  Verfahren     zum        Haltbarmachen    von     Diazolösungen.       Es ist bekannt, dass in     Diazolösungen,     wie man sie zur Herstellung von     Azofarb-          stoffen    auf der Faser verwendet, je nach der  Haltbarkeit der     Diazoverbindung    nach kür  zerem oder längerem Stehen sich Ausschei  dungen von Zersetzungsprodukten bilden, wel  che die Reibechtheit der Färbung, insbeson  dere bei     Apparatfärbungen,    sehr ungünstig  beeinflussen.  
  Es wurde nun gefunden, dass das Auf  treten dieser Ausscheidungen praktisch da  durch verhindert werden kann, dass man den       Diazolösungen        Dispergier-    oder     Emulgiermittel,     die bei saurer Reaktion beständige Lösungen  bilden, zusetzt.
   Als     Dispergier-        bezw.        Emul-          giermittel    seien beispielsweise genannt: ge  reinigte     Sulfitablauge,    die Umsetzungspro  dukte von     garbonsäuren        aliphatischer,        cyclo-          aliphatischer    oder     aromatisch-alipbatischer     Natur mit organischen     Aminosulfonsäuren,     deren Herstellung den Gegenstand der eng  lischen Patente 341053, 843524 und 343899    bildet, ferner Verbindungen, die man dadurch  erhält, dass man in organische Verbindungen,  die eine oder mehrere     Oxy-,
          Carboxy-    oder       Aminogruppen    enthalten,     Polyglycolätherreste     mit 4 oder mehr     .Äthylengruppen    einführt       (vergl.    franz. Patent 727202) oder auch     ester-          artige        Kondensationsprodukte,    wie sie nach  dem     Verfahren    des franz. Patentes 705801  erhalten werden können.  
  Die Menge des zuzusetzenden     Dispergier-          oder        Emulgiermittels    kann in weiten Grenzen  schwanken, jedoch genügen im allgemeinen  1-3     gr    auf 1 Liter. Die Lösungen bleiben  dadurch während der ganzen Dauer ihres Ge  brauches klar und zeigen eine sehr gute Halt  barkeit.    <I>Beispiel:</I>  2     gr        4-Chlor-l-methyl-2-aminobenzol    wer  den in der üblichen Weise dianotiert, mit  essigsaurem Natrium abgestumpft und nach  dem     Auffüllen    auf 1 Liter mit 1     gr    Oleyl-           methyltaurin    (hergestellt nach Beispiel 4 des  englischen Patentes 343899) versetzt.
   Mit  dieser Lösung kann Baumwolle, welche mit       2-Oxynaphthalin-3-karbonsäure-o-tolüidid    im  prägniert ist, in der üblichen Weise     entwik-          kelt        werden,-          Die    in derselben Weise hergestellte     Diazo-          lösung    zeigt ohne den Zusatz von     Oleyl-          methyltaurin    schon nach kurzer Zeit (etwa       1/z-1    Stunde) rosa gefärbte, flockige Aus  scheidungen.  
  An Stelle des     Oleylmethyltaurins    kann mit  demselben Erfolg z. B. auch     Oleylhydroxy-          äthannatriumsulfonat    verwandt werden (siehe  z. B. franz. Patent     705081_)    oder Produkte, die    durch Einwirkung von 20     Mol        Äthylenogyd     auf 1     Mol        Octodecyalalkohol,    oder     'l        Mol    von       Oleylalkohol    (siehe z. B. franz. Patent 727702)  erhalten werden.
  Process for preserving 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 shelf life of the diazo compound, after a shorter or longer period of standing, decomposition products form, wel che the rubbing fastness of the dye, in particular in the case of apparatus coloring, have a very unfavorable effect.
  It has now been found that the occurrence of these precipitations 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 aliphatic, cycloaliphatic or aromatic-aliphatic nature with organic aminosulphonic acids, the production of which is the subject of English patents 341053, 843524 and 343899, and also compounds that are obtained by converting one or more oxy-,
          Contain carboxy or amino groups, polyglycol ether radicals with 4 or more. Ethylene groups (cf. French. Patent 727202) or ester-like condensation products, as they are according to the method of French. Patent 705801 can be obtained.
  The amount of the dispersing or emulsifying agent to be added can vary within wide limits, but generally 1-3 g per 1 liter are sufficient. As a result, the solutions remain clear for the entire duration of their use and have a very good shelf life. <I> Example: </I> 2 grams of 4-chloro-l-methyl-2-aminobenzene are dianotized in the usual way, blunted with sodium acetate and, after filling up to 1 liter, with 1 gram of oleylmethyltaurine (manufactured according to Example 4 of English patent 343899).
   With this solution cotton, which is impregnated with 2-oxynaphthalene-3-carboxylic acid-o-toluidide, can be developed in the usual way. The diazo solution produced in the same way shows without the addition of oleylmethyltaurine after a short time (about 1 / z-1 hour) pink colored, flaky excretions.
  Instead of oleylmethyltaurine, z. B. Oleylhydroxy- äthannatriumsulfonat can be used (see z. B. French. Patent 705081_) or products that are produced by the action of 20 moles of Ethylenogyd on 1 mole of octodecyl alcohol, or 1 mole of oleyl alcohol (see, for example, French. Patent 727702 ) can be obtained.
