Description

Verfahren zur Herstellung eines Monoazofarbstoffes Es wurde gefunden, daß man ein-en neuen Farbstoff erhält, wenn man Diazobenzol mit 1-(2'-Chlor)-phenyl-3-methyl-S-pyrazolon kuppelt. Der neue Farbstoff bildet ein gelbes Pulver, das in Wasser unlöslich, in Benzol oder anderen organischen Lösungsmitteln mit gelber Farbe löslich ist. Er erzeugt auf Acetylcellulose, aus wässerigen Suspensionen gefärbt, reine, gelbe Färbungen von hervorragender Schönheit und Echtheit.Process for the preparation of a monoazo dye It has been found that one obtains a new dye if one diazobenzene with 1- (2'-chloro) -phenyl-3-methyl-S-pyrazolone clutch. The new dye forms a yellow powder that is insoluble in water Benzene or other organic solvents with a yellow color is soluble. He produced on acetyl cellulose, colored from aqueous suspensions, pure, yellow colorations of outstanding beauty and authenticity.

Beispiel ii Teile I-(2'-Chlor)-phenyl-3-methY1-5-PY-razolon werden in verdünnter Sodalösung gelöst und mit einer Diazolösung, hergestellt aus 4,6 Teilen Anilin, versetzt. Der in gelben Flocken abgeschiedene Farbstoff wird filtriert, gewaschen und getrocknet. Zum Färben deT Acetylcellulose wird er zweckmäßig nicht getrocknet, sondern in Form des feuchten Preßkucliens in Gegenwart eines Schutzkolloides, wie z. B. einer Lösung von Sulfitcelluloseablauge, in ein-er geeigneten Mühle verrieben.Example ii Parts of I- (2'-chloro) -phenyl-3-methY1-5-PY-razolone Dissolved in dilute soda solution and with a diazo solution made from 4.6 parts Aniline, added. The dye deposited in yellow flakes is filtered, washed and dried. It is not useful for coloring the acetyl cellulose dried, but in the form of the moist Preßkucliens in the presence of a protective colloid, such as B. a solution of sulphite cellulose liquor, triturated in a suitable mill.

Mit der so gewonnenen Paste lassen sich auf Acetatseide grüngelbe Färbungen von sehr guten Echtheitseigenschaften, insbesondere von sehr guter Lichtechtheit, erzeugen.With the paste obtained in this way, green-yellow can be applied to acetate silk Dyeings with very good fastness properties, in particular very good lightfastness, produce.
