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-Phenogyacetyl-N-methyl-a-undecylbenzyl-          amin        sulfiert.     



  Die neue     Sulfonsäure    bildet als Natrium  salz ein hellbraunes Pulver, dessen     wässrige          Lösungen    schäumen. Sie kann als Wasch  und     Netzmittel        und,    als     Kalkseifenemulgator     Verwendung finden.  



  <I>Beispiel:</I>  55     Teile    des nach den Angaben im Zu  satzpatent Nr. 211795     erhaltenen        N-Methyl-          a-undecylbenzylamins    werden zusammen mit  42 Teilen     Phenogyessigsäurechlorid    5 Stun  den unter     Rückfluss    gekocht, dann mit Was  ser versetzt,     ausgeäthert        und    die Ätherlösung  mit verdünnter     Sodalösung    gewaschen.

       Das     nach dem Verjagen des Äthers hinterblei  bende N-Phenogyacetyl-N-methyl-a-undecyl-         benzylamin    wird in 250 Teilen Schwefel  säuremonohydrat bei Zimmertemperatur ge  löst und unter guter     Kühlung    bei 0   mit  75 Teilen 26%igem     Oleum        sulfiert,    bis eine  Probe in verdünnter Natronlauge klar löslich  ist. Nach der Neutralisation mit Natronlauge  erhält man durch Eindampfen der Lösung  ein hellbraunes Pulver, dessen     wässrige    Lö  sungen schäumen.



  Process for the preparation of a higher molecular weight α-substituted benzylamine sulfonic acid. The subject of the present patent is a process for the preparation of a higher molecular weight, α-substituted benzylamine sulfonic acid, characterized in that N-phenogyacetyl-N-methyl-α-undecylbenzylamine is sulfated.



  The new sulphonic acid forms a light brown powder as sodium salt, the aqueous solutions of which foam. It can be used as a detergent and wetting agent and as a lime soap emulsifier.



  <I> Example: </I> 55 parts of the N-methyl-a-undecylbenzylamine obtained according to the information in additional patent no. 211795 are refluxed for 5 hours together with 42 parts of phenogyacetic acid chloride, then treated with water, extracted with ether and the ether solution washed with dilute soda solution.

       The N-phenogyacetyl-N-methyl-a-undecylbenzylamine remaining after chasing off the ether is dissolved in 250 parts of sulfur acid monohydrate at room temperature and sulfated with good cooling at 0 with 75 parts of 26% oleum until a sample in dilute sodium hydroxide solution is clearly soluble. After neutralization with sodium hydroxide solution, evaporation of the solution gives a light brown powder, the aqueous solutions of which foam.
