  Verfahren zur Herstellung eines neuen   Benetzungs-,      Reinigungs-, Emulgierungs-    und Dispergierungsmittels.
Wir haben gefunden, dass   Stearyl #-amino-      äthyltolyläther    der Formel
EMI1.1     
 durch Behandeln mit einem Sulfonierungsmittel in ein wertvolles Benetzungs-, Reinigungs-,   Emulgierungs-und      Dispergierungs-    mittel umgewandelt wird.



   Beispiel :
15, 1 Teile ¯-AminoÏthyltolylÏther, der aus Orthocresol erhalten werden kann, indem man zunächst   Tolyloxyäthylchlorid    nach einem der   Herstellungs@eise des ¯-Phenoxy-    äthylchlorids genau analogen Verfahren   (Jour-    nal American Chemical Society 1926, 48, 2745) herstellt und es durch Einwirkung von Ammoniak auf bekannte Weise in den   s-Amino-    äthyltolyläther, ein farbloses   Öl,    überführt, werden mit 28, 5 Teilen Stearinsäure auf   170-180"0    erhitzt, bis zum Aufhören der Entwicklung von Wasser.

   Der so erhaltene rohe   Stearylaminoäthyltolyläther ist    ein hellbrauner, wachsähnlicher Festkörper, der bei ungefähr   60   C schmilzt.    Er wird   sulfoniert,    indem man ihn in sein   anderthalbfaches    Gewicht   Schwefelsäure-Monohydrat    von 20 bis 25¯ C einr hrt.



   Wenn eine Probe mit Wasser eine klare, schäumende Lösung gibt, wird das Sulfone  rungsgemisch    in so viel Natronlauge   gegoseen,    dass man ein neutrales Gemenge erhält. Die erhaltene Creme oder Paste ist gebrauchsfertig zur Verwendung als Reinigungs-oder   Dispergierungsmittel.    Sie kann indessen durch Trocknen in einen weissen, körnigen   Festkör-    per umgewandelt werden, der sich leicht zu einem feinen weissen Pulver vermahlen lässt.



  Das neue Produkt ist ein wei¯er Festkörper, der sich leicht in Wasser zu schäumenden Lösungen   lost,    welche in Gegenwart von   Chlorkalzium    und Mineralsäuren beständig sind. Sie sind besonders brauchbar zum Rei nigen von Wolle oder zum Dispergieren von   Ealkseifen    bei dieser und andern Wasohund Reinigungsoperationen.



  



  Process for the production of a new wetting, cleaning, emulsifying and dispersing agent.
We have found that stearyl # -amino-ethyltolyl ether of the formula
EMI1.1
 is converted into a valuable wetting, cleaning, emulsifying and dispersing agent by treatment with a sulfonating agent.



   Example:
15.1 part ¯-AminoÏthyltolylÏther, which can be obtained from Orthocresol by first tolyloxyethyl chloride by one of the manufacturing methods of ¯-Phenoxyethylchlorids exactly analogous (Journal American Chemical Society 1926, 48, 2745) and it by the action of ammonia in the known manner in the s-amino-ethyltolylether, a colorless oil, are heated with 28.5 parts of stearic acid to 170-180 "0 until the development of water ceases.

   The crude stearylaminoethyl tolyl ether obtained in this way is a light brown, wax-like solid that melts at about 60.degree. It is sulfonated by stirring it into its one and a half times its weight of sulfuric acid monohydrate at temperatures between 20 and 25 ºC.



   If a sample with water gives a clear, foaming solution, the mixture of sulfones is poured into so much sodium hydroxide solution that a neutral mixture is obtained. The cream or paste obtained is ready for use as a cleaning or dispersing agent. However, it can be converted into a white, granular solid by drying, which can easily be ground to a fine white powder.



  The new product is a white solid that easily dissolves in water to form foaming solutions, which are stable in the presence of calcium chloride and mineral acids. They are particularly useful for cleaning wool or for dispersing earth soaps in this and other waso and cleaning operations.
