Demgremäss führt. man die Chromierung zweck- mässig mit solchen chromabgebenden Mitteln und nach solchen Methoden durch, welche er fahrungsgemäss komplexe Chromverbindungen dieser Zusammensetzung liefern.
Es empfiehlt sich im allgemeinen, auf ein Molekül eines Farbstoffes weniger als ein, mindestens aber ein halbes Atom Chrom zu verwenden und/ oder die Chromierung in schwach saurem bis alkalischem Medium auszuführen. Demzufolge sind auch diejenigen Chromverbindungen, die in alkalischem Medium beständig sind, für die Durchführung des Verfahrens besonders g (Y ut geeignet, wie z. B. solche Chromverbin dungen aliphatiseher Oxycarbonsäuren oder vorzugsweise aromatischer o-Oxycarbonsäuren, welche das Chrom in komplexer Bindung ent halten.
Die Metallisierung geschieht mit Vor teil in der Wärme, offen oder unter Druck, z. B. bei Siedetemperatur des Reaktionsgemi sches, gegebenenfalls in Anwesenheit geeigne ter Zusätze, z. B. in Anwesenheit von Salzen organischer Säuren, von Basen, organischen Lösungsmitteln oder weiteren die Komplex bildung fördernden Mitteln.
Beispiel: 7.3,9 Teile 4-Methoxy-2-amino-l-oxybenzol werden in üblicher Weise in Gegenwart von 18 Teilen 30 /oiger Salzsäure mit 7 Teilen Natriumnitrit diazotiert. Die erhaltene .Sus- f)ension der Diazoverbindimg wird unter gutem Rühren zu einer auf 10 gekühlten Lösung von 29 Teilen 8-Chlor-l-oxy-naphtha- lin-5-sulfonsäuremethylamid,
12 Teilen Na- triumhy dr oxy d und 60 Teilen Pyridin in 200 Teilen )\'asser zufliessen gelassen. Nach be endigter Kupplung wird das Reaktionsgemisch mit 600 Teilen Wasser verdünnt und der ent standene Farbstoff nach Zugabe von 23 Tei len 30oloiger Salzsäure abfiltriert und mit Wasser nachgewaschen. Der Farbstoff wird, vorteilhaft ohne vorherige Trocknung, in die komplexe Chromverbindung übergeführt.
Zu diesem Zweck wird die nach obigen Angaben erhaltene Parbstoffpaste mit 700 Teilen hei ssem Nasser verrührt. Nach Zusatz von 9 Tei len Natriumhydroxy d und 100 Teilen einer Lösung von cliromsalieylsaurem Natrium mit einem Chromgehalt von 2,6 % erhitzt man das Reaktionsgemisch während 4 Stunden unter Rüekfluss zum Kochen.
Man filtriert gegebe nenfalls von ungelösten Verunreinigungen ab und scheidet aus dem Filtrat die entstandene Chromverbindung durch Zugabe von Natrium- ehlorid und Salzsäure ab.
Das 8-Chlor-l-oxynaphthalin-5-sulfonsäure- methylamid kann beispielsweise wie folgt her gestellt werden Nach Veresterung der Oxygruppe der 8- Chlor-1- oxy-naphthalin-5-sulfonsäure mit p- Toluolsulfochlorid wird das Natriumsalz der Sulfonsäure durch Behandeln mit Phosphor- ehloriden in das entsprechende Sulfochlorid und dieses mit 1-Iethylamin in das
Sulfon- säuremethylamid übergeführt. Nach der Ver- seifung des p-Toluolsulfonsäurerestes durch Kochen mit verdünnter Natriumhydroxyd- lösung wird das 8-Chlor-l-oxynaphthalin-5- sulfonsäuremethylamid vom Schmelzpunkt 178-181 (unkorr.) erhalten.
Additional patent to main patent no. 308272. Process for the production of a metal-containing azo dye. [. It has been found that a new, valuable, metal-containing azo dye is obtained by using the monoazo dye of the formula
EMI0001.0007
lets chromium-releasing agents act in such a way that a chromium-containing azo dye is formed which contains two monoazo dye molecules bound to a chromium atom in a complex.
The new dye is a dark-colored substance when dried, which dyes wool from neutral or acetic acid bath in pure, blue, washable and lightfast shades.
Serving as the starting material, the above formula corresponding monoazo dye can lamids by coupling the 8-chloro-1-oxynaphthalene-5-sulfonsäuremethy with methods known per se, for. B. with means of hydrochloric acid and sodium nitrite diazotized 4-1Tethoxv-2-amino-1-oxpbenzene be prepared.
The treatment with the chromium-releasing agents takes place, as already mentioned, in such a way that a chromium-containing dye is created which contains two monoazo dye molecules bound to one atom of chromium in a complex. Accordingly leads. the chromizing is expediently carried out with such chromium-releasing agents and by such methods which experience has shown to provide complex chromium compounds of this composition.
It is generally advisable to use less than one, but at least half an atom of chromium on a molecule of a dye and / or to carry out the chromating in a weakly acidic to alkaline medium. Accordingly, those chromium compounds that are stable in an alkaline medium are particularly suitable for carrying out the process, such as, for example, those chromium compounds of aliphatic oxycarboxylic acids or preferably aromatic o-oxycarboxylic acids which contain the chromium in a complex bond .
The metallization is done with on part in the heat, open or under pressure, z. B. at the boiling point of the reaction mixture cal, optionally in the presence of appro-priate additives such. B. in the presence of salts of organic acids, bases, organic solvents or other agents promoting the complex formation.
Example: 7.3.9 parts of 4-methoxy-2-amino-1-oxybenzene are diazotized with 7 parts of sodium nitrite in the customary manner in the presence of 18 parts of 30% hydrochloric acid. The suspension of the diazo compound obtained is, with thorough stirring, to a solution, cooled to 10, of 29 parts of 8-chloro-1-oxy-naphthalen-5-sulfonic acid methylamide,
12 parts of sodium hydroxide and 60 parts of pyridine in 200 parts of water are allowed to flow in. After coupling has ended, the reaction mixture is diluted with 600 parts of water and the resulting dye is filtered off after adding 23 parts of 30-molar hydrochloric acid and washed with water. The dye is converted into the complex chromium compound, advantageously without prior drying.
For this purpose, the paraffin paste obtained according to the above is stirred with 700 parts of hot water. After the addition of 9 parts of sodium hydroxide and 100 parts of a solution of sodium cliromsalieylsaurem with a chromium content of 2.6%, the reaction mixture is heated to the boil for 4 hours under reflux.
If necessary, undissolved impurities are filtered off and the chromium compound formed is separated off from the filtrate by adding sodium chloride and hydrochloric acid.
The 8-chloro-1-oxynaphthalene-5-sulfonic acid methylamide can be prepared, for example, as follows. After esterification of the oxy group of 8-chloro-1-oxynaphthalene-5-sulfonic acid with p-toluenesulfonyl chloride, the sodium salt of sulfonic acid is treated by treatment with phosphorus ehloriden in the corresponding sulfochloride and this with 1-ethylamine in the
Sulfonic acid methylamide transferred. After the p-toluenesulfonic acid residue has been saponified by boiling with dilute sodium hydroxide solution, 8-chloro-1-oxynaphthalene-5-sulfonic acid methylamide with a melting point of 178-181 (uncorr.) Is obtained.
