Verfahren zum Haltbarmaehen von Diazolösungen.
Es ist bekannt, dass in Diazolösungen, wie man sie zur Herstellung von Azofarbstoffen auf der Faser verwendet, je nach der Haltbarkeit der Diazoverbindung nach kürzerem oder längerem Stehen sich Ausscheidungen von Zersetzungsprodukten bilden, welche die Reibechtheit der Färbung, insbesondere bei Apparatfärbungen, sehr ungünstig beeinflussen.
Es wurde nun gefunden, dass das Auftreten dieser Ausscheidungen praktisch dadurch verhindert werden kann, dass man den Diazolösungen Dispergier-oder Emulgiermittel, die bei saurer Reaktion beständige Lösungen bilden, zusetzt. Als Dispergier-bzw. Emulgiermittel seien beispielsweise genannt : gereinigte Sulfitablauge, die Umsetzungsprodukte von Carbonsäuren aliphatischer, cycloaliphatischer oder aromatisch-aliphatischer Natur mit organischen Aminosulfonsäuren, deren Herstellung den Gegenstand der englischen Patente Nr. 341053,343524 und 343899 bildet ; ferner Verbindungen, die man dadurch erhält, dass man in organische Verbindungen, die eine oder mehrere Oxy-, Carboxy-oder Aminogruppen enthalten, Polyglylcolätherreste mit 4 oder mehr Äthylengruppen einführt (vgl. franz.
Patent Nr. 727202) oder auch esterartige Kondensationsprodukte, wie sie nach dem Verfahren des franz. Patentes Nr. 705801 erhalten werden können.
Die Menge des zuzusetzenden Dispergier-oder Emulgiermittels kann in weiten Grenzen schwanken, jedoch genügen im allgemeinen 1-3 g auf l . Die Lösungen bleiben dadurch während der ganzen Dauer ihres Gebrauches klar und zeigen eine sehr gute Haltbarkeit.
Beispiel : 2 g 4-Chlor-l-methyl-2-aminobenzol werden in der üblichen Weise diazotiert, mit essigsaurem Natrium abgestumpft und nach dem Auffüllen auf l mit 1 g Oleylmethyltaurin (hergestellt nach Beispiel 4 des engl. Patentes Nr. 343899) versetzt. Mit dieser Lösung wird Baumwolle, welche mit 2-oxynaphthalin-3-carbonsänre-o-toluidid imprägniert ist, in der üblichen Weise entwickelt.
Die in derselben Weise hergestellte Diazolösung zeigt ohne den Zusatz von Oleylmethyltaurin schon nach kurzer Zeit (etwa %-1 Stunde) rosa gefärbte, flockige Ausscheidungen.
An Stelle des Oleylmethyltaurin kann mit demselben Erfolg z. B. auch Oleylhydroxyäthannatriumsulfonat verwendet werden (siehe z. B. franz. Patent Nr. 705 081) oder Produkte, die durch Einwirkung von 20 Mol Äthylenoxyd auf 1 Mol Octodecylalkohol oder 1 Mol von Oleylalkohol (siel. e z. B. franz. Patent Nr. 727702) erhalten werden.

Process for the preservation of diazo solutions.
It is known that in diazo solutions, such as those used for the production of azo dyes on the fiber, depending on the durability of the diazo compound, after a shorter or longer period of standing, decomposition products form, which have a very unfavorable effect on the rubbing fastness of the dyeing, especially in the case of machine dyeing .
It has now been found that the occurrence of these precipitates can practically be prevented by adding dispersants or emulsifiers, which form stable solutions in the event of an acid reaction, to the diazo solutions. As a dispersing or. Examples of emulsifiers are: purified sulphite waste liquor, the reaction products of carboxylic acids of aliphatic, cycloaliphatic or aromatic-aliphatic nature with organic aminosulphonic acids, the production of which is the subject of English patents 341053,343524 and 343899; Furthermore, compounds obtained by introducing polyglylcolether radicals with 4 or more ethylene groups into organic compounds which contain one or more oxy, carboxy or amino groups (cf.
Patent No. 727202) or ester-like condensation products, as they are according to the method of the French. Patent No. 705801 can be obtained.
The amount of dispersant or emulsifier to be added can vary within wide limits, but 1-3 g per liter are generally sufficient. The solutions thus remain clear for the entire duration of their use and have a very good shelf life.
Example: 2 g of 4-chloro-1-methyl-2-aminobenzene are diazotized in the usual way, blunted with acetic acid sodium and, after making up to 1, mixed with 1 g of oleylmethyltaurine (prepared according to Example 4 of English Patent No. 343899) . Cotton impregnated with 2-oxynaphthalene-3-carboxylic acid o-toluidide is developed with this solution in the usual way.
The diazo solution prepared in the same way shows, without the addition of oleylmethyltaurine, pink-colored, flaky precipitates after a short time (approx.
Instead of oleylmethyltaurine, z. B. Oleylhydroxyäthannatriumsulfonat can be used (see z. B. French. Patent No. 705 081) or products that by the action of 20 moles of ethylene oxide on 1 mole of octodecyl alcohol or 1 mole of oleyl alcohol (siel. E. B. French. Patent No. 727702).
