Description
Verfahren zur Darstellung eines ö-Ogyazofar bstoffes. Es wurde gefunden, dass durch Kuppeln von 3 # 4 # 6-Trichlor-2-diazo-l-oxybenzol mit 2-Oxyriaplitalin-6-sulfosäure ein Farbstoff er halten wird, der mit Hilfe von Chrombeizen auf Wolle rotviolette Nuancen liefert.
<I>Beispiel:</I> Die aus 21,3 Teilen 3 # 4 # 6-Trichlor-2- amino-oxybenzol in der üblichen Weise be= reitete Diazoverbindung wird mit 24,6 Teilen 2-Oxynaphtalin-6-sulfosauremNatrium in soda= alkalischer Lösung vereinigt. Der Farbstoff wird wie bekannt aufgearbeitet.
Process for the preparation of an ö-ogyazo dye. It has been found that by coupling 3 # 4 # 6-trichloro-2-diazo-1-oxybenzene with 2-oxyriaplitalin-6-sulfonic acid, a dye is obtained which, with the help of chrome stains on wool, provides red-violet shades.
<I> Example: </I> The diazo compound prepared in the usual way from 21.3 parts of 3 # 4 # 6-trichloro-2-amino-oxybenzene is mixed with 24.6 parts of 2-oxynaphthalene-6-sulphonic acid sodium in soda = alkaline solution combined. The dye is worked up as known.
