Description

  

  Zusatzpatent zum Hauptpatent Nr. 296001.    Verfahren     zur    Herstellung eines     Vinylsulfonfarbsto$es.       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Herstellung eines       Vinylsulfonfarbstoffes,    welches dadurch ge  kennzeichnet ist, dass man 2     Mol    der     Diazo-          niumverbindung    aus 1-Aminophenyl-4-vinyl-         sulfon    zunächst in stark saurem, dann     in     schwach essigsaurem     Mediiun    mit 1     Mol        1-          Amino-8-oxynaphthalin-3,6-disulfonsäure    kup  pelt.

           Beispiel:       36,6 Gewichtsteile     1-Aminophenyl-4-vinyl-          sulfon    werden in der üblichen Weise     diazo-          tiert    und mit einer wässerigen Lösung von  40,15 Gewichtsteilen     1-Amino-8-oxynaphtha-          lin-3,6-distrlfonsäure    bei 0-5  C vereinigt.    Nach einstündigem Verrühren wird mit einer  wässerigen Lösung von     Natriumacetat    so lange  versetzt, bis keine     Diazoniumverbindung    mehr  nachweisbar ist.

   Nach beendeter Kupplung  wird der     Vinylsul.fonfarbstoff    der Formel:  
EMI0001.0023     
         durch    Zugabe von Kochsalz abgeschieden, ab  gesaugt, mit Kochsalzlösung gewaschen und  getrocknet.  



  Das so erhaltene Produkt stellt ein schwar  zes Pulver dar, das sich in Wasser mit dun  kelblauer Farbe löst und Wolle in schwarz  blauen Tönen von guten Echtheitseigenschaf  ten färbt..



  Patent supplement to main patent No. 296001. Process for the production of a vinyl sulfone dye. The subject of the present additional patent is a process for the production of a vinyl sulfone dye, which is characterized in that 2 mol of the diazonium compound from 1-aminophenyl-4-vinyl sulfone is initially in a strongly acidic, then in a weakly acetic acid medium with 1 mol 1- Amino-8-oxynaphthalene-3,6-disulfonic acid kup pelt.

           Example: 36.6 parts by weight of 1-aminophenyl-4-vinylsulfone are diazotized in the usual manner and treated with an aqueous solution of 40.15 parts by weight of 1-amino-8-oxynaphthalin-3,6-distrulfonic acid at 0 -5 C combined. After stirring for one hour, an aqueous solution of sodium acetate is added until the diazonium compound can no longer be detected.

   When the coupling is complete, the vinyl sulphon dye of the formula:
EMI0001.0023
         deposited by adding sodium chloride, sucked off, washed with sodium chloride solution and dried.



  The product obtained in this way is a black powder which dissolves in water with a dark blue color and dyes wool in black and blue tones with good fastness properties.

PATENT CLAIM Process for the production of a vinyl sulfone dye, characterized in that 2 112o1 of the diazonium compound from 1-aminophenyl-4-vinyl sulfone is first in a strongly acidic medium, then in a weakly acetic acid medium with 1 mol of 1-amino-8-oxy-naphthalene-3 , 6-disulphonic acid couples. The product thus obtained is a black powder which dissolves in water with a dark blue color and dyes wool in black-blue shades with good fastness properties.
