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.
