Description
Zusatzpatent zum Hauptpatent Nr. <B>183685.</B> Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff erhält, wenn man diazotiertes 1-Amit)o-4-methylphenyl-3-benzylsulfon mit 2,3-Oxynaphthoesäui#eanilid vereinigt. Der so erhaltene Farbstoff bildet ein scharlachrotes, in Wasser unlösliches Pulver. Auf geeigne ten Substraten, wie zum Beispiel Zellulose, hergestellt, färbt er diese in leuchtend schar lachroten Tönen.
<I>Beispiel:</I> <B>26,1</B> Teile 1-Amino-4-methylphenyl-ä- benzylsulfon (das erhalten wird durch Konden sieren der 1-Nitro-4-methylber)zol-3-sulfinsäui-e mit Benzylchlorid und Reduktion des ent standenen Sulfons) werden wie üblich diazo- tiert und in eine Lösung von<B>26,3</B> Teilen 2,3- Oxynaphthoesäureanilid, <B>50</B> Teilen 30'/oigei- Natronlauge,<B>15</B> Teilen Soda und 2<B>000</B> Teilen Wasser eingetragen. Der gebildete Farbstoff fällt sofort aus. Der scharlachrote Nieder schlag wird filtriert und getrocknet.
Additional patent to main patent no. <B> 183685. </B> Process for the production of a new azo dye. It has been found that a new azo dye is obtained when diazotized 1-amite) o-4-methylphenyl-3-benzylsulfone is combined with 2,3-oxynaphthoic acid anilide. The dye obtained in this way forms a scarlet red powder which is insoluble in water. Produced on suitable substrates such as cellulose, he colors them in bright, sharp, laugh-red tones.
<I> Example: </I> <B> 26.1 </B> parts of 1-amino-4-methylphenyl-benzylsulfone (which is obtained by condensing the 1-nitro-4-methylber) zol-3 -sulfinsäui-e with benzyl chloride and reduction of the resulting sulfone) are diazotized as usual and converted into a solution of <B> 26.3 </B> parts of 2,3-oxynaphthoic anilide, <B> 50 </B> parts 30% sodium hydroxide solution, 15 parts soda and 2 000 parts water are added. The dye formed precipitates immediately. The scarlet precipitate is filtered and dried.
