Description

  

  Verfahren zur Herstellung einer höher molekularen     a-sulbstituierten          Benzylaminsulfonsäur    e. '    Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer höher  molekularen, a -     substituierten        Benzylamin-          sulfonsäure,    dadurch gekennzeichnet, dass  man     N-Diogypropyl-a-undecyl-(4-methyl-          benzyl)-amin        sulfiert.     



  Die neue     Sulfonsäure    bildet als Natrium  salz ein hellgelbes Pulver, dessen     wässrige     Lösungen ausgeprägte     kapillaraktive    Eigen  schaften besitzen. Sie kann als Wasch- und  Netzmittel und als     galkseifenemulgator     Verwendung finden.  



  <I>Beispiel:</I>  0,1     Mol    a -     Undecyl    - (4 -     methylbenzyl)-          amin    (hergestellt nach den Angaben     im     Zusatzpatent Nr.<B>211796)</B> wird mit 0,15     Mol          Glycerin-a-chlorhydrin    auf     150-160'    er  hitzt, bis keine Salzsäure mehr     entweicht.     Man     äthert    aus,

       wäscht    das überschüssige       Chlorhydrin    mit     Wasser    weg und löst den  nach dem Abdampfen des Lösungsmittels  hinterbleibenden Rückstand in 100 Teilen         Schwefelsäuremonohydrat.    Bei 0   werden  40 Teilte 26     %        iges        Oleum        zugetropft    und ge  rührt, bis sich eine Probe der     Sulfurations-          masse    in Wasser klar löst. Man giesst     auf     500 Teile Eis und     neutralisiert    mit Natron  lauge.

   Nach dem Eindampfen erhält man  ein hellgelbes Pulver; dessen     wässrige    Lösun  gen ausgeprägte     kapillaraktive    Eigenschaf  ten besitzen.



  Process for the preparation of a higher molecular weight α-substituted benzylamine sulfonic acid e. 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-diogypropyl-α-undecyl- (4-methylbenzyl) -amine is sulfated.



  As a sodium salt, the new sulfonic acid forms a pale yellow powder, the aqueous solutions of which have distinctive capillary-active properties. It can be used as a detergent and wetting agent and as a soap emulsifier.



  <I> Example: </I> 0.1 mol of a - undecyl - (4 - methylbenzyl) - amine (prepared according to the information in additional patent no. <B> 211796) </B> is mixed with 0.15 mol of glycerine A-chlorohydrin is heated to 150-160 'until no more hydrochloric acid escapes. One ether out

       washes away the excess chlorohydrin with water and dissolves the residue remaining after evaporation of the solvent in 100 parts of sulfuric acid monohydrate. At 0, 40 parts of 26% oleum are added dropwise and the mixture is stirred until a sample of the sulphurisation mass dissolves in water to give a clear solution. It is poured onto 500 parts of ice and neutralized with sodium hydroxide solution.

   After evaporation, a light yellow powder is obtained; whose aqueous solutions have pronounced capillary-active properties.
