff erhält, wenn man das       N-Äthyl-,u-n-undecylbenzimidazol    mit     sulfie-          rend    wirkenden Mitteln behandelt. Das neue  Produkt bildet in Form seines     Alkalisalzes     eine helle Masse, die sich in Wasser zu einer  klaren, stark schäumenden Lösung, die aus  gezeichnete Wasch-, Netz- und     Dispergier-          e        igenschaften    besitzt, löst.  



  Das     ausgezeichnete    Schaumvermögen des  neuen     Produktes    macht     dasselbe    zum Waschen  lebender Haare besonders wertvoll. Es kann  ferner zur     Herstellung    von Zahnpasten oder  von     Schaumlöschmitteln    verwendet werden.

      <I>Beispiel:</I>    67,2 Teile eines Gemisches, bestehend  hauptsächlich     aus,u-n-Undecylbenzimidazol,     wie     esdurch    Erhitzen von     technischer        Kokos-          fettsäure    mit     o-Phenylendiamin    erhalten  wird, erhitzt man     unter    Druck mit<B>17,3</B> Tei  len     Äthylchlorid    während 17     ,Stunden    auf    150 bis<B>1,55'.</B> Die     Reaktionsmasse    bildet       nach    dem Erkalten eine     salbenartige    Masse,  die in verdünnter Salzsäure klar löslich ist.  



  Man gibt zu 300 Teilen !Schwefelsäure bei  20 bis 25<B>'</B>allmählich<B>100</B> 0 Teile     .des    nachdem  vorigen Absatz erhaltenen     N-Äthylbenz-          imidazolgemisches.    Die     Sulfonierung    voll  zieht sich schon teilweise während des Ein  tragens; sie wird durch     Hinzufliessenlassen     von etwa 50 Teilen 24%igem     Oleum    im  Laufe von zwei bis drei     Stunden    zu Ende  geführt. Sobald .eine Probe sich in verdünn  ten wässerigen Alkalien klar und     vollständig     löst, giesst man das     Sulfonierungsgemisch    auf       Eis,    filtriert und wäscht mit Wasser.

   Die  zurückbleibende     Sulfonsäure    wird in Wasser       verteilt    und mit     Natriumhydrogyd    oder     -kar-          bonat        neutralisiert.  



  <B> Additional patent </B> to main patent no. 190717. Process for the production of a new auxiliary material. It has been found that a new adjuvant is obtained if the N-ethyl-, u-n-undecylbenzimidazole is treated with sulphurizing agents. The new product forms a light-colored mass in the form of its alkali salt, which dissolves in water to form a clear, strongly foaming solution with excellent washing, wetting and dispersing properties.



  The excellent foaming power of the new product makes it particularly valuable for washing living hair. It can also be used to make toothpastes or foam extinguishers.

      <I> Example: </I> 67.2 parts of a mixture consisting mainly of un-undecylbenzimidazole, as is obtained by heating technical coconut fatty acid with o-phenylenediamine, is heated under pressure at 17.3 </B> Partial ethyl chloride for 17 hours to 150 to <B> 1.55 '. </B> After cooling, the reaction mass forms an ointment-like mass that is clearly soluble in dilute hydrochloric acid.



  300 parts of sulfuric acid are gradually added at 20 to 25 parts of 0 parts of the N-ethylbenzimidazole mixture obtained in accordance with the previous paragraph. The sulfonation is already partially carried out during the entry; it is completed by adding about 50 parts of 24% oleum over the course of two to three hours. As soon as a sample dissolves clearly and completely in dilute aqueous alkalis, the sulfonation mixture is poured onto ice, filtered and washed with water.

   The sulfonic acid that remains is distributed in water and neutralized with sodium hydrogen or carbonate.
