CH,CH,
durch Kombination mit ß-Naphtol einen Farbstoff liefert, der mit Vorteil in der Lackfarbenfabrikation Verwendung finden kann, da er eine leuchtend blaurote Nuance besitzt, unlöslich in Wasser und in Öl ist und sehr gute Lichtechtheit aufweist.in combination with ß-naphthol provides a dye that is advantageous in paint production Can be used because it has a bright blue-red shade, is insoluble in water and in oil and very has good lightfastness.
18,2 kg Nitroaminokresolmethyläther werden in 50 kg Salzsäure von 12° Be. gelöst und unter guter Kühlung vermittels einer wässerigen Lösung von 7 kg Nitrit diazotiert. Die Diazolösung läßt man einfließen in eine wässerige Suspension von fein verteiltem ß-Naphtol, welche man dadurch erhält, daß man 15 kg ß-Naphtol auf Zusatz von 12 kg Natronlauge von 400 Be. in etwa 300 1 Wasser löst und diese Lösung mit verdünnter Essigsäure anNOS 18.2 kg of nitroaminocresol methyl ether are dissolved in 50 kg of hydrochloric acid of 12 ° Be. dissolved and diazotized with good cooling by means of an aqueous solution of 7 kg of nitrite. The diazo solution is allowed to flow into an aqueous suspension of finely divided beta-naphthol, which is obtained by reacting 15 kg ß-naphthol on an extra 12 kg of sodium hydroxide of 40 0 Be. Dissolve in about 300 l of water and add this solution to NOS with dilute acetic acid

säuert. Zur Beendigung der Kombination fügt man dem Gemisch noch 10 kg essigsaures Natron zu, filtriert den ausgeschiedenen Farbstoff und wäscht ihn aus. Der Farbstoff kann entweder in Form einer Paste direkt verwendet oder getrocknet werden.acidifies. To end the combination, 10 kg of acetic acid are added to the mixture Add baking soda, filter the precipitated dye and wash it out. The dye can either used directly in the form of a paste or dried.
Behufs Herstellung von Pigmentfarben kann die eben beschriebene Kupplung der Diazoverbindung mit (3-Naphtol auch bei Gegenwart eines der in der Lackfarbenfabrikation üblichen Substrate, wie z. B. Tonerdehydrat, Schwerspat usw., vorgenommen werden.The coupling of the diazo compound just described can be used for the production of pigment colors with (3-naphthol even in the presence of one of those used in paint production common substrates, such as. B. alumina hydrate, barite, etc., can be made.
