Description
Verfahren zur Herstellung von Küpenfarbstoffpräparaten Es wurde gefunden, daß man neue Küpenfarbstoffpräparate erhält, wenn man Mischungen, bestehend aus Pasten von Küpenfarbstoffen und Sulfitcelluloseablauge bzw. Ligninsulfonsäuresalzen, mit oder ohne Zusatz von Türkischrotöl o. dgl. zur Trockne eindampft und gegebenenfalls vermahlt.Process for the production of vat dye preparations It has been found that one obtains new vat dye preparations when one mixes consisting of Pastes of vat dyes and sulphite cellulose waste liquor or lignosulphonic acid salts, with or without the addition of Turkish red oil or the like. Evaporated to dryness and if necessary married.
Es werden so Küpenfarbstoffpräparate erhalten, welche in Wasser sofort unter Bildung kolloidaler Lösungen bzw. Suspensionen zerfallen, so daß sie in Gegenwart von Alkalien und Reduktionsmitteln augenblicklich verküpen, was einen großen technischen Fortschritt bedeutet. Die Produkte können direkt zum Färbebade gegeben werden und im Druck ohne Verküpung und nur mit Wasser angeteigt der Druckfarbe beigemischt werden, was z. B. im Hydrosulfitformaldehyddruck einen großen Vorteil bedeutet.In this way vat dye preparations are obtained, which in water immediately disintegrate with the formation of colloidal solutions or suspensions, so that they are in the presence of alkalis and reducing agents instantly vat what a great technical Means progress. The products can be added directly to the dye bath and in the print without vatting and only mixed with water made into a paste with the printing ink become what z. B. in hydrosulfite formaldehyde pressure means a great advantage.
Die erzeugten Drucke stehen in bezug auf Ausgiebigkeit und Gleichmäßigkeit denjenigen, welche mit sorgfältig hergestellten Pasten erzielt werden, nicht nach.The prints produced are related to coverage and evenness does not follow those obtained with carefully made pastes.
Beispiel i ioo Teile Flavanthren (vgl. Schultz, Farbstofftabellen, 6. Auflage, Nr. 849) werden in iooo Teilen konzentrierter Schwefelsäure gelöst, auf Eis ausgetragen, filtriert, mit Wasser bis zum Verschwinden der sauren Reaktion gewaschen, hierauf mit Zoo Teilen einer 5o°/oigen Sulfitcelluloseablauge verrührt, getrocknet und gemahlen. Man bekommt ein Pulver, das sich in Wasser unter Zusatz von Hydrosulfit und Natronlauge sofort löst. Im Baumwolldruck kann der so erhaltene Farbstoff entweder direkt oder nach Anteigen mit wenig Wasser zur Verdickung zugegeben werden. Man bekommt eine Druckfarbe, welche auch in hellen Tönen vollkommen egale Drucke liefert.Example 100 parts of flavanthrene (see Schultz, color tables, 6th edition, No. 849) are dissolved in 1,000 parts of concentrated sulfuric acid, Discharged onto ice, filtered, with water until the acidic reaction disappears washed, then stirred with zoo parts of a 50% sulphite cellulose waste liquor, dried and ground. You get a powder that can be added to water of hydrosulphite and sodium hydroxide solution dissolves immediately. The resulting Dye added either directly or after pasting with a little water for thickening will. You get a printing ink that is perfectly level even in light tones Prints supplies.
Mit den andern Küpenfarbstoffen der Anthrachinonreihe, wie z. B. dem N-Dihydro-i,2,i',2'-anthrachinonazin und seinen Substitutionsprodukten, erhält man ähnliche Resultate.With the other vat dyes of the anthraquinone series, such as. B. the N-dihydro-i, 2, i ', 2'-anthraquinonazine and its substitution products are obtained similar results.
Beispiel 2 ioo Teile Cibaviolett B (vgl. Schultz, Farbstofftabellen, 6. Auflage, Nr. goz) werden wie im vorigen Beispiel behandelt. Man bekommt ein Produkt, das in alkalischer Hydrosulfitlösung augenblicklich verküpt und das im Baumwolldruck, mit wenig Wasser angeteigt, direkt zur Verdickung gegeben werden kann und so eine Druckfarbe liefert, welche hervorragend egale und scharfe Drucke gibt. Ähnliche Resultate erhält man mit den indigoiden Farbstoffen von verschiedensten Konstitutionen, wie Indigo, Indirubin, Thioindigo, Thionaphthenindolindigo, Thionaphthenacenaphthenindigo, deren Derivaten und Substitutionsprodukten. USW. Example 2 100 parts of Cibaviolet B (cf. Schultz, color tables, 6th edition, no. Goz) are treated as in the previous example. The result is a product which instantly vatters in alkaline hydrosulfite solution and which can be added directly to thickening in cotton printing, made into a paste with a little water, and thus provides a printing ink which gives excellent level and sharp prints. Similar results are obtained with indigoid dyes of the most varied of constitutions, such as indigo, indirubin, thioindigo, thionaphthene indoline indigo, thionaphthenacenaphthene indigo, their derivatives and substitution products. ETC.
Beispiel 3 =45 Teile a # 5-Dianilidobenzochinon werden durch Lösen in Schwefelsäure und Austragen in Eiswasser verpastet, hierauf mit 58 Teilen einer 5o°/oigenMonopolseifenlösung (wässerige Lösung eines Alkalisalzes eines Sulforicinats) und 58Teilen einer 5o°/oigen Sulfitcelluloseablauge verrührt, getrocknet und gemahlen. Man erhält ein dunkelbraunes Pulver, das in lauwarmem Wasser unter Zusatz von Natronlauge und Hydrosulfit sofort verküpt. Ähnliche Resultate erhält man mit den Farbstoffen des Patentes 263 382 und dessen Zusätzen oder den Farbstoffen der französischen Patentschrift 588 283.Example 3 = 45 parts of a # 5-dianilidobenzoquinone are dissolved by dissolving pasted in sulfuric acid and discharging into ice water, then with 58 parts of a 50% monopole soap solution (aqueous solution of an alkali salt of a sulforicinate) and 58 parts of a 50% sulfite cellulose waste liquor, stirred, dried and ground. A dark brown powder is obtained which is dissolved in lukewarm water with the addition of sodium hydroxide solution and hydrosulfite immediately vat. Similar results are obtained with the dyes of patent 263 382 and its additives or the dyes of the French Patent 588,283.
