Description

  

  Verfahren zur Herstellung eines neuen     Honoazofarbstoifes.       Die vorliegende Erfindung betrifft ein  Verfahren zur     Herstellung    eines     neuen.    was  serlöslichen     Monoazofarbstoffes.,    der sich zum  Färben und     Drucken    von     künstlicher        A.cetat-          seide,    Wolle, Seide,

       zinnbeschwerter    Seide  sowie Nylon eignet und durch Kuppeln des       diazotierten        Schwefelsäureesteas    des     p-Amino-          phenyl-y-oxypropyläthers    mit     p-Oxydiphe-          nyl        erhallten    wird.

      <I>Beispiel:</I>  24,7 Teile des     Schwefelsäureesters    des       p-Aminophenyl-y-oxypropyläthers    werden in       3-00    Teilen Wasser, enthaltend 25 Teile  36     %ig-e    Salzsäure, gelöst und durch Zugabe  von 6,9 Teilen     Natriumnitrit        diazotiert    und  ,die auf 5-10  C gekühlte     Diazolösung        unter     Rühren einer     Suspension    zugesetzt, welche  durch Kochen von p -     Oxydiphenyl    mit  400 Teilen Wasser, enthaltend 4 Teile Na  triumhydrogyd,

   durch Kühlen auf 5-10  C  und Zugabe von 30 Teilen     wasserfreiem        Na-          triumcarbonat    erhalten wird. Nach dem Rüh-         ren    des Gemisches bis zur beendeten Kupp  lung wird der Farbstoff     abfiltriert,    mit  wenig 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     scharlachroten    Lösung löslich  ist. Er färbt     Cellluloseacetatseide    in     grünlich-          gelben    Tönen von sehr guter Licht- und       Sublimationsechtheit    und     guter        Ätzbarkeit,     sofern das Auffärben aus einem neutralen,       Natriumchlorid    oder     Natriumsulfat    enthal  tenden Färbebade erfolgt.



  Process for the production of a new honoazo dye. The present invention relates to a method for producing a new one. what is soluble monoazo dye, which is suitable for dyeing and printing artificial acetate silk, wool, silk,

       Tin-weighted silk and nylon are suitable and are obtained by coupling the diazotized sulfuric acid ester of p-aminophenyl-y-oxypropyl ether with p-oxydiphenyl.

      <I> Example: </I> 24.7 parts of the sulfuric acid ester of p-aminophenyl-γ-oxypropyl ether are dissolved in 3-00 parts of water containing 25 parts of 36% hydrochloric acid, and 6.9 parts are added Sodium nitrite is diazotized and the diazo solution, cooled to 5-10 C, is added with stirring to a suspension which is obtained by boiling p-oxydiphenyl with 400 parts of water containing 4 parts of sodium hydrogen.

   is obtained by cooling to 5-10 ° C. and adding 30 parts of anhydrous sodium carbonate. 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 ° C.



  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 scarlet 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 Ilers.tellung 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-Aminophenyl-y-oxypropyl- äthers mit p-Oxydiphenyl kuppelt. PATENT CLAIM: Process for the preparation 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 diazotised sulfuric acid ester of p-aminophenyl-y -oxypropyl- ether 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 schatlachroten Lösung löslich ist. Er färbt Celluloseacetatseide in brünlich- gelben Tönen von sehr guter Licht- und Sublimationsechtheit und guter Ätzbarkeit. sofern das Auffärben aus einem neutralen. Natriumchlorid oder Natriumsulfat enthal tenden Färbebade erfolgt. The new dye forms a dull yellow powder, which is soluble in warm water to form an orange-yellow solution and in concentrated sulfuric acid to form a dull, shade-red solution. It dyes cellulose acetate silk in brownish-yellow shades of very good light and sublimation fastness and good etchability. provided the coloring from a neutral. Dye bath containing sodium chloride or sodium sulfate is carried out.
