Description

  

  Verfahren zur Herstellung einer höher molekularen     u-substitnierten          Benzylaminsulfonsäure.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer höher  molekularen,     a-substituierten        Benzylaminsul-          f        onsäure,    dadurch gekennzeichnet, dass man       N-Benzoyl    - N -     methyl    - a -     undecylbenzylamin          sulfiert.     



  Die     neue        Sulfonsäure    bildet als Natrium  salz ein helles, in Wasser leicht lösliches Pul  ver. Sie kann als Wasch- und Netzmittel  und als     Kalkseifenemulgator    Verwendung       finden.     



  <I>Beispiel:</I>  27,5 Teile des nach den     Angaben    im Zu  satzpatent Nr. 211795 erhaltenen     N-Methyl-          a-undecylbenzylamins    werden mit 25 Teilen       Benzoylchlorid    auf 130 bis 140' erhitzt.

    Nach 24     Stunden    wird die Masse mit heissem  Wasser     emulgiert,    kurz mit Dampf destil  liert und der Rückstand     ausgeäthert.    Die  Ätherlösung wird durch Ausziehen mit ver  dünnter     Sodalösung    von der     Benzoesäure    be  freit und der Äther     abdestilliert.    0,

  1     Mol    des    erhaltenen     N-Benzoyl-N    -     methyl    - a -     undecyl-          benzylamins    werden bei 0   in 100 Teilen  Monohydrat gelöst und langsam bei dieser     2s     Temperatur mit 40 Teilen 26%igem     Oleum     sulfoniert. Nach 2 Stunden trägt man die       Sulfonierungsmasse    in 500 Teile Eis ein und  neutralisiert bei 0 bis 10   mit Natronlauge.  Nach dem Eindampfen und Trocknen erhält so  man     ein    helles, in Wasser leicht lösliches  Pulver.



  Process for the production of a higher molecular weight u-substituted benzylamine sulfonic acid. The subject matter of the present patent is a process for the preparation of a higher molecular weight, α-substituted benzylamine sulphonic acid, characterized in that N-benzoyl - N - methyl - a - undecylbenzylamine is sulphated.



  As sodium salt, the new sulfonic acid forms a light-colored powder that is easily soluble in water. It can be used as a detergent and wetting agent and as a lime soap emulsifier.



  <I> Example: </I> 27.5 parts of the N-methyl-a-undecylbenzylamine obtained according to the information in additional patent no. 211795 are heated to 130 to 140 ° with 25 parts of benzoyl chloride.

    After 24 hours the mass is emulsified with hot water, briefly distilled with steam and the residue is extracted with ether. The ether solution is freed from the benzoic acid by drawing it out with dilute soda solution and the ether is distilled off. 0,

  1 mol of the N-benzoyl-N-methyl-a-undecylbenzylamine obtained is dissolved in 100 parts of monohydrate at 0 and slowly sulfonated at this temperature for 2 seconds 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 light-colored powder which is easily soluble in water is obtained.
