Description
Verfahren zur Herstellung einer höher molekularen a-substituierten Benzylamiusulfonsäur e. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung einer höher molekularen, a-substituierten Benzylaminsul- fonsäure, dadurch gekennzeichnet, dass man N - Acetyl - N - methyl - a - undecylbenzylamin sulfiert.
Die neue Sulfonsäure bildet als Natrium salz ein helles, in Wasser spielend leicht lös liches Pulver, dessen wässrige Lösungen ziemliches Schaumvermögen zeigen. Sie kann als Wasch- und Netzmittel und als Kalk seifenemulgator Verwendung finden.
<I>Beispiel:</I> 0,1 Hol des nach den Angaben im Zu satzpatent Nr. 211795 erhaltenen N-Methyl- a-undecylbenzylamins wird mit 0,2 Hol Essigsäurechlorid 6 Stunden unter Rückfluss gekocht, dann mit Wasser versetzt, ausge- äthert und die Ätherlösung mit verdünnter Sodalösung gewaschen. Der Äther wird ab destilliert.
Das zurückbleibende Acetyl-N- methyl-a-undecylbenzylamin bildet ein Uel- les 01. 0,1 Hol desselben werden bei 0 in 100 Teilen Monohydrat gelöst und langsam bei dieser Temperatur mit 40 Teilen 26 % igem Oleum sulfiert. Nach 2 Stunden trägt man die Sulfierungsmasse in 500 Teile Eis ein und neutralisiert bei 0 bis<B>10'</B> mit Natron lauge. Nach dem Eindampfen und Trocknen erhält man ein helles, in Wasser spielend leicht lösliches Pulver.
Die Lösung zeigt ziemliches Schaumvermögen.
Process for the preparation of a higher molecular weight α-substituted Benzylamiusulfonsäur e. The subject of the present patent is a process for the preparation of a higher molecular weight, α-substituted benzylamine sulphonic acid, characterized in that N - acetyl - N - methyl - a - undecylbenzylamine is sulphated.
As a sodium salt, the new sulfonic acid forms a pale powder that is easily soluble in water and whose aqueous solutions show considerable foaming power. It can be used as a detergent and wetting agent and as a lime soap emulsifier.
<I> Example: </I> 0.1 hol of the N-methyl-a-undecylbenzylamine obtained according to the information in additional patent no. 211795 is refluxed with 0.2 hol acetic acid chloride for 6 hours, then mixed with water, extracted - ether and the ether solution washed with dilute soda solution. The ether is distilled off.
The remaining acetyl-N-methyl-a-undecylbenzylamine forms a Uels 01. 0.1 Hol of the same are dissolved at 0 in 100 parts of monohydrate and slowly sulfated at this temperature with 40 parts of 26% oleum. After 2 hours, the sulphonation mass is introduced into 500 parts of ice and neutralized at 0 to 10 'with sodium hydroxide solution. After evaporation and drying, a light-colored powder that is easily soluble in water is obtained.
The solution shows quite a foaming power.
