Description
Verfahren zur Herstellung eines neuen Benetzungs-, Reinigungs-, Emulgierungs- und Dispergierungsmittels. Wir haben gefunden, dass der Stearyl-p- Amitioäthyltolyäther (Formel C171136 - CO- NH-CH2-CH20 C6H4CHs, zu dessen Herstel lung ein technisches m- und p-gresolgemisch verwendet wurde,
durch Behandeln mit einem Sulfonierungsmittel in ein wertvolles Benet- zungs-, Reinigungs-, Emulgierungs- und Dis- pergierungsmittel umgewandelt wird.
<I>Beispiel:</I> 15,1 Teile P-Aminoäthyltolyläther, der aus einem technischen Meta- und Paracresolge- misch erhalten werden kann, indem man zu nächst Tolylogyäthylchlorid nach einem der Herstellungsweise des ss-Pbenoxyäthylchlorids genau analogen Verfahren (Jour. Amr. Chem. Soc. 1926, 48, 2745) herstellt und es durch Einwirkung von Ammoniak auf bekannte Weise in den ss-Aminoäthyltolyläther über führt, ein farbloses Öl, werden mit 28,
5 Tei len Stearinsäure auf 170-180<B>0</B> C erhitzt, bis zum Aufhören der Entwicklung von Was ser. Der so erhaltene rohe Stearylaminoäthyl- tolyläther ist ein hellbrauner, wachsähnlicher Festkörper, der bei ungefähr 60 C schmilzt. Er wird sulfoniert, indem man ihn in sein an derthalbfaches Gewicht Schwefelsäure-Mono- hydrat von 20-251) C einrührt: Wenn eine Probe mit Wasser eine klare schäumende Lösung gibt, wird das Sulfonie- rungsgemisch in so viel Natronlauge gegossen, dass man ein neutrales Gemenge erhält.
Die erhaltene Cri;me oder Paste ist gebrauchs fertig zur Verwendung als Reinigungs- oder Dispergierungsmittel. Sie kann indessen durch Trocknen in einen weissen, körnigen Fest körper umgewandelt werden, der sich leicht zu einem feinen weissen Pulver vermahlen lässt.
Das neue Produkt ist ein weisser Fest körper, der sich leicht in Wasser zu schäu menden Lösungen löst, welche in Gegenwart von Chlorkalzium und Mineralsäuren bestän- dig sind. Sie sind besonders brauchbar zum Reinigen von Wolle oder zum Dispergieren von Kalkseifen bei dieser und andern Wasch- und Reinigungsoperationen.
Process for the production of a new wetting, cleaning, emulsifying and dispersing agent. We have found that the stearyl-p-Amitioäthyltolyäther (formula C171136 - CO-NH-CH2-CH20 C6H4CHs, for the production of a technical m- and p-gresol mixture was used,
is converted into a valuable wetting, cleaning, emulsifying and dispersing agent by treatment with a sulfonating agent.
<I> Example: </I> 15.1 parts of P-aminoethyltolyl ether, which can be obtained from a technical meta- and paracresol mixture by first adding tolylogyethyl chloride using a method exactly analogous to the method of preparation of β-pbenoxyethyl chloride (Jour. Amr. Chem. Soc. 1926, 48, 2745) and converts it into the β-aminoethyltolyl ether in a known manner by the action of ammonia, a colorless oil, are mixed with 28,
5 parts of stearic acid heated to 170-180 <B> 0 </B> C until the development of water stops. The crude stearylaminoethyl tolyl ether obtained in this way is a light brown, wax-like solid that melts at around 60.degree. It is sulphonated by stirring it into its one-half weight sulfuric acid monohydrate at 20-251) C: If a sample with water gives a clear, foaming solution, the sulphonation mixture is poured into enough sodium hydroxide solution that one can receives a neutral mixture.
The cream or paste obtained is ready to use as a cleaning or dispersing agent. However, it can be converted into a white, granular solid by drying, which can easily be ground into a fine white powder.
The new product is a white solid that dissolves easily in water-foaming solutions that are stable in the presence of calcium chloride and mineral acids. They are particularly useful for cleaning wool or for dispersing lime soaps in this and other washing and cleaning operations.
