Description

  

  Zusatzpatent zum Hauptpatent Nr. 117996.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man das     2-Amino-l-          oxybenzol-4-sulfamid        diazotiert,    hierauf mit       1-Phenyl-3-methyl-5-pyrazolon    kuppelt und  den so erhaltenen Farbstoff mit     Alkalichro-          miten    behandelt.

   Der neue Farbstoff bildet  ein     orangebraunes    Pulver, löst sich in Was  ser und in verdünnter Natronlauge mit oran  ger, in konzentrierter     Schwefelsäure    mit gel  ber Farbe und färbt Wolle aus saurem Bade  in orangen Tönen mit vorzüglichen     Eigen-          sehaften.            Beispiel       18,8 Teile     2-Amino-l-oxybenzol-4-sulfa-          mid    werden in üblicher Weise mit 6,9 Teilen       Natriumnitrit        diazotiert.    Die     Diazolösung          lä.sst    man in eine eiskalte Lösung von 17,

  5  Teilen     1-Phenyl-3-methyl-5-pyra.zolon    und  30 Teilen Soda in 250 Teilen Wasser unter  Rühren einfliessen. Die Reaktionsmasse wird  nach vollendeter Kupplung auf 50   ange  wärmt und der Farbstoff mit Kochsalz     aus-          0-lesalzen    und wie üblich isoliert.    35,7 Teile des so erhaltenen Farbstoffes  werden in eine kochende Lösung enthaltend  8,5 Teile     Cr2O3,    150 Teile Wasser, 28 Teile       Atzkali    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  Neutralisieren und     Aussa.lzen    isoliert.



  Additional patent to main patent no. 117996. Process for the production of a new dye. It has been found that a new dye is obtained if the 2-amino-l-oxybenzene-4-sulfamide is diazotized, then coupled with 1-phenyl-3-methyl-5-pyrazolone and the dye thus obtained with alkali chromites treated.

   The new dye forms an orange-brown powder, dissolves in water and in dilute caustic soda with orange, in concentrated sulfuric acid with a yellow color and dyes wool from acid baths in orange tones with excellent properties. Example 18.8 parts of 2-amino-1-oxybenzene-4-sulfamide are diazotized in the customary manner with 6.9 parts of sodium nitrite. The diazo solution is poured into an ice-cold solution of 17,

  Pour 5 parts of 1-phenyl-3-methyl-5-pyra.zolon and 30 parts of soda in 250 parts of water with stirring. After coupling is complete, the reaction mass is warmed to 50 and the dyestuff is salted out with sodium chloride and isolated as usual. 35.7 parts of the dye thus obtained are introduced into a boiling solution containing 8.5 parts of Cr2O3, 150 parts of water, 28 parts of caustic potash and 10 parts of glycerine 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 neutralization and salting out.
