PATENTAMT.PATENT OFFICE.
Die 2>3-Oxynaphtoesäure hat bis jetzt keine
technische Verwendung gefunden. Es wurde nun die Beobachtung gemacht, daß sie sich
mit den Diazoverbindungen folgender Amidobenzolsul f osäuren:
X The 2> 3-oxynaphtoic acid has so far not found any industrial use. The observation has now been made that they become acidic with the diazo compounds of the following amidobenzene sulfo:
X
S0„H,S0 "H,
NH0 NH 0
wobei X CH9, C2H0, N O2, Cl, Br, O Alk. bedeutet, zu Monoazofarbstoffen vereinigen läßt, die zur Darstellung roter Farblacke hervorragend geeignet sind. Die Natriumsalze der genannten Farbstoffe, die in kaltem Wasser schwer löslich sind, lassen sich leicht in die entsprechenden Calcium-, Baryum-, Aluminium-, Zink- und andere Salze überführen, die durch vollständige Unlöslichkeit in Wasser und Öl und durch große Lichtechtheit aus-' gezeichnet sind.where X is CH 9 , C 2 H 0 , N O 2 , Cl, Br, O Alk. , can be combined to form monoazo dyes, which are outstandingly suitable for the production of red colored lakes. The sodium salts of the dyes mentioned, which are sparingly soluble in cold water, can easily be converted into the corresponding calcium, barium, aluminum, zinc and other salts, which are characterized by their complete insolubility in water and oil and their high lightfastness. 'are drawn.
Die nach dem vorliegenden Verfahren dargestellten Farbstoffe geben Farblacke, welche sich vor denen, die aus den Farbstoffen der Patentschriften 128456 und 135842 erhalten werden können, durch eine viel tiefere und mehr blaustichigrote Nuance auszeichnen; infolge dieser Eigenschaften sind die nach dem vorliegenden Verfahren dargestellten Farbstoffe für die Farblackfabrikation ganz besonders geeignet und ihre Herstellung bedeutet daher einen gewerblichen Fortschritt.The dyes prepared by the present process give color lakes, which ahead of those obtained from the dyes of patents 128456 and 135842 can be characterized by a much deeper and more bluish-red shade; as a result of these properties are the dyes produced by the present process particularly suitable for color lacquer production and its production means hence an industrial advance.
18,7 Teile p-Toluidinsulfosäure (s. obige Formel) wurden nach bekannter Methode diazotiert und die ausgeschiedene Diazovcrbindung in eine kalte, sodaalkalische Lösung von 18,8 Teilen 2 · 3-Oxynaphtoesäure eingetragen, wobei die Reaktionsflüssigkeit beständig alkalisch zu halten ist. Die Kombination geht fast augenblicklich vonstatten. Nachdem man auf etwa 8o° angewärmt hat, wird etwas Kochsalz hinzugefügt, filtriert und mit Wasser gewaschen. Der Farbstoff findet zweckmäßig als Paste Verwendung; in trockenem Zustande bildet er ein rotes, metallisch glänzendes Pulver.18.7 parts of p-toluidine sulfonic acid (see above Formula) were diazotized by a known method and the diazo bond separated out added to a cold, soda-alkaline solution of 18.8 parts of 2 3-oxynaphthoic acid, the reaction liquid is to be kept constantly alkaline. The combination happens almost instantly. After it has been warmed to about 80 °, a little table salt is added and filtered and washed with water. The dye is expediently used as a paste; in when dry it forms a red powder with a metallic sheen.
