Description

  

      Zusatzpatent    zum Hauptpatent Nr. 178224.    verfahren zur Herstellung eines neuen     Farbstoffes            1:s    wurde gefunden,     da,ss    man einen neuen       Farbstoff    erhält, wenn man     diazotiertes        2-          .lniino-5-nitro-phenylmethylsulfon    mit     N-          (.Äthy        1-methoxyäthyl)-aminobenzol    vereinigt.       Der    so erhaltene Farbstoff bildet in trocke  nem Zustande ein dunkles Pulver, das sich  in organischen Lösungsmitteln, wie Aceton,  Essigester usw., mit leuchtend rotvioletter  Farbe löst.

   Durch geeignete Zusätze in feine  Verteilung gebracht, färbt er     Acetatkunst-          seide    in reinen, rotvioletten Tönen.  



  <I>" Beispiel:</I>       ?1,6    Teile     2-Amino-5-nitro-phenylmethyl-          sulfon    werden unter kräftigem Rühren in  etwa 300 Teilen Schwefelsäure gelöst und  darauf durch Zusatz von 8 Teilen     NTatrium-          nitrit    oder der entsprechenden Menge     Nitro-          sylschwefelsäure    dianotiert. 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 17,9    'feilen     N-(Äthyl-methoxyäthyl)-aminobenzol     in der nötigen Menge verdünnter Mineral  säure. Der Farbstoff scheidet sich als dunk  les Pulver aus. Nachdem die Kupplung  durch Zusatz von     \atriumacetat    zu Ende  geführt wurde, wird filtriert und neutral  gewaschen.



      Additional patent to the main patent no. 178224. process for the production of a new dye 1: s has been found that a new dye is obtained if diazotized 2-nino-5-nitro-phenylmethylsulfone with N- (.ethyl 1-methoxyethyl ) -aminobenzene combined. The dye thus obtained forms a dark powder when dry, which dissolves in organic solvents such as acetone, ethyl acetate, etc., with a bright red-violet color.

   Finely distributed through suitable additives, it dyes acetate artificial silk in pure, red-violet tones.



  <I> "Example: </I>? 1.6 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 N sodium nitrite or the corresponding amount Nitrosylsulphuric acid is dianotated, stir until a sample is clearly soluble in ice water, and then pour the whole mixture into plenty of ice water.

   The clear diazo solution thus obtained is combined with a resolution of 17.9 'files N- (ethyl methoxyethyl) 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.
