Description
Verfahren zur Herstellung von Dibenzylanilin 4' # -i"-disulfosiiure. Es wurde gefunden, dass rnan die Diben- zylanilin-4' # 4"-disulfosäure in technisch sehr vorteilhafter Weise durch Kondensation von 2 Mol. benzylchlorid-p-sulfosaurern Natrium mit 1 Mol. Anilin in wässeriger Lösung dar stellen kann.
Man erhält eine Lösung, welche, ohne weiteres zur Herstellung von Farbstoffen verwendet werden kann, oder aus welcher die Dibenzylanili -4' # 4"-disulfosäure naeh bekannten Methoden isoliert werden kann. <I>Beispiel:</I> 9,3 kg Anilin werden in 200 Liter Wasser suspendiert und bei<B>701</B> unter Rühren nach einander mit 11 kg Soda und 45 kg benzyl- chlorid-p-sulfosaurerrr Natrium versetzt. Wenn alles eingetragen ist, wird während einer Viertelstunde gekocht, wobei die Umsetzung quantitativ vor sich geht.
Process for the preparation of dibenzylaniline 4 '# 4 "-disulphonic acid. It has been found that dibenzylaniline-4' # 4" -disulphonic acid can be produced in a technically very advantageous manner by condensation of 2 mol of benzyl chloride-p-sulphonic acid with sodium 1 mol. Aniline in aqueous solution can represent.
A solution is obtained which can easily be used for the production of dyes, or from which the dibenzylanili -4 '# 4 "-disulfonic acid can be isolated according to known methods. Example: 9.3 kg Aniline is suspended in 200 liters of water and 11 kg of soda and 45 kg of sodium benzyl chloride-p-sulfosaurrrrrrrrrrrrrrrrrrrrrrr soda added at 701. When everything has been added, boiling for a quarter of an hour the implementation is quantitative.
