Description

  

  Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen  neuen Farbstoff erhält, wenn man das       ?-Amino-l-oxybenzol-4-sulfamid    dianotiert,  hierauf mit     1-(3'-Sulfamido)-phenyl-3-me-          thyl-5-pyrazolon    kuppelt und den so erhalte  nen Farbstoff mit     Alkalichromiten    behan  delt. Der neue Farbstoff bildet ein orange  braunes Pulver, löst sich in Wasser und in  verdünnter Natronlauge mit oranger, in kon  zentrierter Schwefelsäure mit gelber Farbe  und färbt Wolle aus saurem Bade in orangen  Tönen mit vorzüglichen Eigenschaften.  



       Beispiel     18,8 Teile     2-Amino-l-oxybenzol-4-sulfa-          inid    werden in 600 Teilen Wasser und 150  Teilen 30     %iger    Salzsäure gelöst, bei 5   mit  69 Teilen     Natriumnitrit    dianotiert und in  eine eiskalte, dauernd     sodaalkalisch.    gehal  tene Lösung von     \?53    Teilen     1-(3'-Sulfa-          mido)-phenyl-3-methyl-5-pyrazolon    einge  rührt.

   Nach beendeter     Reaktion    wird der  völlig ausgeschiedene Farbstoff     abfiltriert.     Er kann durch Lösen in Wasser bei 85 bis  90   und     Auskristallisierenlassen    gereinigt       --        -^rden.       89,9 Teile des so erhaltenen Farbstoffes  werden in eine kochende Lösung enthaltend  8,5 Teile     Cr203,    150 Teile Wasser, 28 Teile       Ätzkali    und 10 Teile Glyzerin     eingetragen     und längere Zeit gekocht. Nach Verdünnen  mit 200 Teilen Wasser wird filtriert und der  neue Farbstoff aus dem Filtrat durch Neu  tralisieren und     Aussahen    isoliert.



  Process for the production of a new dye. It has been found that a new dye is obtained if the α-amino-1-oxybenzene-4-sulfamide is dianotated and then coupled with 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone and treated the dye thus obtained with alkali chromites. The new dye forms an orange-brown powder, dissolves in water and in dilute sodium hydroxide solution with orange, in concentrated sulfuric acid with yellow color and dyes wool from acid baths in orange shades with excellent properties.



       EXAMPLE 18.8 parts of 2-amino-1-oxybenzene-4-sulfa inide are dissolved in 600 parts of water and 150 parts of 30% strength hydrochloric acid, dianotized with 69 parts of sodium nitrite at 5 and converted to an ice-cold, permanently alkaline soda. The held solution of \? 53 parts of 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone was stirred in.

   When the reaction has ended, the completely separated dye is filtered off. It can be purified by dissolving it in water at 85 to 90 and allowing it to crystallize. 89.9 parts of the dye thus obtained are introduced into a boiling solution containing 8.5 parts of Cr 2 O 3, 150 parts of water, 28 parts of caustic potash and 10 parts of glycerol and boiled for a long time. After dilution with 200 parts of water, the mixture is filtered and the new dye is isolated from the filtrate by neutralizing and looking.
