Description
Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man diazotiertes P Naphthylamin mit 1- (2'- Chlor) - pheriyl- 3 - methyl-5-pyrazolorr kuppelt. Der neue Farb stoff bildet ein gelbes Pulver, das in Wasser unlöslich, in Benzol' oder andern Lösungs mitteln mit gelber Farbe löslich ist. Er er zeugt auf Acetylzellulose, aus wässerigen Suspbnsionen gefärbt, schöne goldgelbe Fär bungen.
Beispiel: 11 Teile 1-(2'-Chlor)-phenyl-3-methyl-5- pyrazolon werden in verdünnter Sodalösung gelöst und mit einer Diazolösung, hergestellt aus 7,1 Teilen P-Naphtylamin, versetzt. Der in gelben Flocken abgeschiedene Farbstoff wird filtriert, gewaschen und getrocknet.
Zum Färben der Acetylzellulose wird er zweckmässig nicht getrocknet, sondern in Form des feuchten Presskuchens in Gregen- wart eines Schutzkolloides, wie zum Beispiel einer Lösung von Sulfitzelluloseablauge, in einer geeigneten Mühle verrieben.
Process for the production of a new dye. It has been found that a new dye is obtained when diazotized P-naphthylamine is coupled with 1- (2'-chloro) - pheriyl-3 - methyl-5-pyrazolorr. The new dye forms a yellow powder which is insoluble in water, soluble in benzene or other solvents with a yellow color. On acetyl cellulose, colored from aqueous suspensions, it produces beautiful golden yellow colorations.
Example: 11 parts of 1- (2'-chloro) -phenyl-3-methyl-5-pyrazolone are dissolved in dilute soda solution and mixed with a diazo solution made from 7.1 parts of p-naphthylamine. The dye deposited in yellow flakes is filtered, washed and dried.
To color the acetyl cellulose, it is not advisable to dry it, but instead grind it in a suitable mill in the form of the moist presscake in a protective colloid such as a solution of sulphite cellulose liquor.
