KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es wurde gefunden, daß man einen schönen roten Azofarbstoff erhält, welcher sich sehr gut zur Darstellung roter Lacke eignet, indem man die Diazoverbindung der o-Chlorm-toluidin-p-sulfosäure umsetzt mit ß-Naphthol. It has been found that a beautiful red azo dye is obtained which is very different well suited for the representation of red lacquers by adding the diazo compound of o-chlorom-toluidine-p-sulfonic acid reacts with ß-naphthol.
Die bisher unbekannte o-Chlor-m-toluidinp-sulfosäure The previously unknown o-chloro-m-toluidine p-sulfonic acid
(CH3: NH2 (CH 3 : NH 2
Cl: SO3H--Cl: SO 3 H--
:3:6:4;: 3: 6: 4;
erhält man durch Reduktion der o-Chlor-mnitrotoluol-p-sulfosäure, welche ihrerseits durch Nitrieren der o-Chlortoluol-p-sulfosäureis obtained by reducing the o-chloro-mnitrotoluene-p-sulfonic acid, which in turn by nitrating the o-chlorotoluene-p-sulfonic acid
. zu erhalten ist. Während die Salze der m-Nitro-o-chlortoluol-p-sulfosäure in Wasser leicht löslich sind, sind die der reduzierten Säure bedeutent schwerer löslich und leicht in kristallisierter Form zu erhalten. Die o-Chlor-m-toluidin-p-sulfosäure bildet als freie Säure ein weißes Pulver, welches in Wasser ziemlich schwer löslich ist. Die Lösung der Säure in essigsaurem Natron wird durch Zusatz von Eisenchlorid braun gefärbt. Die Diazoverbindung ist fast farblos und fällt aus konzentrierter Lösung zum Teil aus.. is to be obtained. While the salts of m-nitro-o-chlorotoluene-p-sulfonic acid are readily soluble in water, those of the reduced acid are significantly less soluble and easy in crystallized form. The o-chloro-m-toluidine-p-sulfonic acid forms a white powder as the free acid, which is rather sparingly soluble in water. The solution to the Acid in baking soda turns brown when iron chloride is added. the Diazo compound is almost colorless and partially precipitates from concentrated solution.
Beispiel für die Darstellung des Farbstoffes: 22,15 kg o-Chlortoluidin-p-solfosäure werden in der äquivalenten Menge Soda gelöst, die Lösung schnell abgekühlt und so viel Salzsäure zugesetzt, daß die Masse . gerade sauer 3> reagiert. Die Sulfosäure scheidet sich als feines weißes Pulver aus. Man gibt darauf 22 kg Salzsäure von etwa 33 Prozent H Cl-Gehalt hinzu und diazotiert mit 7 kg Nitrit. Die Diazoverbindung fällt zum Teil aus. 3.s Darauf läßt man einlaufen in eine kalte Lösung von 14,6 kg ß-N.aphthol, gelöst in 12 kg Natronlauge von 400 B. und 10 kg Soda.- Nach etwa 12 Stunden abfiltriert und getrocknet bildet der Farbstoff in staubfeiner 4 > Form ein rotes Pulver, welches im Wasser nur in der Hitze etwas löslich ist. Die aus dem Farbstoff erhältlichen Lacke zeichnen sich durch ihre Nuance und Echtheit aus.Example for the representation of the dye: 22.15 kg of o-chlorotoluidine-p-solfonic acid are dissolved in the equivalent amount of soda, the solution is quickly cooled and so much hydrochloric acid is added that the mass. just angry 3> reacts. The sulfonic acid separates out as a fine white powder. 22 kg of hydrochloric acid with about 33 percent HCl content are then added and the mixture is diazotized with 7 kg of nitrite. The diazo compound fails in part. Then 3.s allowed to run into a cold solution of 14.6 kg ß-N.aphthol dissolved in 12 kg of sodium hydroxide of 40 and 10 kg 0 B. Soda.- filtered off after about 12 hours and dried in the dye forms fine dust 4> Form a red powder, which is only slightly soluble in water in the heat. The paints obtainable from the dye are distinguished by their nuance and authenticity.
