Description
Zusatzpatent zum Hauptpatent Nr. <B>152883.</B> Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff der Formel
EMI0001.0005
erhält, wenn man den 4,4'-Dichlor-2-diazo-1,1'- diphenyläther mit dem 2-Methyl-4-methoxy- anilid der 2,3-Oxynaphthoesäure kuppelt. Der so erhaltene Farbstoff bildet ein hellrotes Pulver. Auf geeigneten Substraten, wie zum Beispiel Baumwolle, hergestellt, färbt er diese in leuchtenden, ausserordentlich echten Tönen.
<I>Beispiel:</I> 25,4 Teile 4,4'-Dichlor-2-amino-1,1'-phenyl- äther werden wie üblich diazotiert und in eine Lösung von<B>30,7</B> Teilen des 2-Methyl- 4-methoxy-anillds der 2,3-Oxynaphthoesäure, <B>60</B> Teilen<B>30</B> '/oiger Natronlauge,<B>15</B> Teilen Soda und 2000 Teilen Wasser eingetragen. Der gebildete Farbstoff fällt sofort aus. Er wird filtriert, gewaschen und getrocknet.
Additional patent to main patent no. <B> 152883. </B> Process for the production of a new azo dye. It has been found that a new azo dye of the formula
EMI0001.0005
obtained when the 4,4'-dichloro-2-diazo-1,1'-diphenyl ether is coupled with the 2-methyl-4-methoxyanilide of 2,3-oxynaphthoic acid. The dye thus obtained forms a light red powder. Produced on suitable substrates, such as cotton, for example, he dyes them in bright, extraordinarily real tones.
<I> Example: </I> 25.4 parts of 4,4'-dichloro-2-amino-1,1'-phenyl ether are diazotized as usual and converted into a solution of <B> 30.7 </ B > Parts of the 2-methyl-4-methoxy-anilide of 2,3-oxynaphthoic acid, <B> 60 </B> parts <B> 30 </B> '/ o of sodium hydroxide solution, <B> 15 </B> parts Soda and 2000 parts of water entered. The dye formed precipitates immediately. It is filtered, washed and dried.
