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-Phenylacetyl-a-uudecylbenzylarnin sulfiert.
Die neue Sulfonsäure bildet als Natrium salz ein weisses Pulver, dessen wässrige Lö sungen stark schäumen. Sie kann als Wasch- und Netzmittel und als Kalkseifenemulgator Verwendung finden. <I>Beispiel:</I> 26,1 Teile a-Undecylbenzylanrin (herge stellt nach den Angaben im Hauptpatent) werden durch 6stündiges Kochen unter Rück fluh mit 25 Teilen Phenylessigsäurechlorid in das N-Pheriylacetyl-a-undecyl-N-benzyl- amin übergeführt.
Dann wird das überschüs sige Phenylessigsäurechlorid durch Wasser zersetzt und der Rückstand durch Ausäthern gewonnen. 0,1 Mol N-Phenylacetyl-a-urrdecyl-benzyl- amin werden bei<B>01</B> in 100 Teilen Schwefel säuremonohydrat gelöst und langsam bei dieser Temperatur mit 40 Teilen 26 ;oigem Oleum sulfoniert. Nach 2 Stunden trägt man die Sulfonierungsmasse in 500 Teile Eis ein und neutralisiert bei 0-10 o mit Natronlauge.
Nach dem Eindampfen und Trocknen erhält man ein weisses Pulver, dessen wässrige Lö sungen 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-phenylacetyl-α-uudecylbenzylamine is sulphated.
The new sulfonic acid forms a white powder as sodium salt, the aqueous solutions of which foam strongly. It can be used as a detergent and wetting agent and as a lime soap emulsifier. <I> Example: </I> 26.1 parts of a-undecylbenzylanrin (produced according to the information in the main patent) are converted into the N-Pheriylacetyl-a-undecyl-N-benzyl- by refluh for 6 hours with 25 parts amine transferred.
The excess phenylacetic acid chloride is then decomposed by water and the residue is obtained by etherification. 0.1 mol of N-phenylacetyl-a-urrdecyl-benzyl-amine are dissolved in 100 parts of sulfuric acid monohydrate at 01 and slowly sulfonated at this temperature with 40 parts of 26% 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, the aqueous solutions of which foam strongly.
