Verfahren zur Darstellung einer Dimethylphenylbenzylammoniumdisulfosäure.
Es wurde gefunden, dass bei dem Verfahren des Stammpatentes das Dimethylsulfat oder das Halogenmethyl durch die Methylester von Sulfosäuren ersetzt werden kann.
Um zu verhüten, dass bei der Reaktion des Sulfosäureesters mit der wässrigen Lösung der Methylbenzylanilindisulfosäure infolge Verseifung geringer Mengen des Sulfosäureesters saure Reaktion eintritt, ist es zweckmässig, eine gewisse Menge Kalziumkarbonat oder eines ähnlich wirkenden Mittels zuzusetzen.
Bei s pie I : 430 Teile einer Lösung von Methylbenzlanilindisulfosäure (Kalziumsalz), enthaltend 180 Teile Methylbenzylanilindisulfosäure, werden mit 95 Teilen p-Toluolsulfe- säuremethylester und 10 Teilen Schlemm kreide unter gutem Rühren solange auf etwa 60 C erwärmt, bis der Sulfosäureester verschwunden ist. Die so erhaltene Lösung kann entweder unmittelbar oder nach dem Abscheiden des Salzes der Toluolsulfosäure zur Trockne verdampft werden. Das erhaltene Kalksalz der Dimethylphenylbenzylammonium- disulfonsäure ist ein gelblicher, in Wasser sehr leicht löslicher Körper.
In diesem Beispiel kann der p-Tolnolsulfosäuremethylester durch dite methylester anderer Sulfosäuren ersetzt werden.

Process for the preparation of a dimethylphenylbenzylammonium disulfonic acid.
It has been found that in the process of the parent patent the dimethyl sulfate or halomethyl can be replaced by the methyl esters of sulfonic acids.
In order to prevent acidic reactions occurring during the reaction of the sulfonic acid ester with the aqueous solution of methylbenzylanilinedisulfonic acid as a result of saponification of small amounts of the sulfonic acid ester, it is advisable to add a certain amount of calcium carbonate or a similar agent.
At pie I: 430 parts of a solution of methylbenzlaniline disulfonic acid (calcium salt) containing 180 parts of methylbenzylaniline disulfonic acid, 95 parts of methyl p-toluenesulfate and 10 parts of Schlemm's chalk are heated to about 60 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. The calcium salt of dimethylphenylbenzylammonium disulphonic acid obtained is a yellowish body which is very easily soluble in water.
In this example, the methyl p-tolnol sulfate can be replaced by the methyl ester of other sulfonic acids.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
