Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen     Polyazofarbstoffes.       Es wurde gefunden, dass man einen  neuen metallhaltigen     Polyazofarbstoff    er  hält, wenn man 1     Mol.    des     Farbstoffes    aus 2       :

  11o1.        diazotiertem        4-Chlor-2-amino-l-phenol     und 1     Mol.    5,     5'-Dioxy-2,2'-dinaphthylamin-          7,        7'-disulfosäure    zunächst mit einer der  Hälfte der zur vollständigen     Metallisierung     notwendigen Menge eines chromabgebenden  Mittels behandelt und hierauf bis zur Ab  sättigung der     metallisierbaren    Gruppen mit  kupferabgebenden Mitteln weiterbehandelt.  



  Der neue Farbstoff ist ein schwärzliches  Pulver, das sich in Wasser, Soda und ver  dünnter Natronlauge blau, in konzentrierter       Schwefelsäure    ebenfalls blau löst. Aus neu  tralem oder     sodaa.lkalischem,        glaubers.alzhal-          tigen    Färbebad wird Baumwolle in blauen  Tönen angefärbt, welche gute Echtheits  eigenschaften aufweisen.  



  <I>Beispiel:</I>  Der aus 46,1 Teilen 5,     5'-Dioxy-2,2'-          dinaphthylamin-7,7'-disulfosäure    und 28,6    Teilen     diazotiertem        4-Chloraminophenol    her  gestellte Farbstoff wird als     Pressgut    in 6:000  Teilen heissem Wasser gelöst und mit 7,6  Teilen     Cr20,    in Form einer 7,8      /oigen    Fluor  chromlösung versetzt. Man erhitzt 24 bis 30  Stunden am     Rückflusskühler    und gibt noch  heiss 25 Teile kristallisiertes Kupfersulfat  zu und erwärmt noch einige Zeit auf 100  .  Der     ursprünglich    rote Farbstoff ist nun  blau geworden und zum grössten Teil aus  der Lösung ausgeschieden.

   Durch Zugabe  von genügend Kochsalz wird er gänzlich  ausgefällt und hierauf filtriert.



  Process for the preparation of a new metal-containing polyazo dye. It has been found that a new metal-containing polyazo dye is obtained if one mole of the dye from 2:

  11o1. diazotized 4-chloro-2-amino-1-phenol and 1 mol. 5, 5'-dioxy-2,2'-dinaphthylamine-7, 7'-disulfonic acid initially with one half of the amount of a chromium donating agent necessary for complete metallization treated and then further treated with copper-releasing agents until the metallizable groups are saturated.



  The new dye is a blackish powder that dissolves blue in water, soda and dilute caustic soda, and also blue in concentrated sulfuric acid. Cotton is dyed in blue tones, which have good fastness properties, from neutral or soda alkaline, believable salty dye bath.



  <I> Example: </I> The dye produced from 46.1 parts of 5, 5'-dioxy-2,2'-dinaphthylamine-7,7'-disulfonic acid and 28.6 parts of diazotized 4-chloraminophenol is used as a pressed material dissolved in 6,000 parts of hot water and mixed with 7.6 parts of Cr20, in the form of a 7.8% fluorine chromium solution. The mixture is refluxed for 24 to 30 hours and 25 parts of crystallized copper sulfate are added while still hot, and the mixture is heated to 100 for a while. The originally red dye has now turned blue and is largely eliminated from the solution.

   It is completely precipitated by adding enough common salt and then filtered.

PATENTANSPRUCH: Verfahren zur Herstellung eines metall haltigen Polya.zofarbstoffes, dadurch ge kennzeichnet, dass man 1 Mol. des Farbstof- fes aus 2 Mol. diazotiertem 4-Chlor-2-amino- 1-phenol und 1 Mol. 5,5'-Dioxy-2,2'-dinaph- thylamin-7,7'disulfosäure zunächst mit. PATENT CLAIM: Process for the production of a metal-containing polya.zo dye, characterized in that 1 mole of the dye is made from 2 moles of diazotized 4-chloro-2-amino-1-phenol and 1 mole. 5,5'- Dioxy-2,2'-dinaphthylamine-7,7'disulfonic acid initially with. einer der Hälfte der zur vollständigen Metallisie- rung notwendigen Menge eines chromabge- bendenMittels behandelt und hierauf bis zur Absättigung der metallisierbaren Gruppen mit kupferabgebenden Mitteln weiterbehan delt. Der neue Farbstoff ist ein schwärzliches Pulver, das sich in Wasser, Soda und ver dünnter Natronlauge blau, in konzentrierter Schwefelsäure ebenfalls blau löst. one of half of the amount of a chromium-releasing agent required for complete metallization is treated and then further treated with copper-releasing agents until the metallizable groups are saturated. The new dye is a blackish powder that dissolves blue in water, soda and dilute caustic soda, and also blue in concentrated sulfuric acid. Aus neu tralem oder sodaalkalischem, glaubersalzhal- tigen Färbebad wird Baumwolle in blauen Tönen angefärbt, welche gute Echtheits eigenschaften aufweisen. Cotton is dyed in blue tones from neutral or soda-alkaline dye bath containing Glauber's salt, which have good fastness properties.
