Description
Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff erhält, wenn man die Diazover- bindung des 1-Aminobenzol-4-carbonsäure-,3- oxäthyla.mids, 1-o-Chlorphenyl-3-methyl-5- pyrazolon und Maleinsäureanhydrid derart aufeinander einwirken lässt,
dass der Azofarb- stoff aus diazotiertem 1-Aminobenzol-4-earbon- s i iltire -[i-oxyäthylamid und 1-o-Chlorphenyl-3- methyl-5-pyrazolon entsteht und das Malein- säureanhydrid mit der Oxygruppe des Carbon- säureoxyamids den sauren Maleinsäureester bildet.
Der so erhaltene Farbstoff bildet ein gel bes Pulver, das sich in Wasser löst und Acetatkunstseide in gelben Tönen färbt.
<I>Beispiel:</I> 180 Teile 1-Aminobenzol-4-carbonsäure-,l- oxäthylamid werden durch Zugabe von 250 Teilen Salzsäure vom spezifischen Gewicht 1,15 und 69 Teilen Natriumnitrit in eiskalter wässriger Lösung diazotiert. Diese Diazolösung gibt man unter Rühren zu einer mit einem säurebindenden Mittel wie Natriumacetat oder Natriumcarbonat versetzten wässrigen Lösung von 208 Teilen 1-o-Chlorphenyl-3-methyl-5- pyrazolon und 40 Teilen Natriumhydroxyd zu.
Der Farbstoff bildet sich innert kurzer Zeit. Nachdem die Umsetzung beendet ist, wird er filtriert und gewaschen und getrocknet.
5 Teile dieses Farbstoffes werden in 5 Teile geschmolzenes Maleinsäureanhydrid eingetra gen. Man lässt während etwa 2 Stunden bei <B>90-1001</B> C rühren, wobei die Masse langsam fester wird. Sie wird nun im Wasser unter Zusatz von Alkali, z. B. Ammoniak gelöst und mit einem Salz, z. B. Natriumchlorid, der Farb stoff ausgefällt.
Er bildet in trockenem Zu stande ein gelbes Pulver, das sich in Wasser mit gelber Farbe löst und das Acetatkunst- seide in denselben Tönen färbt.
Process for the production of a new azo dye. It has been found that a new azo dye is obtained if the diazo compound of 1-aminobenzene-4-carboxylic acid, 3-oxäthyla.mids, 1-o-chlorophenyl-3-methyl-5-pyrazolone and maleic anhydride on one another lets act
that the azo dye is formed from diazotized 1-aminobenzene-4-earbon- si iltire - [i-oxyethylamide and 1-o-chlorophenyl-3-methyl-5-pyrazolone and the maleic anhydride with the oxy group of the carboxylic acid oxyamide denies forms acidic maleic acid ester.
The dye thus obtained forms a yellow powder that dissolves in water and dyes acetate rayon in yellow tones.
<I> Example: </I> 180 parts of 1-aminobenzene-4-carboxylic acid, l-oxethylamide are diazotized by adding 250 parts of hydrochloric acid with a specific gravity of 1.15 and 69 parts of sodium nitrite in an ice-cold aqueous solution. This diazo solution is added with stirring to an aqueous solution of 208 parts of 1-o-chlorophenyl-3-methyl-5-pyrazolone and 40 parts of sodium hydroxide to which an acid-binding agent such as sodium acetate or sodium carbonate has been added.
The dye forms within a short time. After the reaction is over, it is filtered and washed and dried.
5 parts of this dye are introduced into 5 parts of molten maleic anhydride. The mixture is left to stir for about 2 hours at 90-1001 C, the mass slowly solidifying. It is now in the water with the addition of alkali such. B. ammonia and dissolved with a salt, e.g. B. sodium chloride, the dye precipitated.
When dry it forms a yellow powder which dissolves in water with a yellow color and colors the acetate artificial silk in the same shades.
