Description

  

  Verfahren zur Herstellung einer höher molekularen     a-substituierten          Benzylaminsulfonsäur    e.    Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer höher  molekularen     a-substituierten        Benzylaminsul-          fonsäure,    dadurch gekennzeichnet, dass man       N-Acetyl-a-uiidecylbenzylamin        sulfiert.     



  Die neue     Sulfonsäure    bildet als Natrium  salz ein helles Pulver, dessen     wässrige    Lösun  gen stark schäumen. Sie kann als     Wasch-          und    Netzmittel und als     Kalkseifenemulgator     Verwendung finden.    <I>Beispiel:</I>  26,1 Teile     a-Undecyl-benzylamin    (herge  stellt nach den Angaben im Hauptpatent)  werden zusammen mit 20 Teilen     Acetylchlo-          rid    5 Stunden unter     Rückfluss    gekocht, dann  mit Wasser versetzt,     ausgeäthert    und die  Ätherlösung mit verdünnter     Sodalösung    ge  waschen.

   Nach dem Verjagen des Äthers hin  terbleibt ein farbloses Öl, das allmählich er  starrt.    0,1     lylol        Acetyl-a-undecyl-N-benzylamin     werden bei<B>00</B> in 100 Teilen Schwefelsäure  inonohydrat gelöst und langsam 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     Natronlange.     Nach dem Eindampfen und Trocknen erhält  man ein helles Pulver, dessen klare     wässrige     Lösungen stark schäumen.



  Process for the preparation of a higher molecular weight α-substituted benzylamine sulfonic acid e. The present patent relates to a process for the preparation of a higher molecular weight α-substituted benzylamine sulphonic acid, characterized in that N-acetyl-α-uiidecylbenzylamine is sulphated.



  As sodium salt, the new sulfonic acid forms a pale powder, 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-undecylbenzylamine (produced according to the information in the main patent) are refluxed for 5 hours together with 20 parts of acetyl chloride, then water is added, and the ether solution is extracted Wash with diluted soda solution.

   After the ether has been chased away, a colorless oil remains, which gradually it stares. 0.1 lylene of acetyl-a-undecyl-N-benzylamine is dissolved in 100 parts of sulfuric acid inonohydrate at 00 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 soda. After evaporation and drying, a pale powder is obtained, the clear aqueous solutions of which foam strongly.
