Description

  

  Verfahren zur Herstellung einer höher molekularen     a-substitnierten          Benzylaminsulfonsäure.       Gegenstand des vorliegenden Patentes  ist ein Verfahren zur Herstellung einer höher  molekularen     a-substituierten        Benzylaminsul-          fonsäure,    dadurch gekennzeichnet, dass man       N-Formyl-a-undecylbenzylamin        sulfiert.     



  Die neue     Sulfonsäure    bildet als Natrium  salz ein helles Pulver, das in Wasser sehr  gut löslich ist und dessen     wässrige    Lösungen  stark schäumen. Sie kann als Wasch- und  Netzmittel und als     Kalkseifenemulgator    Ver  wendung finden.  



  <I>Beispiel:</I>  300 Teile     Lauroylbenzol    (hergestellt aus       Palmkernfettsäure,    Fraktion     Kp14        mm    150 bis  220 0 und Benzol werden vermischt mit 210  Teilen     konz.        Ammonformiat    (830 Teile     Amei-          sensäure        85%,

          neutralisiert        mit        1080        Teilen          Ammoniak        25        %        und        Eindampfen        auf        900        bis     950 Teile).

   Innert vier Stunden wird unter  sehr gutem Rühren auf<B>180-1850</B> geheizt,  wobei Wasser     abdestilliert.        Naehdem    man  5-6 Stunden bei dieser Temperatur gehalten  hat, wird die entstandene     Formylverbindung     des     a-Undecyl-benzylamins    durch     Ausäthern       isoliert. Durch Destillieren erhält man ein  fast farbloses Öl vom     Kp"4        mm    = 215-270  .  



  0,1     Mol        Formyl    - a -     undecyl    -     benzylamin     werden bei 0 0 in 100 Teilen Monohydrat  gelöst und langsam bei dieser Temperatur       40        Teile        26        %        iges        Oleum        zugetropft.        Man     rührt drei Stunden bei dieser Temperatur,  trägt die     Sulfonierungamasse    in 500 Teile  Eis ein und neutralisiert bei<B>0-101</B> mit  Natronlauge.

   Nach dem Eindampfen und  Trocknen erhält man ein helles, in Wasser  sehr gut lösliches Pulver, dessen     wässrige     Lösungen stark schäumen.



  Process for the production 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-formyl-α-undecylbenzylamine is sulphated.



  As sodium salt, the new sulfonic acid forms a light powder that is very soluble in water and whose aqueous solutions foam strongly. It can be used as a detergent and wetting agent and as a lime soap emulsifier.



  <I> Example: </I> 300 parts of lauroylbenzene (made from palm kernel fatty acid, fraction Kp14 mm 150 to 220 0 and benzene are mixed with 210 parts of concentrated ammonium formate (830 parts of formic acid 85%,

          neutralized with 1080 parts of ammonia 25% and evaporation to 900 to 950 parts).

   The mixture is heated to <B> 180-1850 </B> over a period of four hours with very good stirring, with water being distilled off. After keeping this temperature for 5-6 hours, the resulting formyl compound of a-undecyl-benzylamine is isolated by etherification. Distillation gives an almost colorless oil with a bp "4 mm = 215-270.



  0.1 mol of formyl - a - undecyl - benzylamine are dissolved in 100 parts of monohydrate at 0 ° and 40 parts of 26% strength oleum are slowly added dropwise at this temperature. The mixture is stirred for three hours at this temperature, the sulfonation mass is introduced into 500 parts of ice and neutralized at 0-101 with sodium hydroxide solution.

   After evaporation and drying, a light-colored powder is obtained which is very soluble in water and whose aqueous solutions foam strongly.
