Description

  

  <B>Zusatzpatent</B> zum- Hauptpatent Nr. 198713.    Verfahren zur Darstellung eines     ehromierbaren        Farbstoffes    der     Triarylmethanreihe.            Gegenstand        dieses        Zusatzpatentes        ist    ein  Verfahren     zurr        Darstellung        eines    chromier  baren     Farbstoffes    der     Triarylmethanreihe,     welches dadurch     gekennzeichnet    ist, dass man  3 -     (Äthylsulfoäthyl    -     ämino)

      - 4 -     m@ethylphenol     mit     5-O$ytrimellitheäureanhydrid    konden  siert.  



  <I>Beispiel:</I>  140     Gewichtsteile        des        Natriumsalzes        des     3-     (Äthylsulfoäthyl-amino)    -     4-metliylphenole     von der Formel:

    
EMI0001.0024     
    und     2'10        Gewichtsteile        5-Ogytrimellithsäure-          anhydrid    werden bei     200-2,10'C    zwei Stun  den     verschmolzen.    Die     pulverisierte    Schmelze  wird in 1000     Gewichtsteile        Wasser        ein-          gerührt    und mit     200,

  Gewichtsteilen        Calcium-          hydrogyd        versetzt.    Nach     1/2-stündigem    Rüh  ren     wird        abgesaugt        und    der     Rückstand    mit  warmem     Wasser        naohgewas@chen.        Das        Filtrat          wird    mit     iSchwefelsäure    schwach     kongosauer          gestellt,    auf     etwa    100     Volumteile    eingeengt,

    vom ausgeschiedenen-     C@aleiumsulfat    erb  filtriert     und        mit,dem    doppelten Volumen     ge-          sättigter        Kochsalzlösung    versetzt:

   Beim     Ehr-          kalten,    scheidet sich !der     Farbstoff        in    roten       Flocken    aus, die     sich        leicht        absaugen        lassen.     Der Farbstoff hat die     Formel:       
EMI0002.0001     
    Er färbt Wolle aus saurem Bade in klaren  roten Tönen, .die     naohohromiert        etwas    blau  stichiger sind und dann sehr gute     Echtheits-          eigenschaften        aufweisen.  



  <B> Additional patent </B> to the main patent No. 198713. Process for the preparation of an honorable dye of the triarylmethane series. The subject of this additional patent is a process for the representation of a chromable dye of the triarylmethane series, which is characterized in that 3 - (ethylsulfoethyl - ämino)

      - 4 - m @ ethylphenol condensed with 5-O $ ytrimellitheic anhydride.



  <I> Example: </I> 140 parts by weight of the sodium salt of 3- (ethylsulfoethyl-amino) -4-methylphenols of the formula:

    
EMI0001.0024
    and 2'10 parts by weight of 5-ogytrimellitic anhydride are fused at 200-2.10'C for two hours. The pulverized melt is stirred into 1000 parts by weight of water and

  Parts by weight of calcium hydrogyd added. After 1/2 hour stirring, the mixture is filtered off with suction and the residue is washed down with warm water. The filtrate is made weakly Congo acidic with iSulfuric acid, concentrated to about 100 parts by volume,

    filtered from the precipitated C @ aleium sulfate erb and treated with twice the volume of saturated saline solution:

   When it is really cold, the dye separates out in red flakes, which can be easily sucked off. The dye has the formula:
EMI0002.0001
    It dyes wool from an acid bath in clear red tones, which are slightly blue-tinged when near-eared and then have very good fastness properties.
