  Zusatzpatent zum Hauptpatent     Nr.   <B>116156.</B>    Verfahren zur Darstellung eines     alkallechten        grünblauen        Farbstoffes     der     Triphenylmetha.nreihe.       Es wurde gefunden,     dass    man einen     al-          kaliechten    grünblauen Farbstoff der     Triphenyl-          methanreihe    erhält,

   wenn man<B>1</B>     Mol.        o-Sul-          fobenzaldehyd    mit 2     Mol.        p-Ohlorstilfobenzyl-          äthylanilin    kondensiert und das entstandene  Kondensationsprodukt oxydiert.  



  Trocken ist der Farbstoff, der im Zustand  der freien Säure die     Di-p-chlorsulfobenzyldiä-          thyldiaminoti-iphenylkarbinol-o-sLilfosäure    ist,  ein metallisch glänzendes blaues Pulver, das  in Wasser leicht mit schöner blauer Farbe  löslich ist, und färbt Wolle in blaugrünen  Tönen von besonderer Reinheit     undKlarheit,     wobei das Färbebad ausgiebiger als bei  dem entsprechenden chlorfreien Farbstoff er  schöpft wird.-.  



  <I>Beispiel:</I>  Das in bekannter Weise aus     p-Chlorben-          zylehlorid    und     Moiioäthylanilin    erhaltene       p-Chlorbenzyläthylaiiilin    wird     sul:flert,    indem  man<B>1</B> Teil der Base in 1-2 Teilen     Schwefel-          säuremonohydrat    löst und     in    der Kälte so  lange mit zwei Äquivalenten     SO3    in Form    von     Oleum    rührt, bis     Alkalilöslichkeit    einge  treten ist.

   Auf diese Weise tritt eine     Sulfo-          gruppe    in den     Benzylrest    ein. Die neue       Sulfosäure    stellt ein weisses Pulver dar und  ist in Wasser sehr schwer, in Alkalien leicht  löslich.<B>65</B> Teile der     Sulfosäure    werden mit       23        Teilen        o-Sulfobenzaldehyd        (90        %ig)

          in     wässeriger Lösung 24 Stunden unter     Rückfluss     gekocht und die entstandene     Leukosäure    in  saurer Lösung mit     Bleisuperoxyd    zum Farb  stoff oxydiert. Nach dem Abscheiden des  Bleis wird der Farbstoff     ausgesalzen    und  getrocknet.



  Additional patent to main patent no. <B> 116156. </B> Process for the preparation of an alkali-fast green-blue dye of the triphenylmethane series. It has been found that an alkaline green-blue dye of the triphenyl methane series is obtained,

   if <B> 1 </B> mol. o-sulphobenzaldehyde is condensed with 2 mol. p-Ohlorstilfobenzylethylaniline and the condensation product formed is oxidized.



  The dry dyestuff is di-p-chlorosulfobenzyldiä- thyldiaminoti-iphenylkarbinol-o-silfosäure in the state of the free acid, a metallic blue powder which is easily soluble in water with a beautiful blue color, and dyes wool in blue-green tones of particular purity and clarity, whereby the dye bath is exhausted more extensively than with the corresponding chlorine-free dye.



  <I> Example: </I> The p-chlorobenzylethyl aniline obtained in a known manner from p-chlorobenzyl chloride and moiioethyl aniline is sul: flert by adding <B> 1 </B> part of the base in 1-2 parts of sulfur acid monohydrate and stir in the cold with two equivalents of SO3 in the form of oleum until alkali solubility has occurred.

   In this way a sulfo group enters the benzyl radical. The new sulfonic acid is a white powder and is very difficult in water, easily soluble in alkalis. <B> 65 </B> parts of the sulfonic acid are mixed with 23 parts of o-sulfobenzaldehyde (90%)

          Boiled under reflux in aqueous solution for 24 hours and the leuco acid formed is oxidized in acidic solution with lead peroxide to form the dye. After the lead has been deposited, the dye is salted out and dried.
