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.
