Description
Zusatzpatent zum Hauptpatent Nr. 3'108i30 Verfahren zur Herstellung eines wasserunlöslichen Disazofarbstoffes Gegenstand des vorliegenden Zusatzpaten tes ist ein Verfahren zur Herstellung eines wasserunlöslichen Disazofarbstoffes, welches dadurch gekennzeichnet ist, dass man die Tetrazoverbindung von 4,4' - Diamino-3,3'-di- chlordiphenyj mit 1- Acetoaeetylamino,2=äth- oxybenzol kuppelt.
Beispiel 50,6 Clewiclitsteile 4,4'-Diamino -<B>2,3'-</B> di- clilordiphenyl werden mit 600 Volumteilen Wasser und 270 VolLimteilen 5n-Salzsäure verrührt, dann mit Eis auf @0 C gekühlt und mit 5'2:
,5 Volumteilen 40prozentiger Na trittmnitritlösLmg bei 0 C tetrazotiert. Die ge- hlärte Tetrazolösung wird unter gutem Rüh ren. bei 20 C zu einer essigsauren Suspension @-on <B>92</B> Gewichtsteilen 1-Aeetoacetylamino 2- iitlioxybenzol gegeben.
Nach beendeter Kupp lung wird der Farbstoff bei gewöhnlicher Temperatur filtriert, neutral gewaschen und getrocknet, Die Kopplung kann mit Vorteil auch in Gegenwart von Harzseife durchge führt werden.
Das so erhaltene Produkt ist ein farb- kräftiges grünstichig gelbes Pulver mit guten Echtheitseigenschaften, das zum Färben von Kunststoffen und für den graphischen Druck sowie für spezielle Gebiete der Lack-, Tapeten- und Papierindustrie verwendet werden kann.
Additional patent to the main patent No. 3'108i30 Process for the production of a water-insoluble disazo dye The subject of the present additional patent is a process for the production of a water-insoluble disazo dye, which is characterized in that the tetrazo compound of 4,4'-diamino-3,3'- dichlordiphenyj with 1-acetoaeetylamino, 2 = ethoxybenzene couples.
EXAMPLE 50.6 parts by volume of 4,4'-diamino - 2,3 '- dichlorodiphenyl are stirred with 600 parts by volume of water and 270 parts by volume of 5N hydrochloric acid, then cooled to @ 0 C with ice and mixed with 5'2:
, 5 parts by volume of 40% Na is tetrazotized at 0 C. The hardened tetrazo solution is added with thorough stirring. At 20 ° C. to an acetic acid suspension @ -on 92 parts by weight of 1-aetoacetylamino-2-iitlioxybenzene.
After coupling is complete, the dye is filtered at normal temperature, washed neutral and dried. Coupling can also be carried out with advantage in the presence of resin soap.
The product obtained in this way is a strongly colored greenish yellow powder with good fastness properties, which can be used for coloring plastics and for graphic printing as well as for special areas of the paint, wallpaper and paper industry.
