  Verfahren zur Darstellung einer   Dimethylbenzylphenylammoniummonosulfosäure.   



   Es wurde gefunden, dass in dem Verfahren des Stammpatentes die Methylbenzylanilindisulfosäure durch die   Methylbenzylanilinmonosulfosäure   ersetzt werden kann, welche die Sulfogruppe im Benzylrest enthält. Die so erhaltene   Dimethylbenzylphenylainnionium-   monosulfosäure ist wie die   Disulfosäure   eine für Druckereizwecke sehr wertvolle Verbindung. 



  Sie ist in Wasser sehr leicht löslich. Beim Erwärmen dieser Lösung   mit Athylanilin   entsteht die bekannte Äthylbenzylanilinsulfosäure und Dimethylanilin. 



   Der Verbindung dürfte folgende Formel zukommen : 
 EMI1.1 
   Beispiel : 400 Teile   einer Lösung von Methylbenzylanilinmonosulfosäure (Kalziumsalz), enthaltend 140 Teile Methylbenzylanilinsulfosäure, werden mit 95 Teilen p-Toluolsulfosäuremethylester und 10 Teilen Schlemmkreide unter gutem Umrühren solange auf 600 C erwärmt, bis der   Sulfonsäureester   verschwunden ist. Die so erhaltene Lösung kann entweder unmittelbar oder nach dem Abscheiden des Salzes der   Toluolsulfosäure   zur Trockne verdampft werden.

  Process for the preparation of a dimethylbenzylphenylammonium monosulfonic acid.



   It has been found that in the process of the parent patent the methylbenzylaniline disulfonic acid can be replaced by the methylbenzylaniline monosulfonic acid, which contains the sulfo group in the benzyl radical. The dimethylbenzylphenylainnionium monosulfonic acid obtained in this way, like the disulfonic acid, is a very valuable compound for printing purposes.



  It is very easily soluble in water. When this solution is heated with ethylaniline, the well-known ethylbenzylaniline sulfonic acid and dimethylaniline are produced.



   The compound should have the following formula:
 EMI1.1
   Example: 400 parts of a solution of methylbenzylaniline monosulfonic acid (calcium salt) containing 140 parts of methylbenzylaniline sulfonic acid, 95 parts of methyl p-toluenesulfate and 10 parts of chalk are heated to 600 C with thorough stirring until the sulfonic acid ester has disappeared. The solution obtained in this way can be evaporated to dryness either immediately or after the salt of toluenesulfonic acid has separated out.
