Description
Patentiert im Deutschen Reiche vom 15. April 1906 ab.Patented in the German Empire on April 15, 1906.
Von den vielen Azofarbstoffen, welche sich für die Herstellung roter Farblacke eignen, kommen· für die Erzielung stark blaustichig roter Nuancen von großer Reinheit des Tons und guten Echtheitseigenschaften nur sehr wenige Farbstoffe in Betracht, zumal wenn auch den übrigen Anforderungen der Lackfarbenindustrie genügend Rechnung getragen werden soll.Of the many azo dyes that are are suitable for the production of red colored lacquers, come · to achieve a strong bluish cast red nuances of great purity of the tone and good fastness properties only very few dyes in consideration, especially if the other requirements of the paint industry sufficient account should be taken.
ίο Es wurde nun gefunden, daß der Monoazofarbstoff aus |3-Oxynaphthoesäure-2 · 3 (Schmelzpunkt 2i6°) mit 2-Diazonaphthalin-i-sulfosäure Farblacke von ganz besonderem Wert liefert. Diese Lacke zeigen nämlich große Farbkraft und einen Blaustich der Nuance, wie es bisher nur mit dem Farbstoff der Patentschrift 163644 in annähernder Reinheit erhalten werden konnte. Indessen zeichnen sich die Farblacke aus dem nach vorliegendem Verfahren erhältlichen Farbstoff vor demjenigen dieses bekannten Farbstoffs durch ihre erheblich höhere Lichtechtheit aus. Der um die Carboxylgruppe ärmere Farbstoff aus 2-Diazonaphthalini-sulfosäure und ß-Naphthol der Patentschrift 112833 liefert weit gelbstichigere Lacke, die, wenn es sich um die Herstellung von blauroten Bordeauxnuancen handelt, nicht in Betracht kommen können. Die Lacke eignen sich' vorzüglich zur Verwendung im Buch-, Stein- und Blechdruck sowie für ölanstriche. Die Darstellung des neuen Farbstoffs geschieht z. B. wie folgt:ίο It has now been found that the monoazo dye from | 3-oxynaphthoic acid-2 · 3 (melting point 26 °) with 2-diazonaphthalene-i-sulfonic acid Provides colored lacquers of very special value. This is because these paints show great color strength and a bluish tint of the shade, as was previously only possible with the dye of the patent specification 163644 could be obtained in approximate purity. Meanwhile, the colored lakes stand out from the dye obtainable by the present process before that of this known dye due to their significantly higher lightfastness. The one around the carboxyl group poorer dye made from 2-diazonaphthalenesulfonic acid and ß-naphthol of patent specification 112833 provides varnishes with a far more yellowish tinge, which, when it comes to the production of blue-red burgundy nuances, not considered can come. The varnishes are ideal for use in books, Stone and metal printing as well as for oil painting. The new dye is displayed z. B. as follows:
Man löst 24,5 Teile 2-naphthylamin-i-sulfosaures Natron nebst wenig mehr als der äquivalenten Menge Natriumnitrit in der nötigen Menge Wasser und läßt die kalt gehaltene Lösung in kalte verdünnte Salzsäure einfließen, welche etwas mehr als 2 Äquivalente Chlorwasserstoff enthält, so daß nach beendeter Diazotierung noch Säureüberschuß vorhanden und salpetrige Säure deutlich nachweisbar ist. Die so erhaltene Diazolösung läßt man langsam in eine mit der nötigen Menge Wasser hergestellte Lösung von 20 Teilen ß-Oxynaphthoesäure-2 · 3 (Schmelzpunkt 216c) nebst 25 Teilen Natronlauge von 40 ° Be. und etwa 6 Teilen calcinierter Soda einlaufen. Die Farbstoffbildung ist in kurzer Zeit beendet. Der rote Farbstoff, welcher meist völlig abgeschieden ist, wird auf die übliche Weise isoliert und zweckmäßig in Pastenform für die Farblackbereitung angewendet; er kann jedoch auch, da seine Wasserlöslichkeit eine genügende ist, in Pulverform hergestellt und verwendet werden.24.5 parts of 2-naphthylamine-i-sulfonic acid sodium and a little more than the equivalent amount of sodium nitrite are dissolved in the necessary amount of water and the solution, which is kept cold, is poured into cold dilute hydrochloric acid, which contains a little more than 2 equivalents of hydrogen chloride, so that after the end of the diazotization, excess acid is still present and nitrous acid is clearly detectable. The diazo solution obtained in this way is slowly poured into a solution of 20 parts of β-oxynaphthoic acid 2 · 3 (melting point 216 c ) and 25 parts of sodium hydroxide solution at 40 ° Be, prepared with the necessary amount of water. and pour in about 6 parts of soda ash. The dye formation is complete in a short time. The red dye, which is usually completely separated, is isolated in the usual way and used appropriately in paste form for the preparation of colored lacquers; however, since its water solubility is sufficient, it can also be prepared and used in powder form.
