Description
Verfahren zur Herstellung salzartiger Verbindungen von Farbbasen Es wurde gefunden, daß basische Farbstoffe mit Phenolen, Naphtholen, Pyrazolonen und allgemein mit solchen organischen Oxyverbindungen, deren Hydroxylwasserstoff sauren Charakter trägt, neue wohl charakterisierte Verbindungen bilden. Diese neuen Farbsalze können infolge ihrer- Löslichkeit in organischen Mitteln mit besonderem Vorteil zur Herstellung von gefärbten Lacken u. dgl. Anwendung finden.Process for the production of salt-like compounds of color bases Es it was found that basic dyes with phenols, naphthols, pyrazolones and generally with those organic oxy compounds whose hydroxyl hydrogen is acidic Bearing character, forming new, well-characterized connections. These new color salts can be of particular advantage due to their solubility in organic agents for the production of colored lacquers and the like.
Beispiel i 5o Teile Brillantgrün (Schultz , Farbstofftabellen, 5. Aufl. Nr. 499) werden gelöst in iooo Teilen Wasser und nach Erkalten unter gutem Rühren zu einer Lösung von 25 Teilen des Azofarbstoffs aus Diazobenzol und Resorcin in iooo Teilen Wasser und 25 Teilen konzentrierter Natronlauge gegeben. Das neue Salz fällt als moosgrüner Körper aus.Example i 50 parts of brilliant green (Schultz, Dyestuff Tables, 5th edition. No. 499) are dissolved in 1,000 parts of water and, after cooling, with thorough stirring to form a solution of 25 parts of the azo dye composed of diazobenzene and resorcinol in 1,000 parts of water and 25 parts of concentrated Given caustic soda. The new salt precipitates out as a moss-green body.
Beispiel 2 _3o Teile salzsaures Methylenblau (Schultz, a. a. O. Nr. 659), in i ooo Teilen Wasser gelöst, werden bei q.0° unter Rühren zu einer alkalischen Lösung von a-Nitroso-3-Naphthol gegeben. Das ausgefallene Nitrosonaphtholmethylenblau wird abgesaugt,- gewaschen und getrocknet.Example 2 _3o parts of hydrochloric acid methylene blue (Schultz, op. Cit. No. 659), dissolved in 1,000 parts of water, become alkaline at 0 ° with stirring Solution of a-nitroso-3-naphthol given. The failed nitrosonaphthol methylene blue is sucked off, washed and dried.
Beispiel 3 32,5 Teile Fuchsin (Schultz, a. a. O. Nr. 5i2) in iooo bis i5oo Teilen Wasser werden zu einer filtrierten Lösung von 3o Teilen 3-Naphth.ol und 25 Teilen Natronlauge von 33 0'O in iooo Teilen Wasser gegeben bei: 30°. Erhalten werden 445 Teile eines braunroten kristallisierten Produktes.Example 3 32.5 parts of fuchsin (Schultz, loc. Cit. No. 5i2) in 1,000 to 1,500 parts of water are added to a filtered solution of 3o parts of 3-naphthol and 25 parts of 33.0% sodium hydroxide solution in 1,000 parts of water at: 30 °. 445 parts of a brown-red crystallized product are obtained.
Beispiel q.Example q.
.1.o,5 Teile Kristallviolett (Schultz, a.a.0. Nr.516), in iooo Teilen Wasser gelöst, werden unter Rühren zu einer Lösung von 2o Teilen o-Nitrophenolnatrium in iooo Teile Wasser gegossen. Der anfangs harzartige Niederschlag wird bei längerem Rühren fest. Nach dem Abfiltrieren von der Flüssigkeit und Trocknen erhält man 46 Teile grünglänzendes Pulver. Beispiel 5 q.o Teile Methylviolett (S c h u 1 t z , a. a. O. Nr. 515) werden in r ooo Teilen Wasser heiß gelöst und nach Filtrieren und ° Erkalten zu einer Lösung von -o Teilen Phenylinethyl.-pyrazolonzn 13 Teilen Natronlauge von 33 0,10 in iooo Teilen Wasser gegeben und einige Stunden gerührt. Die Aufarbeitung ergibt ein bronzefarbenes Salz..1.o, 5 parts of crystal violet (Schultz, op. The initially resinous precipitate solidifies after prolonged stirring. After filtering off the liquid and drying, 46 parts of a green, glossy powder are obtained. Example 5 qo parts of methyl violet (S chu 1 tz, loc. Cit. No. 515) are dissolved in r ooo parts of hot water and, after filtering and cooling, 13 parts of sodium hydroxide solution of 33 % to give a solution of -o parts of phenylinethyl-pyrazolone. 10 given in iooo parts of water and stirred for a few hours. The work-up results in a bronze-colored salt.
