Description

  

  Verfahren zur     Herstellung    eines     Nüpenfarbstoffes.       Das Hauptpatent betrifft ein Verfahren  zur     Herstellung    eines     Küpenfarbstoffes,     bei dem man     1(N),2-Pyrazoloanthraehinon-          PyC-carbonsäurechlorid    mit     1-Aminoanthra-          chinon    umsetzt.  



  Es wurde nun gefunden, dass man eben  falls einen wertvollen     Küpenfarbstoff    erhält,  wenn man etwa 1     Mol        PyC-Phenyl-1(N),2-          pyrazoloanthrachinon        -4'-carbonsäurechlorid     mit     etwa    1     Mol        1,5-Diaminoanthrachinon    um  setzt und die erhaltene Verbindung mit       Benzoylchlorid    behandelt.  



  Der neue Farbstoff färbt Baumwolle aus  brauner     Küpe    in echten gelben Tönen.    <I>Beispiel:</I>    Zu einer auf<B>150'</B> C erwärmten Lösung  von 12 Teilen     1,5-Diaminoanthrachinon    in  500 Teilen     Nitrobenzol    gibt man 19 Teile       PyC-Phenyl-1(N),        2-pyrazoloanthrachinon-4'-          carbonsäurechlorid    und erwärmt das Gemisch  noch 5     Stunden    lang auf     150-bis    155   C. Die  erhaltene Verbindung,     in    der noch eine freie         Aminogruppe    vorhanden ist, saugt man bei  100   C ab, wäscht sie aus und trocknet sie.

    Dann erhitzt man ein Gemisch von 5 Teilen  dieser     Verbindung,    5 Teilen     Benzoylchlorid     und 50 Teilen     Nitrobenzol    3     Stunden    lang  auf 170 bis 180   C, saugt dann den entstan  denen Farbstoff bei 100   C ab, wäscht ihn  aus und     trocknet    ihn. Er färbt Baumwolle  aus brauner     Küpe    in echten gelben Tönen.



  Process for the production of a pebble dye. The main patent relates to a process for the production of a vat dye in which 1 (N), 2-pyrazoloanthraehinone-PyC-carboxylic acid chloride is reacted with 1-aminoanthraquinone.



  It has now been found that a valuable vat dye is also obtained if about 1 mol of PyC-phenyl-1 (N), 2-pyrazoloanthraquinone -4'-carboxylic acid chloride is reacted with about 1 mol of 1,5-diaminoanthraquinone and the resulting Compound treated with benzoyl chloride.



  The new dye dyes cotton from a brown vat in real yellow tones. <I> Example: </I> To a solution, heated to <B> 150 '</B> C, of 12 parts of 1,5-diaminoanthraquinone in 500 parts of nitrobenzene, 19 parts of PyC-phenyl-1 (N), 2 -pyrazoloanthraquinone-4'-carboxylic acid chloride and the mixture is heated to 150 to 155 ° C. for a further 5 hours. The compound obtained, in which one free amino group is still present, is filtered off with suction at 100 ° C., washed and dried.

    A mixture of 5 parts of this compound, 5 parts of benzoyl chloride and 50 parts of nitrobenzene is then heated at 170 to 180 ° C. for 3 hours, then the resulting dye is filtered off with suction at 100 ° C., washed off and dried. He dyes cotton from a brown vat in real yellow tones.
