Description

  

      Terfahren    zur Herstellung eines neuen     Nonoazofarbstofes.       Die vorliegende Erfindung betrifft ein  Verfahren zur     Herstellung    eines neuen     was-          serlöslichen        Monoazofarbstoffes,    der sich zum  Färben und Drucken von     künstlicher    Acetat  seide, Wolle, Seide,     zinnbeschwerter    Seide  sowie Nylon eignet und durch Kuppeln des       diazotierten        Schwefelsäureesters    des     p-Amino-          phenyl-ss-ogyäthyläthers    mit     p-Ogydiphenyl     erhalten wird.

    



  <I>Beispiel:</I>  <B>23,3</B> Teile des     Schwefelsäureesters    des       p-Aminophenyl-ss-ogyäthyläthers    werden in  300, Teilen Wasser, enthaltend 25 Teile  36%ige Salzsäure, gelöst und durch Zuggabe  von 6,9 Teilen     Natriumnitrit        diazotiert    und  die auf 5-10  C gekühlte     Diazolösung        unter     Rühren einer     Suspension    zugesetzt, welche  durch Kochen von p -     Ogydiphenyl    mit  400 Teilen     Wasser,    enthaltend 4 Teile Na  triumhydrogyd, Kühlen auf 5-10  C und  durch Zugabe von 30 Teilen wasserfreies Na  triumcarbonat erhalten wird.

   Nachdem Rüh  ren des Gemisches bis zur beendeten Kupp-         hing    wird der Farbstoff     abfiltriert,    mit  etwas Wasser gewaschen und bei     40-50     C  getrocknet.  



  Der neue Farbstoff bildet ein mattgelbes  Pulver,     welches    in warmem Wasser     unter     Bildung einer orangegelben Lösung und in  konzentrierter Schwefelsäure unter Bildung  einer matten     scharlaehroten    Lösung löslich ist.

    Er färbt     Celluloseacetatseide    in     grünlichgel-          ben    Tönen von sehr guter Licht- und     Subli-          mationsechtheit    und von     guter        Ätzbarkeit,     sofern     das    Auffärben aus einem neutralen,       Natriumehlorid    oder Natriumsulfat enthal  tenden     Färbebade    erfolgt.



      The process of making a new nonoazo dye. The present invention relates to a process for the production of a new water-soluble monoazo dye which is suitable for dyeing and printing artificial acetate silk, wool, silk, tin-weighted silk and nylon and which is produced by coupling the diazotized sulfuric acid ester of p-aminophenyl-ss- ogyäthyläthers is obtained with p-Ogydiphenyl.

    



  <I> Example: </I> <B> 23.3 </B> parts of the sulfuric acid ester of p-aminophenyl-ss-ogyäthyläthers are dissolved in 300 parts of water containing 25 parts of 36% hydrochloric acid and, by adding 6.9 parts of sodium nitrite are diazotized and the diazo solution, cooled to 5-10 C, is added with stirring to a suspension which is obtained by boiling p-Ogydiphenyl with 400 parts of water containing 4 parts of sodium hydrogen, cooling to 5-10 C and adding 30 Parts of anhydrous sodium carbonate is obtained.

   After the mixture has been stirred until the coupling is complete, the dye is filtered off, washed with a little water and dried at 40-50.degree.



  The new dye forms a pale yellow powder, which is soluble in warm water to form an orange-yellow solution and in concentrated sulfuric acid to form a pale pear-red solution.

    It dyes cellulose acetate silk in greenish-yellow shades of very good lightfastness and sublimation fastness and good etchability, provided that the dyeing takes place from a neutral dye bath containing sodium chloride or sodium sulfate.

PATENTANSPRUCH Verfahren zur Herstellung eines neuen wasserlöslichen Monoazofarbstoffes, der sich zum Färben und Drucken von künstlicher Acetatseide, Wolle, Seide, zinnbeschwerter Seide sowie Nylon eignet, dadurch gekenn zeichnet, dass man den diazotierten Schwefel- säureester des p-Aaninophenyl-ss-oxyäthyl- äthers mit p-Oxydiphenyl kuppelt. PATENT CLAIM Process for the production of a new water-soluble monoazo dye, which is suitable for dyeing and printing artificial acetate silk, wool, silk, tin-weighted silk and nylon, characterized in that the diazotized sulfuric acid ester of p-aaninophenyl-s-oxyethyl ether is used couples with p-oxydiphenyl. Der neue Farbstoff bildet ein mattgelbes Pulver, welches in warmem Wasser unter Bildung einer orangegelben Lösung und in konzentrierter Schwefelsäure unter Bildung einer matten scharlachrotenLösung löslich ist. Er färbt Celluloseacetatseide in brünlichgel- gen Tönen von sehr guter Licht- und Subli- mationsechtheit und von guter Ätzbarkeit, sofern das Auffärben aus einem neutralen, Natriumch:lorid oder Natriumsulfat enthal tenden Färbebade erfolgt. The new dye forms a pale yellow powder that is soluble in warm water to form an orange-yellow solution and in concentrated sulfuric acid to form a pale scarlet solution. It dyes cellulose acetate silk in brownish-yellow shades of very good lightfastness and sublimation fastness and good etchability, provided the dyeing takes place from a neutral dye bath containing sodium chloride or sodium sulfate.
