Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 178224.    Verfahren zur Herstellung eines neuen Farbstoffes.         II's    wurde gefunden, dass man einen neuen       harfistoff    erhält, wenn man     dia,zotiertes        2-          Aiiiino-5-tiitro-phenylmethylsulfon    mit     2-          Mclhoxy-5-methyl-1.        -N-(di-methoxy        ä,thyl        )-          aniinobenzol    vereinigt.

   Der so erhaltene  Farbstoff bildet in trockenem Zustande ein       dunkles    Pulver, das sich in organischen     Lö-          snngsinitteln.    wie Aceton, Essigester usw.,  mit leuchtend rotvioletter Farbe löst. Durch       ;ee          ig-nete    Zusätze in feine Verteilung     ge-          br,icht,    färbt er     Acetatkunstseide    in reinen,  violetten Tönen.  



  <I>Beispiel:</I>       ?1,h    Teile     ?-Amino-5-nitro-phenylmethyl-          snlfon    werden unter kräftigem Rühren in       etwa        3()(l    Teilen     Schwefelsäure    gelöst und  darauf durch Zusatz von 8 Teilen Natrium-'       nit:rit    oder der     entsprechenden    Menge     Nitro-          sj#Ischwefelsäure    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 25,3    Teilen     2-Methoxy-5-methyl-l-N-(di-methoxy-          äthyl)-aminobenzol    in der nötigen Menge  verdünnter Mineralsäure. Der Farbstoff  scheidet sich als dunkles Pulver aus. Nach  dem die Kupplung durch Zusatz von       Natriumacetat    zu Ende geführt wurde, wird  filtriert und neutral gewaschen.



  <B> Additional patent </B> to main patent no. 178224. Process for the production of a new dye. II's has been found that a new hardener is obtained if one dia, zotierten 2-Aiiiino-5-tiitro-phenylmethylsulfon with 2-methyl-5-methyl-1. -N- (di-methoxy ä, thyl) - aniinobenzene combined.

   When dry, the dye thus obtained forms a dark powder which dissolves in organic solvents. like acetone, ethyl acetate, etc., dissolves with a bright red-violet color. Finely distributed through suitable additives, it dyes acetate artificial silk in pure, violet tones.



  <I> Example: </I>? 1, h parts of? -Amino-5-nitro-phenylmethyl-snlfon are dissolved in about 3 () (l parts of sulfuric acid) with vigorous stirring and then by adding 8 parts of sodium-nit The mixture is then added to a large amount of ice water and the mixture is poured into a large amount of ice water.

   The clear diazo solution thus obtained is combined with a solution of 25.3 parts of 2-methoxy-5-methyl-1-N- (dimethoxy-ethyl) -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, the mixture is filtered and washed neutral.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man dianotiertes 2.-Amino-5-nitro-phenyl- methylsulfon mit 2-Methoxy-5-methyl-l-N- (di - 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, violetten Tönen. PATENT CLAIM: Process for the production of a new dye, characterized in that dianotated 2.-amino-5-nitro-phenyl-methylsulfone is combined with 2-methoxy-5-methyl-1-N- (dimethoxyethyl) aminobenzene.
