Description
Verfahren zur Gewinnung von fein verteilten trockenen Pigmentfarbstoffen. Es ist bekannt, daß man Pigmentfarbstoffe mit Hilfe einer Reihe von Hilfsmitteln in wäßriger Suspension in äußerst feiner Verteilung gewinnen kann. Bringt man aus dieser wäßrigen Suspension die Pigmente zur Trockne, so geht die feine Verteilung zum größten Teil wieder verlören. Einmal getrocknete Farbstoffe kann man auch selbst mit Hilfe feinster Vermahlung nicht annähernd mehr in den Zustand der Feinheit zurückführen, die sie in der wäßrigen Suspension gehabt haben.Process for the production of finely divided dry pigment dyes. It is known that pigment dyes can be used with the aid of a number of auxiliaries can win in aqueous suspension in extremely fine distribution. One brings out This aqueous suspension brings the pigments to dryness, and so the fine distribution goes mostly lost again. Once dried, you can also use dyes yourself with the help of the finest grinding, do not even come close to returning to the state of fineness, which they have had in the aqueous suspension.
Es wurde nun gefunden, daß man durch innige Vermischung von organischen und anorganischen Pigmenten mit Harzen und höheren (festen) Fettsäuren die feine Verteilung aus der wäßrigen Suspension erhalten und aus einmal getrockneten Pulvern in weitgehendem Maße wiederherstellen kann. Die Ausführung kann beispielsweise in der Weise erfolgen, daß man alkalisch gelöste Harze oder Fettsäuren in der wäßrigen Suspension mit Hilfe von Säuren zur Ausfällung bringt oder auch die Harze und Fettsäuren selbst mit Hilfe von Lösungsmitteln in analoger Weise auf den Pigmenten niederschlägt. Zur Wiederverteilung getrocknet gewesenen Pigmentes, aber auch zur Erhaltung der feinen Verteilung wäßriger Pigmentpaste kann beispielsweise die Schmelze oder auch das Vermahlen in der Kolloidalmiihle Anwendung finden. Das Prinzip des Verfahrens ist, die fein verteilten Pigmente in wäßriger Suspension mit einer Schicht von einer Substanz zu umhüllen, die beim Trocknen die feine Verteilung aufrechterhält und die in organischen Flüssigkeiten löslich ist. Beim Lösen sollen dann die Farbstoffe in der gleichen feinen Verteilung frei gemacht werden, die sie in der ursprünglichen wäßrigen Paste hatten.It has now been found that by intimate mixing of organic and inorganic pigments with resins and higher (solid) fatty acids the fine Distribution obtained from the aqueous suspension and from powders dried once can restore to a large extent. For example, it can be executed in done in the way that one alkaline dissolved resins or fatty acids in the aqueous Brings suspension with the help of acids to precipitate or the resins and fatty acids precipitates on the pigments in an analogous manner even with the aid of solvents. To redistribute dried pigment, but also to preserve the fine distribution of aqueous pigment paste can, for example, the melt or grinding in the colloidal mill can be used. The principle of the procedure is, the finely divided pigments in aqueous suspension with a layer of one To envelop substance that maintains fine distribution when dry and which is soluble in organic liquids. When dissolving, the dyes should then can be made free in the same fine distribution that they were in the original aqueous paste.
Die neuen Präparate können vorteilhaft in allen Fällen Verwendung finden, in welchen die mit ihnen vereinigten Körper nicht störend wirken. Man kann aber auch durch bestimmte Lösungsmittel vor der Verwendung der Farbstoffe die beigemengten Präparate unter Erhaltung der feinen Verteilung aus ihnen wieder herauslösen. Beispiele. i. Eine verdünnte wäßrige Paste des Farbstoffes, beispielsweise des durch Kupplung von diazotiertem m-Nitro-p-toluidin auf Acetessiganilid erhaltenen, welche 2o Gewichtsteile zooprozentigen Farbstoff enthält, wird mit einer alkalischen Lösung von :ao Gewichtsteilen Kolophonium gut verrührt, mit Salzsäure kongosauer gemacht, abfiltriert, neutral gewaschen und getrocknet. An Stelle von Kolophonium kann man alkalische Lösungen von Schellack, Copal, ferner solche von einem alkalilöslichen Kunstharz, beispielsweise einem solchen, (las in bekannter Weise durch Konclensation von Phenolen oder Carbonsäuren mit Aldehyden erhalten wird, sowie Seifen von Fettsäuren verwenden.The new preparations can be used advantageously in all cases find in which the bodies united with them do not have a disturbing effect. One can but also by certain solvents before the use of the dyes the admixed Remove the preparations from them while maintaining the fine distribution. Examples. i. A dilute aqueous paste of the dye, for example that by coupling obtained from diazotized m-nitro-p-toluidine on aceto-aceticanilide, which 20 parts by weight zoop% dye is mixed with an alkaline solution of: ao parts by weight Colophony stirred well, made Congo acidic with hydrochloric acid, filtered off, neutral washed and dried. Instead of rosin one can use alkaline solutions of shellac, copal, and also those of an alkali-soluble synthetic resin, for example one such, (read in a known manner by the condensation of phenols or carboxylic acids with aldehydes, as well as use soaps of fatty acids.
