Description

  

  Verfahren zur Herstellung eines     Honoazofarbstoffes.       Vorliegende Erfindung betrifft ein Ver  fahren zur Herstellung eines     Monoazofarb-          stoffes.    Das Verfahren     isst    dadurch gekenn  zeichnet,     dass    man     diazotierte   <B>1 -</B>     Amino        -          benze,#1-2-,sulfon#säure    mit     1-Phenyl-3-methyl-          5        -pyrazolon-        di-        (sulf   <B>-ss-</B>     chloräthylamid)     kuppelt.  



  Der Farbstoff stellt ein gelbes, wasser  lösliches Pulver dar     und    färbt Wolle aus  saurem Bade     grünstichig    gelb.    <I>Beispiel:</I>    <B>17,3</B>     Gewiclitsteile        1-Aminobenzol-2-sul-          foneäure    werden     diazotiert.    Die     Diazoverbin-          Jung        lässt    man in eine eiskalte,     wässrige     Suspension von 45,7     Gewiclitsteilen        1-Phenyl-          3-methyl-        5-ipyrazolon-3,

    in Gegenwart von     Natriumaoetat    einlaufen.       lst    die Kupplung beendet, wird der Farb  stoff abgetrennt und     wie    üblich fertiggestellt.  



  Er stellt ein gelbes,     wasserlösliehes     Pulver dar und färbt Wolle aus     sau-rem     Bade     gitustichig    gelb; die Färbung ist egal  und weist eine     6eUT    gute     Wasehechtheit    bei  der scharfen Wäsche auf, und zwar sowohl  bezüglich Bluten auf Weiss als auch in     der          ErhaItung        #d-es    Farbtones und der Farbtiefe.



  Process for the preparation of a honoazo dye. The present invention relates to a method for producing a monoazo dye. The process is characterized by the fact that diazotized <B> 1 - </B> amino - benzene, # 1-2-, sulfonic acid with 1-phenyl-3-methyl-5-pyrazolone-di- (sulf < B> -ss- </B> chloroethylamide) couples.



  The dye is a yellow, water-soluble powder and dyes wool from an acidic bath with a greenish yellow. <I> Example: </I> <B> 17.3 </B> parts by weight of 1-aminobenzene-2-sulphonic acid are diazotized. The Diazoverbin-Jung is left in an ice-cold, aqueous suspension of 45.7 parts by weight of 1-phenyl-3-methyl-5-ipyrazolon-3,

  5'-di- (sulf-ss-ohlor- äthylami.d,)
EMI0001.0032
    run in in the presence of sodium acetate. Once the coupling has ended, the dye is separated and finished as usual.



  It is a yellow, water-soluble powder and dyes wool from acidic baths with a cast yellow; the coloring is irrelevant and has good wash fastness in the case of sharp laundry, both in terms of bleeding on white and in the preservation of the hue and the depth of color.
