KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es hat sich gezeigt, dafs die Ct1 ß4-Dioxyßj-naphtoe'-a2-sulfosäure des Patentes Nr. 84653 sich mit den Tetrazoverbindungen des Dianisidins und Tolidins zu Farbstoffen combiniren läfst, deren werthvolle Eigenschaften analoge bezw. isomere Farbstoffe nicht aufweisen.It has been shown that the Ct 1 ß 4 -Dioxyßj-naphtoe'-a 2 -sulfonic acid of Patent No. 84653 can be combined with the tetrazo compounds of dianisidine and tolidine to form dyes whose valuable properties are analogous or similar. do not have isomeric dyes.
Diese Eigenschaften treten gegenüber den Farbstoffen des Patentes Nr. 75258 (aus der Nigrotinsäure) einerseits dadurch hervor, dafs sie in der Baumwollfärberei unerreichte Nuancen bezüglich Grünstichigkeit und Reinheit erzeugen; aufserdem ist ein besonderer, technisch wichtiger Erfolg darin zu erblicken, dafs die Farbstoffe zur Verwendung in der Halbwollfä'rberei besonders geeignet sind. Während nämlich die Farbstoffe des Patentes Nr. 75258 Halbwolle nur in schwachen und mifsfarbigen Tönen anfärben und somit für die Halbwollfä'rberei unbrauchbar sind, erzeugen die vorliegenden auf der gemischten Faser lebhafte und satte blaue Nuancen.These properties appear compared to the dyes of patent no.75258 (from the Nigrotinic acid), on the one hand, by the fact that it has nuances which are unmatched in cotton dyeing generate greenish tint and purity; there is also a special one that is technically important Success in seeing that the dyes for use in semi-wool dyeing are especially important are suitable. Namely, while the dyes of patent no. 75258 half wool Dye only in weak and mifs-colored shades and therefore suitable for dyeing of semi-wool are useless, the present ones produce vivid and rich on the mixed fiber blue nuances.
Beispiel 1.Example 1.
24 kg Dianisidinbase werden wie üblich in die Tetrazoverbindung übergeführt und in eine sodaalkalische Lösung von 70 kg dioxynaphtoesulfosaurem Natron bei ca. 30 ° einlaufen gelassen. Zunächst bildet sich ein Zwischenproduct, welches in alkalischer Lösung löslich ist, auf Zusatz von Säuren aber ausfällt. Den bis zur Vollendung der Farbstoffbildung alkalisch gehaltenen Ansatz läfst man 24 Stunden stehen, erwärmt auf ca. 8o° und läfst erkalten. Bei genügender Concentration des Ansatzes scheidet sich der Farbstoff in grünlichen Krystallen aus, welche sich in Wasser und concentrirter Schwefelsäure mit grünblauer Farbe lösen. Er färbt Baumwolle und Halbwolle grünstichig blau. Die Färbungen sind alkaliecht, Sodalösung (1:10) bringt sowohl auf den Ausfärbungen als auch in den wässerigen Lösungen keine Veränderung hervor.24 kg of dianisidine base are converted into the tetrazo compound as usual and into a soda-alkaline solution of 70 kg of dioxynaphthoesulfonate of soda was allowed to run in at approx. 30 °. First, an intermediate product is formed which is soluble in an alkaline solution, but precipitates when acids are added. The The batch, which is kept alkaline until the formation of the dye is complete, is allowed to run for 24 hours stand, heated to approx. 80 ° and let cool down. With sufficient concentration of the approach the dye is deposited in greenish crystals, which are in water and dissolve concentrated sulfuric acid with a green-blue color. He dyes cotton and semi-wool greenish blue. The colors are alkaline, soda solution (1:10) brings both no change emerged on the colorations or in the aqueous solutions.
Bei analogem Arbeiten wie im gegebenen Beispiel kann man das Dianisidin durch äquivalente Mengen (21 kg) Tolidin ersetzen und erhält so einen Farbstoff, der ungeheizte Baumwolle blau färbt. Die Färbungen sind sodaecht. Der Farbstoff stellt ein bronzeglänzendes Pulver dar. Wasser und concentrirte Schwefelsäure lösen ihn mit blauer Farbe.When working analogously to the example given, the dianisidine can be replaced by equivalents Substitute quantities (21 kg) of tolidine and thus obtain a dye, the unheated cotton colors blue. The colors are so fast. The dye provides a bronze sheen Powder. Water and concentrated sulfuric acid dissolve it with a blue color.
Anstatt in den beiden Beispielen von vornherein 2 Mol. der Säure zu verwenden, kann man auch erst das Zwischenproduct darstellen und dann das zweite Molecül der Säure zugeben. Instead of using 2 mol of the acid from the outset in the two examples, can the intermediate product can also be presented first and then the second molecule of the acid is added.
In umstehender Tabelle ist die Verschiedenheit der Färbungen zusammengestellt, welche mittelst der analogen Farbstoffe aus den beiden bis jetzt bekannt gewordenen Dioxynaphtoesulfosäuren erzielt werden:The table below shows the differences in coloration, which mean of the analogous dyes from the two dioxynaphthoesulfonic acids that have become known up to now be achieved:
