Description
Verfahren zur Darstellung eines neuen gelben Wollfarbstoffes. Das vorliegende Patent betrifft ein Ver fahren zur Darstellung eines gelben Woll- farbstoffes und ist dadurch gekennzeichnet, dass man diazotiertes Metanilsäure-hegadeca- noylamid mit 1-(2',5'-Dichlor-4'-sulfophenyl)- 3-methyl-5-pyrazolon kuppelt. sulfophenyl)-3-methyl-5-pyrazolon zufliessen.
Der abgeschiedene Farbstoff wird filtriert, mit verd. Kochsalzlösung gewaschen und ge trocknet. Er stellt ein gelbes Pulver dar und färbt Wolle aus saurem Bade in grünstichig gelben Tönen an, die walk-, schweiss- und lichtecht sind.
Beispiel: 41 Gewichtsteile Metanilsäure-hegadeca- noylamid, erhalten durch Einwirkung von Palmitinsäurechlorid auf 1-Nitrobenzol-3-sul- fonsäureamid und nachfolgende Reduktion,
werden in Eisessig gelöst und nach Zusatz von 25 Gewichtsteilen 30% iger Salzsäure mit 7 Gewichtsteilen Natriumnitrit diazotiert. Die Diazolösung lässt man in die eine aus reichende Menge Soda enthaltende- Lösung von 32,3 Gewichtsteilen 1-(2',5'-Dichlor-4'-
Process for the preparation of a new yellow wool dye. The present patent relates to a process for the preparation of a yellow wool dye and is characterized in that diazotized metanilic acid-hegadecanoylamide with 1- (2 ', 5'-dichloro-4'-sulfophenyl) -3-methyl-5 -pyrazolon couples. sulfophenyl) -3-methyl-5-pyrazolone.
The deposited dye is filtered off, washed with dilute sodium chloride solution and dried. It is a yellow powder and dyes wool from an acid bath in greenish yellow tones that are fast, sweat and lightfast.
Example: 41 parts by weight of metanilic acid hegadecanoylamide, obtained by the action of palmitic acid chloride on 1-nitrobenzene-3-sulphonic acid amide and subsequent reduction,
are dissolved in glacial acetic acid and, after addition of 25 parts by weight of 30% strength hydrochloric acid, diazotized with 7 parts by weight of sodium nitrite. The diazo solution is added to the solution of 32.3 parts by weight of 1- (2 ', 5'-dichloro-4'-
