Description

  

  Verfahren zur Herstellung eines     Schwefelsäureesters.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines     Schwefel-          säureesters.    Das Verfahren ist dadurch ge  kennzeichnet, dass man     1-Xylyl-2-heptadecyl-          4,6-di-imino-tetrahydro-1,3,5-triazin,    welches  unter Verwendung von rohem     Xylidinge-          misch    hergestellt wurde, mit mindestens der  doppelt molekularen Menge     Glycid    umsetzt  und das     Reaktionsprodukt    in seinen     Schwe-          felsäureester    überführt.  



  Das     Natriumsalz    des neuen Erzeugnisses  ist     ein    wasserlösliches, helles Pulver mit her  vorragenden     kapillaraktiven    Eigenschaften.  Es kann als     Tegtilhilfsprodukt    Verwendung  finden.  



  <I>Beispiel:</I>  Zu 45 Teilen     1-Xylyl-2-heptadecyl-4,6-          di-imino-tetrahydro-1,3,5-triazin,    welches  unter     Verwendung    von rohem     Xylidin-          gemisch    hergestellt wurde, werden in Ge  genwart von 0,2 Teilen     Natriumäthylat    bei  140-150  22 Teile     Glycid        zugetropft.    Die  klare, hellbraune Schmelze wird noch wäh  rend 14 Stunden bei derselben Temperatur       weitergerührt,    bis     eine    homogene     Mischung     entstanden ist.

   Nach dem Abkühlen wird das    Kondensationsprodukt in Form einer braunen  wachsartigen Masse erhalten.  



  15 Teile des so erhaltenen Kondensations  produktes werden in 30     Teilen    Monohydrat so  gelöst und mit 35 Teilen     Oleum    26     %ig    bei  8-10  bis zur Wasserlöslichkeit verrührt.  Die     Sulfurationsmasse    wird     alsdann    auf Eis  gegossen und nach Abtrennen der     wässrigen     Schicht mit     Natronlauge    neutralisiert. Das     a%     Endprodukt bildet ein helles, wasserlösliches  Pulver mit sehr guten     kapillaraktiven    Eigen  schaften. Es besitzt     ein    hervorragendes  Waschvermögen.



  Process for producing a sulfuric acid ester. The subject of the present patent is a process for the production of a sulfuric acid ester. The process is characterized in that 1-xylyl-2-heptadecyl-4,6-di-imino-tetrahydro-1,3,5-triazine, which was prepared using crude xylidine mixture, with at least twice converts a molecular amount of glycide and converts the reaction product into its sulfuric acid ester.



  The sodium salt of the new product is a water-soluble, light powder with excellent capillary-active properties. It can be used as a Tegtil auxiliary product.



  <I> Example: </I> To 45 parts of 1-xylyl-2-heptadecyl-4,6-di-imino-tetrahydro-1,3,5-triazine, which was prepared using a crude xylidine mixture in the presence of 0.2 parts of sodium ethylate at 140-150 22 parts of glycide were added dropwise. The clear, light brown melt is stirred for 14 hours at the same temperature until a homogeneous mixture is formed.

   After cooling, the condensation product is obtained in the form of a brown waxy mass.



  15 parts of the condensation product obtained in this way are dissolved in 30 parts of monohydrate and stirred with 35 parts of 26% oleum at 8-10 to water solubility. The sulphuration mass is then poured onto ice and, after the aqueous layer has been separated off, neutralized with sodium hydroxide solution. The a% end product is a light-colored, water-soluble powder with very good capillary-active properties. It has excellent washing power.
