Wie in den Patentschriften 122904 und 126133 gezeigt worden ist, werden bisher unbekannte, ungeheizte Baumwolle direct färbende Azofarbstoffe durch Einwirkung von Diazoverbindungen auf freie Hydroxylgruppen enthaltende Harnstoffe bezw. Thioharnstoffe der Naphtalinreihe erhalten.As has been shown in patents 122904 and 126133, previously unknown, unheated cotton direct coloring azo dyes through the action of diazo compounds on ureas containing free hydroxyl groups respectively. Obtain thioureas of the naphthalene series.
Es hat sich nun weiter ergeben, dafs man zu Azofarbstoffen von ganz ähnlichen Eigenschaften gelangt, wenn man an Stelle der genannten Harnstoffe bezw. Thioharnstoffe die ähnlich constituirte Dioxydinaphtyläthylendiamindisulfosäure, die durch Einwirkung von Aethylenhaloiden auf die 2-Amido-5-naphtol-7-sulfosäure entsteht, mit Diazoverbindungen zu Farbstoffen vereinigt. Die hieraus gebildeten Farbstoffe besitzen die werthvolle Eigenschaft, ungeheizte Baumwolle direct anzufärben, in hohem Mafse ; sie zeichnen sich ebenfalls durch relativ grofse Säureechtheit und schöne, klare Nuance aus.It has now been found that azo dyes with quite similar properties can be obtained if you replace the ureas mentioned BEZW. Thioureas die similarly constituted dioxydinaphthylethylenediamine disulfonic acid, which is produced by the action of Ethylene haloids on the 2-amido-5-naphthol-7-sulfonic acid is formed, with diazo compounds combined to form dyes. The dyes formed from this have the valuable property to dye unheated cotton directly, to a large extent; they are also characterized by relatively high acid fastness and a beautiful, clear shade.
Bei der Herstellung der Farbstoffe verfährt man in der Weise, dafs man 2 Mol. von Diazoverbindungen mit der Dioxydinaphtyläthylendiamindisulfosäure vereinigt; an Stelle der 2 Mol. einer Monodiazoverbindung kann selbstverständlich auch 1 Mol. einer Tetrazoverbindung Verwendung finden.In the preparation of the dyes one proceeds in such a way that 2 moles of Diazo compounds combined with dioxydinaphthylethylenediaminedisulfonic acid; instead of of the 2 moles of a monodiazo compound can of course also 1 mole of a tetrazo compound Find use.
In eine sodaalkalische Lösung von 50,4 kg Dioxydinaphtyläthylendiamindisulfosäure läfst man unter gutem Rühren eine in üblicher Weise aus 21,4 kg p-Toluidin hergestellte Diazolösung zufliefsen. Nach mehrstündigem Rühren ist die Farbstoffbildung beendet. Es wird nun angewärmt, ausgesalzen, geprefst und getrocknet. Der Farbstoff färbt ungeheizte Baumwolle in schwach alkalischem Bade scharlachroth. In a soda-alkaline solution of 50.4 kg Dioxydinaphtyläthylendiamindisulfonic acid runs one prepared in the usual way from 21.4 kg of p-toluidine with thorough stirring Flow in diazo solution. After several hours of stirring, the formation of the dye has ended. It is now warmed up, salted out, pressed and dried. The dye stains unheated Cotton scarlet in a weakly alkaline bath.
30 kg p-Amidoacetanilid werden in üblicher Weise diazotirt und in eine mit überschüssiger Soda versetzte Lösung von 50,4 kg Dioxydinaphtyläthylendiamindisulfosäure einfliefsen gelassen. Die Farbstoffbildung beginnt sofort und ist nach mehrstündigem Rühren beendet. Es wird angewärmt, der Farbstoff ausgesalzen, geprefst und getrocknet. Er färbt ungeheizte Baumwolle in klaren, blaustichig-rothen Tönen an.30 kg of p-amidoacetanilide are diazotized in the usual way and in one with excess Soda-added solution of 50.4 kg of dioxydinaphthylethylenediaminedisulphonic acid flow in calmly. The formation of the dye begins immediately and ends after stirring for several hours. It is warmed up, the dye is salted out, pressed and dried. He dyes unheated ones Cotton in clear, bluish-red tones.
Eine in üblicher Weise aus 18,4 kg Benzidin hergestellte Tetrazodiphenylchloridlösung wird zu einer. mit überschüssiger Soda versetzten Lösung von 50,4 kg Dioxydinaphtylä'thylendiamindisulfosäure allmählich zugegeben. Nach mehrstündigem Rühren wird angewärmt, der gebildete Farbstoff ausgesalzen, geprefst und getrocknet. Er liefert auf ungeheizter Baumwolle ein klares Violett.One in the usual way from 18.4 kg of benzidine produced tetrazodiphenyl chloride solution becomes one. add excess soda Solution of 50.4 kg of dioxydinaphthylenediaminedisulfonic acid gradually admitted. After several hours of stirring, the mixture is warmed up, the dye formed is salted out and pressed and dried. On unheated cotton it produces a clear violet.
In analoger Weise verfährt man bei Benutzung anderer Diazoverbindungen bezw. Tetrazoverbindungen; an Stelle von 2 Mol. Monodiazoverbindung kann man auch 2 Mol.The procedure is analogous when using other diazo compounds BEZW. Tetrazo compounds; instead of 2 mol. Monodiazo compound, 2 mol.
einer Diazoazoverbindung oder eines Zwischenproductes aus einer Tetrazoverbindung und einem Amin, Phenol oder dergl. verwenden.a diazoazo compound or an intermediate of a tetrazo compound and an amine, phenol or the like. Use.
