Description

  

      Zusatzpatent        zurr    Hauptpatent Nr. 198713.    Verfahren zur Darstellung eines     chromierbaren    Farbstoffes der     Triarylmethanreihe.       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Darstellung eines       chromierbaren        Farbstoffes    der     Triarylmethan-          reihe,    welches dadurch gekennzeichnet ist,  dass man     Äthyl-p-sulfäthylamino-m-phenol    mit       5-Bromtrimellithsäureanhydrid    kondensiert  und dann in Gegenwart von Wasser das  Bromatom gegen die     Hydroxylgruppe    aus  tauscht.  



  Der so erhaltene     Farbstoff    stellt ein rotes  Pulver dar; er ist leicht in Wasser löslich  und färbt die tierische Faser aus saurem  Bade in gelbroten Tönen. Durch     Nachchro-          mieren    wird der Farbton etwas rotstickiger.       Beispiel:     26 Gewichtsteile     Äthyl-p-sulfäthylamino-          m-phenol    (erhältlich z. B. durch Umsetzung  von     m-Äthylaminophenol    mit     @-chloräthan-          sulfonsaurem    Natrium in Wasser), 82 Ge  wichtsteile     5-Bromtrimellithsäureanhydrid    und    15 Gewichtsteile Chlorzink werden einige  Stunden, z.

   B. vier Stunden, bei 225   C unter  Rühren erhitzt. Die erkaltete und fein pul  verisierte     Schmelze    wird mehrmals mit je  200 Gewichtsteilen Äthylalkohol kalt verrührt,  wobei der reine     Farbstoff    zurückbleibt.  



  Um das Bromatom gegen die     Ilydroxyl-          gruppe    auszutauschen, werden 7,8 Gewichts  teile des so erhaltenen     Farbstoffes    in etwa  5      /oigem        wässrigem        Piperidin    unter Zusatz  von je einem Gewichtsteil     gupferchlorür    und  Kupferpulver im     Autoklaven    mehrere Stunden,  z. B. fünf     Stunden,    auf     145-1501    C erhitzt.  Die filtrierte Lösung wird eingedampft und  im Vakuum bei 100   C getrocknet.

   Der so  erhaltene     Farbstoff    stellt ein rotes Pulver dar,  ist leicht in Wasser löslich und färbt die tie  rische Faser aus saurem Bade in gelbrotem  Ton.     Nachchromiert    wird der Farbton etwas  rotstickiger; die Echtheitseigenschaften sind  sehr gut.



      Additional patent to main patent no. 198713. Process for the preparation of a chromable dye of the triarylmethane series. The subject of the present additional patent is a process for the preparation of a chromable dye of the triarylmethane series, which is characterized in that ethyl-p-sulfäthylamino-m-phenol is condensed with 5-bromotrimellitic anhydride and then the bromine atom against the hydroxyl group in the presence of water exchanges.



  The dye thus obtained is a red powder; it is easily soluble in water and colors the animal fibers from acid baths in yellow-red shades. After chrome plating, the color becomes a little redder. Example: 26 parts by weight of ethyl-p-sulfäthylamino-m-phenol (obtainable e.g. by reacting m-ethylaminophenol with sodium chloroethane sulfonic acid in water), 82 parts by weight of 5-bromotrimellitic anhydride and 15 parts by weight of zinc chloride are required for a few hours, z.

   B. four hours, heated at 225 C with stirring. The cooled and finely pulverized melt is stirred several times with 200 parts by weight of ethyl alcohol each time, leaving the pure dye behind.



  In order to exchange the bromine atom for the Ilydroxyl- group, 7.8 parts by weight of the dye thus obtained in about 5 /% aqueous piperidine with the addition of one part by weight of gupferchlorür and copper powder in the autoclave for several hours, for. B. five hours, heated to 145-1501 C. The filtered solution is evaporated and dried at 100 ° C. in vacuo.

   The dye thus obtained is a red powder, is easily soluble in water and dyes the animal fiber from acid bath in a yellow-red tone. After chrome-plating, the color becomes a bit redder; the fastness properties are very good.
