PATENTAMT.PATENT OFFICE.
Bei der Fortsetzung der Untersuchungen über die aus der diazotirten Toluylendiaminsulfosäure (CiZ8: NH2 -.SO3H: NH2 = 1:2:4:6) darstellbaren Azofarbstoffe hat sich ergeben, dafs nicht nur die sogenannten ρ - Diamine (Benzidin, p-Phenylendiamin etc.) zur Herstellung von Baumwolle direct färbenden Azofarbstoffen brauchbar sind, sondern dafs auch gewisse Derivate von m-Diaminen zur Erreichung desselben Zweckes geeignet sind. So sind, wie aus den Patenten Nr. 65863 und 70147 ersichtlich ist, braune, orangefarbene und gelbe, Baumwolle direct färbende Azofarbstoffe mit Hülfe der diazotirten Toluylendiaminsulfosäure, welche sich vom 1:2:6 m -Toluylendiamin ableitet, dargestellt worden. Bei der weiteren Ausarbeitung dieses Gebietes wurde nun gefunden, dafs sich der in der Patentschrift Nr. 70147 beschriebene orangefarbene Farbstoff: In the continuation of the investigations into the azo dyes which can be prepared from the diazotized toluenediaminesulfonic acid (CiZ 8 : NH 2 -SO 3 H: NH 2 = 1: 2: 4: 6), it has been shown that not only the so-called ρ-diamines (benzidine , p-phenylenediamine, etc.) can be used for the production of azo dyes which directly dye cotton, but also that certain derivatives of m-diamines are suitable for the same purpose. Thus, as can be seen from Patents Nos. 65863 and 70147, brown, orange and yellow azo dyes directly dyeing cotton with the aid of the diazotized toluenediamine sulfonic acid, which is derived from 1: 2: 6 m -toluenediamine, have been prepared. In the further elaboration of this area it has now been found that the orange-colored dye described in patent specification No. 70147 is:
N=NC10H6-NH2 Η(NHN = NC 10 H 6 -NH 2 Η (NH
noch mit einem Molecül einer diazotirten aromatischen Sulfosäure, z. B. Diazonaphtionsäure, verbindet und dabei einen sehr echten, gelbbraunen Baumwollfarbstoff liefert. nor with a molecule of a diazotized aromatic sulfonic acid, e.g. B. Diazonaphtionic acid, connects and delivers a very real, yellow-brown cotton dye.
Zu seiner Herstellung verfährt man folgendermafsen: To manufacture it, proceed as follows:
Auf den nach den Angaben des Patentes Nr. 70147 aus 10,1 kg Toluylendiaminsulfosäure, 9 kg salzsaurem ß-Naphtylamin und 10,3 kg schwefelsaurem m-Phenylendiamin dargestellten Farbstoff läfst man die aus 13 kg naphtionsaurem Natrium bereitete Diazonaphtionsäure in wässeriger Lösung einen Tag lang unter Umrühren einwirken; dann wird der neue Farbstoff nach dem Erwärmen der Reactionsmasse und Neutralisiren mit Soda ausgesalzen, filtrirt, abgeprefst und getrocknet.On the according to the information of patent no. 70147 from 10.1 kg of toluenediaminesulfonic acid, 9 kg of hydrochloric acid ß-naphthylamine and 10.3 kg of sulfuric acid m-phenylenediamine shown The diazonaphthionic acid prepared from 13 kg of sodium naphthoic acid is dyestuff act in an aqueous solution for a day while stirring; then the new one After heating the reaction mass and neutralizing with soda, salt out the dye, filtered, pressed and dried.
Der neue Farbstoff bildet ein tief dunkelbraunes Pulver, welches sich in Wasser mit gelbbrauner, in concentrirter Schwefelsäure mit schmutzig violetter Farbe löst. Aus seiner wässerigen Lösung scheidet Salzsäure die Farbstoffsäure in braunen Flocken aus. Er färbt ungeheizte Baumwolle gelbbraun. Ersetzt man in dem vorhin beschriebenen Verfahren das m-Phenylendiamin durch, die äquivalente Menge Toluylendiamin, so erhält man einen Farbstoff, der ungeheizte Baumwolle gelbbraun von klarer Nuance färbt.The new dye forms a deep dark brown powder that dissolves in water yellow-brown dissolves in concentrated sulfuric acid with a dirty violet color. From his aqueous solution, hydrochloric acid separates the dye acid in brown flakes. He colors unheated cotton yellow-brown. If you replace the in the procedure described above m-phenylenediamine through, the equivalent amount of tolylenediamine, you get a dye, the unheated cotton dyes yellow-brown with a clear shade.
