Description
Terfahren zur Herstellung einer haltbaren iazoverbindung. Es wurde gefunden, dass man eine halt bare Diazoverbindung erhält, wenn man aus einer Lösung von diazotiertem ortho-Chlor- anilin durch eine Zinkverbindung ein Chlor zinkdoppelsalz der Formel: 2 Ce H4 Cl N2 Cl -j- Zn Ch abscheidet.
Die abgeschiedene feuchte Verbindung kann durch Vermischen mit geeigneten was serbindenden Stoffen oder .durch Trocknen in der Wärme in trockene Form gebracht werden und stellt dann ein weisses Kristall pulver dar, ist in Wasser gut und fast farb los löslieh und besitzt eine gute Beständig keit auch bei höheren Temperaturen, kuppelt leicht mit Kupplungskomponenten und ist daher zur Herstellung von Färbungen auf der Faser wertvoll.
<I>Beispiel:</I> 765 Teile ortho-Chloranilin werden mit 2400 Teilen Salzsäure von 20 Gewichtspro zent und <B>1035</B> Teilen Natriumnitiitlösung von 40 % bei niedriger Temperatur diazo- tiert. Die Dia.zolösung wird mit 435 Teilen Chlorzink versetzt und dann die bereits teil weise erfolgte Abscheidung der Diazoverbin- dung mit 470 Teilen Kochsalz vervollstän digt.
Die in kristalliner Form abgeschiedene Diazoverbindung wird durch Filtrieren von der Brühe getrennt und entweder durch Ver- mahlen mit geeigneten wasserbindenden Stof fen, wie mehr oder weniger stark entwässer tem Aluminiumsulfat oder Alaun oder naphthalintetrasulfosaurem Natrium in trok- kenes Pulver verwandelt, oder in der Wärme bei 40 bis 50 vorsichtig getrocknet.
Die in der Wärme getrocknete Diazoverbindung wird zweckmässig noch mit einem geeigneten Einstellmittel, wie NatriumehloTid, Natrium sulfat, Aluminiumsulfat oder Alaun, die auch teilweise entwässert sein können, ent wässertem Magnesium-Kaliumchlorid oder einem Arylsulfonat usw. und mit etwaigen weiteren Färbereihilfsstoffen, wie Chrom oder Kupfersalze oder Benetzungsmittel, ein gestellt.
The process of making a durable iazo compound. It has been found that a permanent diazo compound is obtained if a chlorine zinc double salt of the formula: 2 Ce H4 Cl N2 Cl -j- Zn Ch is deposited from a solution of diazotized ortho-chloroaniline with a zinc compound.
The separated moist compound can be brought into dry form by mixing with suitable binding substances or by drying in the heat and then represents a white crystal powder, is easily soluble in water and almost colorless and has good resistance even with higher temperatures, easily couples with coupling components and is therefore valuable for producing dyeings on the fiber.
<I> Example: </I> 765 parts of ortho-chloroaniline are diazotized with 2400 parts of hydrochloric acid of 20 percent by weight and <B> 1035 </B> parts of sodium nitrate solution of 40% at low temperature. 435 parts of zinc chloride are added to the diazo solution and the diazo compound which has already partially been deposited is then completed with 470 parts of common salt.
The diazo compound deposited in crystalline form is separated from the broth by filtration and either converted into a dry powder by grinding with suitable water-binding substances, such as more or less dehydrated aluminum sulfate or alum or sodium naphthalenetetrasulfonic acid, or when heated 40 to 50 carefully dried.
The diazo compound, dried in the heat, is expediently treated with a suitable setting agent such as sodium sulfate, aluminum sulfate or alum, which can also be partially dehydrated, ent watered magnesium-potassium chloride or an aryl sulfonate, etc. Copper salts or wetting agents, one set.
