Description
Terfahren zur Herstellung eines wertvollen SullIerungsproduktes. Im Hauptpatent Nr. 148482 ist ein Ver fahren zur Herstellung eines wertvollen Sul- fierungsproduktes beschrieben, das insbeson dere darin besteht, dass man Rizinusölsäure- amid bei An- oder Abwesenheit von Lösungs- oder Verdünnungsmitteln mit sulfierend. wir kenden Mitteln behandelt.
Es wurde nun gefunden, doss man in ana loger Weise ebenfalls ein wertvolles Sul- fierungsprodukt erhalten kann, wenn man Ölsäurediäthylamid mit sulflerend wirkenden Mitteln, z. B. Schwefelsäure, Schwefelsäure- monohydrat, Oleum, Chlorsulfonsäure usw., vorteilhaft bei niederen Temperaturen be handelt.
Das erhaltene Produkt zeichnet sich durch ein besonders hohes Netzvermögen aus. <I>Beispiel:</I> <B>100</B> Gewichtsteile Olsäurediäthylamid werden in<B>800</B> Gewichtsteilen Trichloräthylen gelöst und mit<B>85</B> (4ewichtsteilen Schwefel- säure,monohydi-at, vorteilhaft bei einer Tem peratur unter<B>0 "</B> C, behandelt. Nach dem Ver- dünnen mit Eiswasser trennt man die untere Schicht ab und neutralisiert sie.
Die hierbei erhaltene, in der Regel klare Lösung, trübt sich bei weiterem Zusatz von Wasser und trennt sich nach einigem Stehen in zwei Schichten, von welchen die untere, das Trichloräthylen und die nicht mit Schwef el- säure in Reaktion getretenen Bestandteile enthaltende, abgezogen wird. Die obere Schicht, die noch etwas Trichloräthylen und Wasser enthält, wird so weit abgedampft, bis das Produkt den gewünschten Gehalt an stilfier- tem Ölsäurediäthylamid aufweist.
Approach to the production of a valuable liquidation product. The main patent no. 148482 describes a process for the production of a valuable sulphonation product, which consists in particular in that castoroleic acid amide is sulphurised in the presence or absence of solvents or diluents. we treated means.
It has now been found that a valuable sulphuration product can also be obtained in an analogous manner if oleic acid diethylamide with sulphurizing agents, eg. B. sulfuric acid, sulfuric acid monohydrate, oleum, chlorosulfonic acid, etc., advantageously be treated at low temperatures.
The product obtained is characterized by a particularly high wetting power. <I> Example: </I> <B> 100 </B> parts by weight of oleic acid diethylamide are dissolved in <B> 800 </B> parts by weight of trichlorethylene and mixed with <B> 85 </B> (4 parts by weight of sulfuric acid, monohydric acid at, advantageously at a temperature below <B> 0 "</B> C. After thinning with ice water, the lower layer is separated off and neutralized.
The usually clear solution obtained in this way becomes cloudy with further addition of water and, after standing for a while, separates into two layers, from which the lower one, containing the trichlorethylene and the constituents that did not react with sulfuric acid, is removed . The upper layer, which still contains some trichlorethylene and water, is evaporated until the product has the desired content of styled oleic acid diethylamide.
