Description

Verfahren zur Darstellung von blauen Küpenfarbstoffen Der nach dem Verfahren der Patentschrift 216 891 erhältliche Farbstoff vom Charakter einer N-Dihydro-i - 2 -:2'- i'-anthrachinonazinsulfosäure sowie die aus dieser Verbindung durch Behandlung mit oxydierend wirkenden Mitteln in schwefelsaurer Lösung und darauffolgende Reduktion erhältliche, chlorechtere Färbungen liefernde N-Dihydro-1 - 2 - 2'- i'-anthrachinonazinsulfosäure, ferner die mit dem letztgenannten Produkt praktisch identische, durch Einwirkung milde sulfierend wirkender Mittel, zweckmäßig in Gegenwart von Borsäure, auf reines N-Dihydro-1 -:2 -:2'- i'-anthrachinonazin erhältliche Verbindung liefern auf Baumwolle aus der Küpe Färbungen von wertvoller Nuance, aber mäßiger Farbtiefe.Process for the preparation of blue vat dyes The after Process of the patent specification 216 891 obtainable dye of the character of an N-dihydro-i - 2 -: 2'- i'-anthraquinonazine sulfonic acid and those from this compound by treatment with oxidizing agents in sulfuric acid solution and subsequent reduction available N-dihydro-1 - 2 - 2'-i'-anthraquinonazine sulfonic acid which produces more chlorine-fast coloring, furthermore that which is practically identical to the last-named product, by action mild sulphurizing agents, expediently in the presence of boric acid, on pure N-dihydro-1 -: 2 -: 2'- i'-anthraquinone azine deliver on cotton from the vat colorings of valuable nuance, but moderate depth of color.

Es wurde nun gefunden, daß man wertvolle blaue Küpenfarbstoffe erhält, die in Färberei und Druck außerordentlich wertvolle Eigenschaften, insbesondere wertvollen Farbton, gute Lichtechtheit und gute Ausgiebigkeit, zeigen. wenn man die- nach den obererwähnten Verfahren erhältlichen Farbstoffe mit N-Dihydro-i - 2 - 2' - i'-anthrachinonazin oder dessen Substitutionsprodukten mischt. Das N-Dihydro-i - 2 - 2'- i'-anthrachinonazin und seine Substitutionsprodukte wendet man am besten in einer möglichst reinen, z. B. der nach Patent 421 2o6 erhältlichen Form an, da diese Produkte in reiner Form besonders gute Echtheitseigenschaften aufweisen, was auch in den Eigenschaften der beschriebenen Mischungen vorteilhaft zum Ausdruck kommt. Beispiel i Man mischt 5f,5 Teile des nach Beispiel 4 der Patentschrift 421 2o6 erhältlichen chlorechten N-Dihydro-i - 2 - 2' - i'-anthrachinonazins mit der aus 42,5 Teilen des gleichen Farbstoffes durch Einwirkung von starker Schwefelsäure in Gegenwart von Borsäure erhältlichen Sulfosäure oder der entsprechenden Menge des durch Behandeln der nach dem Verfahren der Patentschrift 216 891 erhältlichen Sulfosäure des ZT-Dihydroi - 2 - 2'- i'-anthrachinonazins mit oxydierend wirkenden Mitteln in schwefelsaurer Lösung entstehenden Farbstoffes. Diese Mischungen liefern aus der warmen Hydrosulfitküpe auf Baumwolle Töne von wertvoller Nuance und vorzüglichen Echtheitseigenschaften. Beispiel e Man mischt 8j,5 Teile reines Monochlor-N-dihydro-i - 2 - 2'. i'-anthrachinonazin, erhältlich z. B. durch Einwirkung von Salzsäure auf reines N-Dihydro-i - 2 - 2' - i'-anthrachinonazin in Gegenwart von wasserhaltiger Schwefelsäure, mit i2,5 Teilen der in Beispiel i verwendeten Sulfosäure. Eine Färbung dieser Mischung aus der warmen Hydrosulfitküpe auf Baumwolle entspricht etwa der nach Beispiel i erhaltenen Färbung, übertrifft diese jedoch an Chlorechtheit und Seifenechtheit.It has now been found that valuable blue vat dyes are obtained which are extremely valuable properties in dyeing and printing, in particular valuable color, good lightfastness and good coverage. if the dyes obtainable by the above-mentioned process with N-dihydro-i - 2 - 2 '- i'-anthraquinone azine or its substitution products. The N-dihydro-i - 2 - 2'- i'-anthraquinonazine and its substitution products are best used in a pure as possible, z. B. the form available according to patent 421 2o6, there these products have particularly good fastness properties in their pure form, what also advantageously expressed in the properties of the mixtures described comes. Example i Mix 5f.5 parts of the mixture according to Example 4 of Patent 421 2o6 available chlorine-resistant N-dihydro-i - 2 - 2 '- i'-anthraquinone azines with the from 42.5 parts of the same dye by the action of strong sulfuric acid sulfonic acid obtainable in the presence of boric acid or the corresponding amount obtained by treating those obtained by the method of patent specification 216,891 Sulphonic acid of the ZT-Dihydroi - 2 - 2'- i'-anthraquinone azines with an oxidizing effect Means in sulfuric acid solution resulting dye. These mixes deliver from the warm hydrosulfite vat on cotton tones of valuable nuances and excellent Authenticity properties. Example e Mix 8.5 parts of pure monochloro-N-dihydro-i - 2 - 2 '. i'-anthraquinonazine, available e.g. B. by the action of hydrochloric acid pure N-dihydro-i - 2 - 2 '- i'-anthraquinonazine in the presence of water-containing Sulfuric acid, with i2.5 parts of the sulfonic acid used in example i. A coloring this mix of the warm Equivalent to hydrosulfite vat on cotton about the coloration obtained according to Example i, but surpasses this in terms of chlorine fastness and soap fastness.
