Description

  

  Verfahren zur Herstellung eines neuen     Honoazofarbstoffes.       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,     zinnbes-chv#>erter    Seide  sowie Nylon eignet und durch Kuppeln des  dianotierten     Schwefelsäureesters    des     p-Amino-          phenyl-fl-oxyäthyläthers    mit     p-n-Amylphe-          nol    erhalten wird.  



  <I>Beispiel:</I>  <B>23,3</B> Teile des     Schwefelsä,ureesters    des       p-Aminophenyl-ss-oxyäthyläthers    werden in  300 Teilen Wasser, enthaltend 25 Teile       36%ige    Salzsäure, suspendiert und bei 7  C       durch    Zugabe von 7 Teilen     Natriumnitrit,     gelöst in 50 Teilen     Wasser,    dianotiert. Hier  auf löst. man 16,4 Teile     p-n-Amylphenol    in  400 Teilen Wasser, enthaltend 4 Teile Na  triumhydroxyd, und gibt 30 Teile wasser  freies     Natriumcarbonat    zur Lösung hinzu.

    Nachdem man die Lösung auf 5-10  C ab  gekühlt hat, fügt man unter Rühren die vor-    genannte     Diazalösung    allmählich hinzu. Nach  beendeter     Kupplung    werden 40 Teile Na  triumchlorid eingetragen, worauf der ausge  fällte Farbstoff erbfiltriert und getrocknet  wird.  



  Dieser neue Farbstoff bildet ein gelbes  Pulver, welches in warmem Wasser unter  Bildung einer     rötlichgelben    Lösung und in  konzentrierter Schwefelsäure unter Bildung  einer     bräunlichroten    Lösung löslich ist. Er  färbt     Celluloseacetatseide    und Nylonfasern in  grünlich gelben Tönen von sehr guter     Licht-          und        Sublimationsechtheit.  



  Process for the production of a new honoazo 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-chv #> erter silk and nylon, and by coupling the dianotized sulfuric acid ester of p-amino- phenyl-fl-oxyäthyläthers with pn-amylphenol is obtained.



  <I> Example: </I> <B> 23.3 </B> parts of the sulfuric acid ester of p-aminophenyl-β-oxyethyl ether are suspended in 300 parts of water containing 25 parts of 36% strength hydrochloric acid and at 7 C by adding 7 parts of sodium nitrite dissolved in 50 parts of water, dianotized. Solve here. 16.4 parts of p-n-amylphenol in 400 parts of water containing 4 parts of sodium hydroxide, and 30 parts of anhydrous sodium carbonate are added to the solution.

    After the solution has cooled to 5-10 ° C., the aforementioned diazo solution is gradually added with stirring. After the coupling is complete, 40 parts of sodium chloride are entered, whereupon the precipitated dye is erbfiltered and dried.



  This new dye forms a yellow powder which is soluble in warm water to form a reddish-yellow solution and in concentrated sulfuric acid to form a brownish-red solution. It dyes cellulose acetate silk and nylon fibers in greenish yellow tones with very good light and sublimation fastness.
