Description

  

  Zusatzpatent zum Hauptpatent Nr. 302913.    Verfahren zur Herstellung eines     Triphenylmethanfarbstoffes,       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Herstellung eines       Triphenylmethanfarbstoffes,    welches dadurch  gekennzeichnet ist,     dass    man auf das durch  Umsetzung eines     Resor        cin-sulfophthaleins    der  folgenden Formel:  
EMI0001.0006     
    mit einem Chlorderivat des Phosphors erhal  tene innere Salz der     3,6-Dichlor-9-phenyl-          Yanthydrol-2',4'-disulfosäure        2-Amino-1,4-di-          m.ethylbenzol-5-sulfosäure    einwirken lässt.  



       Beispiel:     16,7 Gewichtsteile 2 -     amino    -1,4 -     dimethyl-          benzol-5-sulfosaures    Natrium werden mit 35       Volumteilen        Diglykol    auf 100  C erhitzt.

   Nach  Zugabe von 8,2 Gewichtsteilen des durch Um  setzung eines     Resorcin-sulfophthaleins    der  oben angegebenen Formel mit     Phosphoroxy-          chlorid    erhaltenen innern Salzes der     3,6-Di-          chlor    - 9 -     phenylxanthydrol    -2',4'-     disulfosäure     wird sieben Stunden bei 120-125  C gerührt  und die tiefblaue Schmelze in 200     Volumteile     gesättigte Kochsalzlösung gegossen. Der ab-    geschiedene Farbstoff wird abgesaugt, aus  Wasser umgelöst und getrocknet.  



  An Stelle von     Phosphoroxychlorid    kann  auch     Phosphorpentachlorid    verwendet werden.  Das so erhaltene Produkt stellt ein violettes  Pulver dar, das Wolle in violetten Tönen von  sehr guten     Echtheitseigenschaften    färbt.



  Additional patent to main patent no. 302913. Process for the production of a triphenylmethane dye, the subject of the present additional patent is a process for the production of a triphenylmethane dye, which is characterized in that the reaction of a resorcin-sulfophthalein of the following formula
EMI0001.0006
    with a chlorine derivative of phosphorus obtained inner salt of 3,6-dichloro-9-phenyl-yanthydrol-2 ', 4'-disulfonic acid, 2-amino-1,4-dimethylbenzene-5-sulfonic acid, can act.



       Example: 16.7 parts by weight of 2-amino-1,4-dimethylbenzene-5-sulphonic acid sodium are heated to 100 ° C. with 35 parts by volume of diglycol.

   After adding 8.2 parts by weight of the inner salt of 3,6-dichloro-9-phenylxanthydrol -2 ', 4'-disulfonic acid obtained by reaction of a resorcinol sulfophthalein of the formula given above with phosphorus oxychloride, for seven hours Stirred at 120-125 C and poured the deep blue melt into 200 parts by volume of saturated saline solution. The deposited dye is filtered off with suction, redissolved in water and dried.



  Phosphorus pentachloride can also be used instead of phosphorus oxychloride. The product thus obtained is a violet powder which dyes wool in violet shades with very good fastness properties.
