Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass    man. einen     rieuen     Farbstoff erhält, wenn     man        diazotiertes        2-          Amitio-5-niti-o-phenyläthylsullon    mit     Äthyl-          oxyäthylaniliii    vereinigt. Der     i#o    erhaltene  Farbstoff bildet in trockenem Zustande ein  dunkles Pulver, das sich in organischen  Lösungsmitteln, wie Aceton, Essigester     usw.,     mit leuchtend blauroter Farbe löst.

   Durch  geeignete Zusätze in     fuine    Verteilung ge  bracht, färbt er     Acetatkunstseide    in reinen,       violettroten    Tönen.  



  <I>Beispiel</I>  <B>23</B> Teile     2-Amino-5-nitro-phenyläthyl-          sulfon,    erhalten     z.B.    durch Reduzieren des       Sulfochlorides    der     1-Cliloi--4-nitro-2-benzol-          sulfonsäure    mit     Natriumsulfit,    Umsetzen der  so erhaltenen     Sulfinsäure    zunächst mit     Äthyl-          bromid,und    hierauf mit Ammoniak,

   werden  unter kräftigem Rühren in etwa<B>300</B> Teilen  Schwefelsäure gelöst und darauf durch Zu  satz von<B>8</B> Teilen     Natriiiiiinitrit    oder der  entsprechenden Menge     NitrosyIschwefelsäure          diazotiert.    Man rührt, bis eine Probe in Eis  wasser klar löslich ist. Nun wird die ganze    Mischung in viel Eiswasser gegeben. Die so  erhaltene klare     Diazolösting    vereinigt man  mit einer Auflösung von<B>16,5</B> Teilen     Äthyl-          oxyäthylanilin    in der nötigen Menge ver  dünnter Mineralsäure. Der Farbstoff scheidet  sich als dunkles Pulver aus.

   Nachdem die  Kupplung durch Zusatz von     Natriumacetat          züi    Ende geführt wurde, wird filtriert und  neutral gewaschen.



  Process for the production of a new dye. It was found that one. A rough dye is obtained when diazotized 2-amitio-5-niti-o-phenylethylsullone is combined with ethyl oxyäthylaniliii. The dye obtained in the dry state forms a dark powder which dissolves in organic solvents such as acetone, ethyl acetate, etc., with a bright blue-red color.

   With suitable additives, it dyes acetate artificial silk in pure, violet-red tones when it is properly distributed.



  <I> Example </I> <B> 23 </B> parts of 2-amino-5-nitro-phenylethyl sulfone, obtained e.g. by reducing the sulfochloride of 1-Cliloi - 4-nitro-2-benzene sulfonic acid with sodium sulfite, reacting the sulfinic acid obtained in this way first with ethyl bromide, and then with ammonia,

   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 nitrosulfuric acid. 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 obtained in this way is combined with a dissolution of 16.5 parts of ethyl oxyethylaniline 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.
