Description

  

      Zusatzpatent    zum Hauptpatent Nr.<B>178224.</B>    Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, wenn man     diazotiertes        2-          rlirlirio-5-nitro-plienylmethylsulfori    mit 2. 5       Dimethoxy-I-N-(dimethoxyäthyl)-amirloben-          zol    vereinigt. Der so erhaltene Farbstoff  bildet in trockenem Zustande ein dunkles  Pulver, das sich in organischen Lösungs  mitteln, wie Aceton, Essigester     etc.,    mit  leuchtend blauvioletter Farbe löst.

   Durch  geeignete Zusätze in feine Verteilung ge  bracht, färbt er     Acetatkunstseide    in reinen,  blauvioletten Tönen.  



       Beispiel:     21,6 Teile     2-Arnino-5-nitro-pheriylnlethyl-          sulfon    werden unter kräftigem Rühren in  etwa 300 Teilen Schwefelsäure gelöst und  darauf durch Zusatz von 8 Teilen Natrium  nitrit oder der entsprechenden Menge     Nitro-          syIschwefelsäure        diazotiert.    Man rührt, bis  eine Probe in Eiswal     ser    klar löslich ist.  Nun wird die ganze Mischung in viel Eis  wasser gegeben.

   Die so erhaltene klare       Diazolösung    vereinigt man mit einer Auf-         lösung    von 26,9 Teilen 2 .     5-Dimetboxy-l-N-          (diinethoxyäthyl)-aminobenzol    in der nötigen  Menge verdünnter Mineralsäure. Der Farb  stoff scheidet sich als dunkles Pulver aus.       Nachdem    die Kupplung durch Zusatz von       Natriumacetat    zu Ende geführt wurde, wird  filtriert und neutral gewaschen.



      Additional patent to main patent no. <B> 178224. </B> Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 2-lirylirio-5-nitro-plienylmethylsulfori is combined with 2.5 dimethoxy-1-N- (dimethoxyethyl) amirlobenzene. When dry, the dye thus obtained forms a dark powder which dissolves in organic solvents such as acetone, ethyl acetate, etc., with a bright blue-violet color.

   Finely dispersed with suitable additives, it dyes artificial silk in pure, blue-violet tones.



       Example: 21.6 parts of 2-amino-5-nitro-phenylethyl-sulfone are dissolved in about 300 parts of sulfuric acid with vigorous stirring and then diazotized by adding 8 parts of sodium nitrite or the corresponding amount of nitro-sulfonic acid. The mixture is stirred until a sample is clearly soluble in ice water. Now the whole mixture is poured into plenty of ice water.

   The clear diazo solution thus obtained is combined with a solution of 26.9 parts of 2. 5-Dimetboxy-l-N- (diinethoxyethyl) -aminobenzene in the necessary amount of dilute mineral acid. The dye separates out as a dark powder. After the coupling has been completed by adding sodium acetate, it is filtered and washed neutral.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man diazotiertes 2 - Amino - 5 - nitro -phenyl- metbylsulfon mit 2.5-Dimethoxy-l-N-(di- metlioxyäthyl)-aminoberizol vereinigt. Der so erhaltene Farbstoff bildet in. trockenem Zu stande ein dunkles Pulver, das sich in or ganischen Lösungsmitteln, wie Aceton, Essig ester usw., mit leuchtend blauvioletter Farbe löst. PATENT CLAIM: Process for the production of a new dye, characterized in that diazotized 2 - amino - 5 - nitro -phenyl-methylsulfone is combined with 2,5-dimethoxy-1-N- (dimethoxyethyl) -aminoberizole. The dye thus obtained forms a dark powder in the dry state, which dissolves in organic solvents such as acetone, ethyl acetate, etc., with a bright blue-violet color. Durch geeignete Zusätze in feine Ver teilung gebracht, färbt er Acetatkunstseide in reinen, blauvioletten Tönen. Finely distributed through suitable additives, it dyes acetate artificial silk in pure, blue-violet tones.