2. Eine -%väßrige Paste des Farbstoffes, welche 2o Gewichtsteile Zooprozentigen Farbstoff enthält, wird unter gutem Rühren mit einer alkoholischen von 2o Gewichtsteilen Kolophonium versetzt. Zur besseren Abscheidung des Harzes kann noch ausgesalzen werden. Dann wird abgesaugt und getrocknet. Auch kann man für Alkohol sinngemäß andere Lösungsmittel, aus welchen die Harze durch Wasser gefällt werden, anwenden. An Stelle von Kolophonium kann man Schellack, Kunstharz, Fettsäuren und andere verwenden.2. A -% aqueous paste of the dye, which 20 parts by weight zoo percent Contains dye, is stirred well with an alcoholic of 2o parts by weight Rosin added. For better separation of the resin you can also salt out will. Then it is suctioned off and dried. You can also apply for alcohol accordingly use other solvents from which the resins are precipitated by water. Instead of rosin, shellac, synthetic resin, fatty acids and others can be used.
3. Zo g des oben angeführten Pigmentes werden vorsichtig mit 9o g Kolophonium verschmolzen. Es entsteht ein gelber, glasartiger Schmelzfluß, der dann gebrauchsfertig ist.3. Zo g of the above pigment are carefully mixed with 90 g Fused rosin. A yellow, glass-like melt flow develops, which then is ready to use.
a. 63 Gewichtsteile einer Mangansuperoxydpaste, «-elche 2o Gewichtsteile MnO, enthält, werden mit einer verdünnten alkalischen Lösung von .Io Gewichtsteilen Kolophonium gut verrührt und dann mit der dem Alkali entsprechenden Menge Salzsäure versetzt, fil= triert, mehrmals gewaschen und getrocknet. Dasselbe Verfahren kann auf andere anorganische Pigmente, wie Ruß, Erdfarben, fein verteilte Metalle usw., angewendet werden. 3. 144 Gewichtsteile ß-N aphthol werden wie üblich mit -Natronlauge gelöst; hierzu kommen 293 Gewichtsteile Kolophonium, ebenfalls alkalisch gelöst.. Dann wird das Ganze mit Essigsäure gefällt, mit der nötigen Menge Natriumacetat versetzt und mit einer in üblicher Weise bereiteten Diazolösung aus 138 Gewichtsteilen p-Nitranilin gekuppelt.a. 63 parts by weight of a manganese peroxide paste containing 2o parts by weight of MnO are mixed well with a dilute alkaline solution of .Io parts by weight of rosin and then mixed with the amount of hydrochloric acid corresponding to the alkali, filtered, washed several times and dried. The same procedure can be applied to other inorganic pigments such as carbon black, earth colors, finely divided metals, etc. 3. 144 parts by weight of ß-naphthol are dissolved as usual with sodium hydroxide solution; add 293 parts by weight of rosin, also dissolved in an alkaline solution. Then the whole thing is precipitated with acetic acid, mixed with the necessary amount of sodium acetate and coupled with a conventionally prepared diazo solution of 138 parts by weight of p-nitroaniline.
C. Eine in üblicher Weise aus 2o Gewichtsteilen Indigo hergestellte Küpe wird mit einer alkalischen Lösung von 4.o Gewichtsteilen Kolophonium versetzt, durch Luft der Farbstoff ausgeblasen, dann bei Gegenwart von N atr iumsulfit mit der auf das Alkali berechneten Menge Mineralsäure gefällt, abfiltriert, getrocknet.C. One made in the usual way from 20 parts by weight of indigo An alkaline solution of 4.o parts by weight of rosin is added to the vat, the dye is blown out by air, then in the presence of sodium sulfite with the amount of mineral acid calculated on the alkali precipitated, filtered off, dried.
7. Eine in üblicher Weise aus 2ö Gewichtsteilen Indigo hergestellte Küpe wird mit der alkalischen Lösung von 4o Gewichtsteilen Kolophonium versetzt. Es wird sofort wie oben gefällt, die Leukoverbindung abfiltriert und getrocknet.7. One prepared in the usual way from 20 parts by weight of indigo The alkaline solution of 40 parts by weight of rosin is added to the vat. It is immediately precipitated as above, the leuco compound is filtered off and dried.
