Description
Zusatzpatent zum Hauptpatent Nr, 161841. Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff der Formel:
EMI0001.0005
erhält, wenn man den 2-Diazo-4.4'-dimeth- oxy-5-acetylamirio-1.1'-diphetiyläther mit dem p-Anisidid der 2. 3-Oxy )aphtoesäure kuppelt.
Der so erhaltene Farbstoff bildet ein rot violettes Pulver. Auf geeigneten Substraten, wie zum Beispiel Baumwolle, Wolle, Kunst seide, hergestellt, färbt er diese in leuchten den, sehr echten violetten Tönen. <I>Beispiel:</I> 30,2 Teile 2-Amino-4.4'-dirnethoxy-5-aee- tylamino-1.1'-diphenyläther werden wie üblich diazotiert und in eine Lösung von 29,3 Teilen des p-Anisidids der 2. 3-Oxynaphtoe- säure, 60 Teilen 30 o/oiger Natriumhydroxyd- lösung, 15 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. 161841. Process for the production of a new azo dye. It has been found that you can create a new azo dye of the formula:
EMI0001.0005
obtained when the 2-diazo-4.4'-dimethoxy-5-acetylamirio-1.1'-diphetiyl ether is coupled with the p-anisidide of the 2. 3-oxy) aphtoic acid.
The dye thus obtained forms a red-violet powder. Produced on suitable substrates such as cotton, wool, artificial silk, he dyes them in bright, very real purple tones. <I> Example: </I> 30.2 parts of 2-amino-4.4'-dirnethoxy-5-aetylamino-1.1'-diphenyl ether are diazotized as usual and converted into a solution of 29.3 parts of the p-anisidide 2. Entered 3-oxynaphthoic acid, 60 parts of 30% sodium hydroxide solution, 15 parts of soda and 2000 parts of water.
The dye formed precipitates immediately. It is filtered, washed and dried.
