Description

  

  Verfahren zur Herstellung eines     Diazotierungsfarbstoffes.       Es wurde gefunden, dass durch Kuppeln  von einem     Mol.    des     tetrazotierten        3:3'-Di-          amino-4:4'-ditolylmethans    mit 2     Mol.    der     N-          Methyl-cu-sulfosäure    der     2-(in-Amino-benzoyl)-          amino-5-oxynaphtalirr-7-sulfosäure    ein leicht  löslicher Farbstoff erhalten wird, welcher     ur-          gebeizte    Baumwolle     gelbstichig    rot färbt.

    Durch     Diazotieren    der Färbung und Kuppeln  mit     p-Naphtol    wird ein sehr waschechtes,  volles,     gelbstichiges    Rot erhalten.  



  <I>Beispiel:</I>  22,6 Teile 3:     3'-Diainino-4    :     4'-ditolylmethaii     werden in 50     Voluni-Teilen        Salzsäure        it        30"/,1"     und 200 Teilen Wasser gelöst und     finit    13,8  Teilen     Natriumnitrit        tetrazotiert.    Die     Tetrazo-          lösung    gibt man zu einer wässerigen Lösung  von 90,6 Teilen     N-Methyl-co-snlfosäure    der  2-     (m-Aminobenzoyl)

      -     aniino-        5-oxyiiaphtal    in-7-         sulfosäure    und 60 Teilen     calcinierter    Soda.  Nach beendigter Kupplung wird     ausgesalzen,     filtriert und     getrochnet.  



  Process for the preparation of a diazotization dye. It was found that by coupling one mole of the tetrazotized 3: 3'-di-amino-4: 4'-ditolylmethane with 2 moles of the N-methyl-cu-sulfonic acid of the 2- (yn-amino-benzoyl) - amino-5-oxynaphthalene-7-sulfonic acid, a readily soluble dye is obtained which dyes primed cotton in a yellowish red.

    By diazotizing the dye and coupling with p-naphtol, a very washfast, full, yellowish red is obtained.



  <I> Example: </I> 22.6 parts of 3: 3'-diainino-4: 4'-ditolylmethaii are dissolved in 50 parts by volume of hydrochloric acid with 30 "/, 1" and 200 parts of water and finite 13.8 Share sodium nitrite tetrazotized. The tetrazo solution is added to an aqueous solution of 90.6 parts of N-methyl-co-sulfonic acid of 2- (m-aminobenzoyl)

      - Aniino-5-oxyiiaphthalene-7-sulfonic acid and 60 parts of calcined soda. When the coupling is complete, it is salted out, filtered and dried.
