Description
Verfahren zur Rerstellung eines neuen Azofarbstoffes. Es wurde gefunden, #dass, man einen neuen Azofarbstoff erhält, wenn man das diazo- tierte Diät)lylamid der 2-Aminobenzoesä.ure mit dem 2,#3-Oxynaplithopsäure-2'-met'hylani- lid vereinigt.
Der neue Farbstoff bildet ein lebhauft ge färbtes oranges Pulver. Auf geeigneten Sub straten, wie zum Beispiel Baumwolle, her gestellt, färbt er diese in echten orangen Tönen.
<I>Beispiel:</I> <B>19,1</B> Teile des Diätliylamids der 2.-Ami- nobenzoesäure werden wie übliell diazotiert und in eine Lösung von<B>27,7</B> Teilen 2,3-Oxy- napht'hoesä,ure <B>-</B> 2'- metllylanilid, 40 Teilen 30%iger Natriumhydraxydlösung, <B>15</B> Teilen Soda und<B>1000</B> Teilen Wasser eingetragen. Der gebildete Farbstoff fällt sofort aus. Der orange Niederschlag wird filtriert und ge trocknet.
Process for the preparation of a new azo dye. It has been found that a new azo dye is obtained when the diazo-tated diet) lylamide of 2-aminobenzoic acid is combined with 2, # 3-oxynaplithopic acid-2'-methylanilide.
The new dye forms a brightly colored orange powder. Produced on suitable substrates, such as cotton, he dyes them in real orange tones.
<I> Example: </I> <B> 19.1 </B> parts of the diethylamide of 2.-aminobenzoic acid are diazotized as usual and converted into a solution of <B> 27.7 </B> parts of 2 , 3-Oxynapht'hoesä, ure <B> - </B> 2'- metllylanilid, 40 parts of 30% sodium hydroxide solution, <B> 15 </B> parts of soda and <B> 1000 </B> parts Water entered. The dye formed precipitates immediately. The orange precipitate is filtered and dried.
