Description

  

  Verfahren zur Herstellung eines     Honoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Monoazo-          farbstoffes,    dadurch gekennzeichnet, dass     mau          diazotierte        1-Aminoberizol-2-sulfonsäui-e    mit       1-(,Q-Clilorpropioriylami        no)        -6-oxynaphthali        n-4-          sulforisäure    kuppelt.  



  Der so erhaltene Farbstoff ist ein wasser  lösliches Totoranges Pulver und färbt Wolle  aus saurem Bade in klaren     Orangetönen    von  hervorragender Lichtechtheit und guter     Wasch-          und    Schweissechtheit.  



  <I>Beispiel:</I>  17,3 Teile     1-Aminobenzol-2-sulforisäure     werden in der üblichen Weise     diazotiert    und  die erhaltene     Diazolösung    wird mit einer über  schüssiges     Natriumcarbonat    enthaltenden Lö  sung von 34 Teilen 1-(fl-Clilorpropioriylamir)o)-         6-oxynaphthalin-4-sulfonsäure    vereinigt. Nach  beendeter     Kuppelung    wird der- gebildete Farb  stoff abgeschieden und getrocknet.



  Process for the preparation of a honoazo dye. The present patent relates to a process for the production of a monoazo dye, characterized in that mau couples diazotized 1-aminoberizole-2-sulfonic acid with 1- (, Q-Clilorpropioriylamino) -6-oxynaphthalene-4-sulfonic acid.



  The dyestuff thus obtained is a water-soluble Totorange powder and dyes wool from an acid bath in clear orange shades of excellent lightfastness and good fastness to washing and perspiration.



  <I> Example: </I> 17.3 parts of 1-aminobenzene-2-sulforic acid are diazotized in the usual way and the resulting diazo solution is mixed with a solution of 34 parts of 1- (fl-Clilorpropioriylamir) o ) - 6-oxynaphthalene-4-sulfonic acid combined. When the coupling is complete, the dye formed is deposited and dried.
