Description
Terfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen wertvollen Farbstoff erhält, wenn man den o-Oxyazofarbstoff, welcher durch Vereinigen von diazotiertem 5-Nitro-2-amino-l-pheriol mit 2-(4'-Äthoxy)-phenylamirio-5-oxynaphthalin-7- sulfosäure entsteht, mit Chrom abgebenden Mitteln behandelt. Der neue Farbstoff stellt ein dunkles Pulver dar, löst sich in Wasser mit blauer, in 10 o/oiger Natronlauge mit grünstickig blauer Farbe auf.
Er färbt Wolle, Baumwolle und Kunstseide, ausge nommen Acetatseide, in grünstickig blauen Tönen an.
Beispiel: 5,24 Gewichtsteile des Farbstoffes aus diazotiertem 5-Nitro-2-aminophenol und 2- (p - Phenetyl) - amino - 5 - naphthol -7-sulfosäure werden in 500 Teilen Wasser gelöst und mit einer 1,52 Teilen Cr20s entsprechenden Menge Fluorchrom zum Sieden erhitzt.
Wenn die Chromierung beendet ist, scheidet man den Farbstoff mit Kochsalz ab und trocknet bei mässiger Temperatur.
Terfahren for the production of a new azo dye. It has been found that a new valuable dye is obtained by using the o-oxyazo dye which is obtained by combining diazotized 5-nitro-2-amino-1-pheriol with 2- (4'-ethoxy) -phenylamirio-5-oxynaphthalene -7- sulfonic acid is produced, treated with chromium releasing agents. The new dye is a dark powder that dissolves in water with a blue color, and in 10% sodium hydroxide solution with a greenish blue color.
He dyes wool, cotton and artificial silk, with the exception of acetate silk, in greenish blue tones.
Example: 5.24 parts by weight of the dye from diazotized 5-nitro-2-aminophenol and 2- (p-phenetyl) -amino-5-naphthol-7-sulfonic acid are dissolved in 500 parts of water and a corresponding 1.52 parts of Cr20s Amount of fluorochrome heated to the boil.
When the chromation is complete, the dye is separated off with common salt and dried at a moderate temperature.
