Description
Verfahren zur Herstellung einer höher molekularen a-substituierten Benzylaminsulfonsäure. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung einer höher molekularen a-substituierten Benzylaminsul- fonsäure, dadurch gekennzeichnet, dass man N-Phenoxyacetyl-a-undecylbenzylamin sul- fiert.
Die neue Sulfonsäure bildet als Natrium salz ein weisses, in Wasser leicht lösliches Pulver, dessen wässrige Lösungen stark schäu men. Sie kann als Wasch- und Netzmittel und als $alkseifenemulgator Verwendung fin den.
<I>Beispiel:</I> 0,1 1VIol a-Undecylbenzylamin (hergestellt nach den Angaben im Hauptpatent) werden in 200 Volumteilen absolutem Benzol gelöst mit 0,15 Mol Phenoxyessigsäurechlorid so lange unter Rückfluss gekocht, bis keine Salz säure mehr entweicht.
Dann wird zur Zer störung des überschüssigen Säurechlorids kurz dampfdestilliert, die Benzollösung von der wässrigerr Schicht abgetrennt und das N Phenoxyacetyl-a-undecylbenzylamin durch Eindunsten gewonnen. 0,1 2o1 N-Phenoxyacetyl-a-undecylben- zylamin werden bei 0 in 100 Teilen Schwe- felsäuremonohydrat gelöst und bei dieser Temperatur mit 40 Teilen 26 o/oigem Oleum sulfoniert.
Nach 2 Stunden trägt man die Sulfonierungsmasse in 500 Teile Eis ein und neutralisiert bei 0-10o mit Natronlauge. Nach dem Eindampfen und Trocknen erhält man ein weisses Pulver, dessen klare wässrige Lösungen stark schäumen.
Process for the preparation of a higher molecular weight α-substituted benzylamine sulfonic acid. The present patent relates to a process for the preparation of a higher molecular weight α-substituted benzylamine sulphonic acid, characterized in that N-phenoxyacetyl-α-undecylbenzylamine is sulphated.
As sodium salt, the new sulfonic acid forms a white powder that is easily soluble in water, the aqueous solutions of which are very foamy. It can be used as a detergent and wetting agent and as an alkali soap emulsifier.
<I> Example: </I> 0.1 1VIol a-undecylbenzylamine (prepared according to the information in the main patent) dissolved in 200 parts by volume of absolute benzene with 0.15 mol of phenoxyacetic acid chloride refluxed until no more hydrochloric acid escapes.
Then briefly steam distilled to destroy the excess acid chloride, the benzene solution is separated from the aqueous layer and the N-phenoxyacetyl-a-undecylbenzylamine is obtained by evaporation. 0.1 2o1 N-phenoxyacetyl-a-undecylbenzylamine are dissolved at 0 in 100 parts of sulfuric acid monohydrate and sulfonated at this temperature with 40 parts of 26% strength oleum.
After 2 hours, the sulfonation mass is introduced into 500 parts of ice and neutralized at 0-10 ° with sodium hydroxide solution. After evaporation and drying, a white powder is obtained whose clear aqueous solutions foam strongly.
