      Zusatzpatent    zum Hauptpatent Nr. 178224.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     da.ss    man einen neuen  Farbstoff erhält, wenn man     diazotiertes        2-          Amino-5-nitro-phenylmethylsulfon    mit     N-          (di-oxäthyl)-aminobenzol    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 rubinroter Farbe       iö    st.

   Durch geeignete Zusätze in feine Ver  teilung gebracht, färbt. er     Acetatkunstseide     in reinen. rubinroten Tönen.  



  <I>Beispiel:</I>  21,6 Teile     2-Amino-5-nitro-phenylmethyl-          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-          svlschwefelsäure        diazotiert.    Man rührt, bis  eine Probe in Eiswasser klar löslich ist. Nun  wird die ganze Mischung in viel Eiswasser  gegeben. Die so erhaltene klare     Diazolösung     vereinigt man mit einer Auflösung von 16,5    Teilen     N-(di-oxäthyl)-aminobenzol    in der  nötigen Menge verdünnter     1Vlineralsäure.    Der  Farbstoff 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. 178224. Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 2-amino-5-nitro-phenylmethylsulfone is combined with N- (di-oxethyl) aminobenzene. The dye thus obtained forms a dark powder when dry, which dissolves in organic solvents such as acetone, ethyl acetate, etc., with a bright ruby red color.

   Finely distributed with suitable additives, colors. he acetate rayon in pure. ruby red tones.



  <I> Example: </I> 21.6 parts of 2-amino-5-nitro-phenylmethylsulfone are dissolved in about 300 parts of sulfuric acid with vigorous stirring and then by adding 8 parts of sodium nitrite or the corresponding amount of nitro-sulfosulfuric acid diazotized. The mixture is stirred until a sample is clearly soluble in ice water. Now the whole mixture is poured into a lot of ice water. The clear diazo solution thus obtained is combined with a solution of 16.5 parts of N- (di-oxethyl) aminobenzene in the necessary amount of dilute 1-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.

Der so erhaltene Farbstoff bildet in trockenem Zustande ein dunkles Pulver, das sich in organischen Lösungsmit teln, wie Aceton, Essigester usw., mit leuch tend rubinroter Farbe löst. Durch geeignete Zusätze in feine Verteilung gebracht, färbt er Acetatkunstseide in reinen, rubinroten Tönen. PATENT CLAIM Process for the production of a new dye, characterized in that diazotized 2-amino-5-nitro-phenyl-methylsulfone is combined with N - (di-oxethyl) -amino-benzene. The dye thus obtained forms a dark powder when dry, which dissolves in organic solvents such as acetone, ethyl acetate, etc., with a luminous ruby red color. Finely distributed through suitable additives, it dyes acetate artificial silk in pure, ruby red tones.
