Description
Zusatzpatent zum Hauptpatent Nr, <B>178224.</B> Verfahren zur Ilerstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man diazotiertes 2- Amino-5-1)enzoylaminophenylmetli,vlsulfon in saurem Medium mit der 2-Amino-8-oxynaph- 1,lialin-6-sulfonsäure vereinigt. Der neue Farbstoff bildet ein dunkles Pulver, das sich in Wasser mit blauroter Farbe löst. Es färbt wolle aus saurem Bade in echten bordeaux roten Farbtönen an.
<I>Beispiel:</I> <B>0</B> Teile 2-Amino-5-benzoylaminoplienyl- iiie,thylsulfon werden unter Zugabe von Salz saure und<B>69</B> Teilen Natriumnitrit in die Nazoverbindung übergeführt. In diese Di- azolösung trägt man eine neutrale Lösung von -)39 Teilen '2)-Amino-8-oxynaphthalin-6- sulfonsäure ein und beschleunigt die Reak tion durch Zugabe von Natriumacetat. Der Farbstoff wird nun abfiltriert, <B>.</B> ausgewaschen und getrocknet.
Additional patent to main patent no, <B> 178224. </B> Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 2-amino-5-1) enzoylaminophenylmetli, vlsulfone is combined with 2-amino-8-oxynaph-1, lialine-6-sulfonic acid in an acidic medium. The new dye forms a dark powder that dissolves in water with a blue-red color. It stains wool from an acid bath in real burgundy shades.
<I> Example: </I> <B> 0 </B> parts of 2-amino-5-benzoylaminoplienyl- iiie, thylsulfon are converted into the nazo compound with the addition of hydrochloric acid and 69 parts of sodium nitrite . A neutral solution of -) 39 parts of '2) -amino-8-oxynaphthalene-6-sulfonic acid is introduced into this diazo solution and the reaction is accelerated by adding sodium acetate. The dye is then filtered off, <B>. </B> washed and dried.
