Verfahren zur Darstellung von o-Oxyazofarbstoffen.
EMI1.1
bau Naphtalin-1.2-diazoxyd-4-sulfosäuren verwendet, welche in 6- oder 7-Stellung eine Aeidyloxygruppe enthalten. Die Anwesenheit dieser Gruppe verbessert die Echtheitseigenschaften.
Die für dieses Verfahren benötigten Diazoxyde gewinnt man, indem man 1-Amino-2. 6- bzw.
EMI1.2
Beispiel 1. 9 Teile 4-Toluolsulfosäureester der 7-0xynaphtalin 1. 2-diazoxyd-4-sulfosäure werden, in 270 Teilen Wasser gelöst, zu einer Lösung von 3-5 Teilen 1-Phenyl-3-metyl-5-pyrazolon, 1 Teil Natriumhydroxyd und 2 Teilen wasserfreiem Natriumkarbonat in 140 Teilen Wasser bei 5-10'gegeben. Die Bildung des Farbstoffs ist nach kurzer Zeit beendet. Er wird in der üblichen Weise aufgearbeitet. Auf Wolle färbt er ein stumpfes Orange, das durch Chromieren in ein stumpfes blaustichiges Rot übergeht. Auch in Gegenwart von neutralen Chromaten und dissozierenden Ammonsalzen lässt er sich färben.
Die Färbungen sind wasch-und walkechter als die mit dem aus Naphtalin-1. 2-diazoxyd-4-sulfosäure und 1-Phenyl-3-methyl-5-pyrazolon dargestellten Farbstoff des deutschen Patents Nr. 165743 erzeugten.
EMI1.3
Beispiel 4.8 Teile Benzoesäureester der 7-0xynaphtalin-1. 2-diazoxyd-4-sulfosäure werden, in 240 Teilen Wasser gelöst, zu einer Lösung von 3'5 Teilen 1-Phenyl-3-methyl-5-pyrazolon, 1 Teil Natriumhydroxyd und 2 Teilen wasserfreiem Natriumkarbonat in 140 Teilen Wasser bei 5-10'gegeben. Der nach kurzer Zeit gebildete und in üblicher Weise aufgearbeitete Farbstoff färbt auf Wolle ein stumpfes Braun, das beim Nachchromieren in ein bläuliches Rot übergeht.

Process for the preparation of o-oxyazo dyes.
EMI1.1
bau naphthalene-1,2-diazoxyd-4-sulfonic acids are used, which contain an aeidyloxy group in the 6- or 7-position. The presence of this group improves the fastness properties.
The diazoxides required for this process are obtained by adding 1-amino-2. 6- or
EMI1.2
Example 1. 9 parts of 4-toluenesulfonic acid ester of 7-oxynaphthalene 1. 2-diazoxyd-4-sulfonic acid are dissolved in 270 parts of water to form a solution of 3-5 parts of 1-phenyl-3-methyl-5-pyrazolone, 1 Part of sodium hydroxide and 2 parts of anhydrous sodium carbonate in 140 parts of water at 5-10 '. The formation of the dye ends after a short time. It is processed in the usual way. He dyes a dull orange on wool, which turns into a dull bluish red through chroming. It can also be colored in the presence of neutral chromates and dissociating ammonium salts.
The dyeings are more washable and millfast than those made from naphthalene-1. 2-diazoxyd-4-sulfonic acid and 1-phenyl-3-methyl-5-pyrazolone prepared dye of German Patent No. 165743.
EMI1.3
Example 4.8 parts of benzoic acid ester of 7-0xynaphtalin-1. 2-diazoxyd-4-sulfonic acid, dissolved in 240 parts of water, to a solution of 3'5 parts of 1-phenyl-3-methyl-5-pyrazolone, 1 part of sodium hydroxide and 2 parts of anhydrous sodium carbonate in 140 parts of water at 5- 10 'given. The dye, which is formed after a short time and is worked up in the usual way, turns wool a dull brown, which turns into a bluish red when chromium plating.
