Description
Zusatzpatent zum Hauptpatent Nr. 152881. Verfahren zur Herstellung eines neuen Azofarlostoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, welcher der Formel:
EMI0001.0003
entspricht, wenn man dianotiertes 4-(1' Methyl)-phenoxyacetylamino -2 . 5- dimethoxy- 1-aminobenzol mit dem 2-Methyl-4-methoxy- anilid der 2.3-Oxynaphthoesäure kuppelt.
Der neue Farbstoff bildet ein dunkel violettes Pulver. Auf geeigneten Substraten, wie zum Beispiel pflanzlichen Fasern, herge stellt, färbt er diese in echten violetten Tönen.
<I>Beispiel:</I> 31,6 Teile 4-(1'-Methyl)-phenoxyacetyl- amino-2.5-dimethoxy-l-aminobenzol werden wie üblich dianotiert und in eine Lösung von 30,7 Teilen des 2-Methyl-4-methoxyanilids der 2.3-Oxynaphthoesäure, 100 Teilen 30 o/oiger Natronlauge, 30 Teilen Soda und 2000 Teilen Wasser eingetragen. Der ge bildete Farbstoff fällt sofort aus. Der dunkel violette Niederschlag wird filtriert und ge trocknet.
Additional patent to the main patent No. 152881. Process for the production of a new azo-fleece. It has been found that a new dye is obtained which has the formula:
EMI0001.0003
corresponds if one dianotated 4- (1 'methyl) -phenoxyacetylamino -2. 5- dimethoxy-1-aminobenzene couples with the 2-methyl-4-methoxyanilide of 2,3-oxynaphthoic acid.
The new dye forms a dark purple powder. On suitable substrates, such as vegetable fibers, he dyes them in real purple tones.
<I> Example: </I> 31.6 parts of 4- (1'-methyl) -phenoxyacetylamino-2,5-dimethoxy-1-aminobenzene are dianotized as usual and in a solution of 30.7 parts of 2-methyl -4-methoxyanilide of 2,3-oxynaphthoic acid, 100 parts of 30% sodium hydroxide solution, 30 parts of soda and 2000 parts of water. The dye formed precipitates out immediately. The dark purple precipitate is filtered and dried ge.
