AKT.-GES. FÜR ANILIN-FABRIKATION in BERLIN. Verfahren zur Darstellung eines gelben Schwefelfarbstoffes.ACT.-TOTAL FOR ANILINE FACTORY in BERLIN. Process for the preparation of a yellow sulfur dye.
Zusatz zum Patente 166865 vom 13. Dezember 1904.Addendum to patent 166865 of December 13, 1904.
Patentiert im Deutschen Reiche vom 17. März 1905 ab. Längste Dauer: 12. Dezember 1919.Patented in the German Empire on March 17, 1905. Longest duration: December 12, 1919.
In der Patentschrift 166865 ist die Herstellung eines gelben Farbstoffes beschrieben, welcher durch Erhitzen einer Mischung von Acet-p-toluidin mit Benzidin und Schwefel auf höhere Temperatur erhalten wird. Es wurde nun gefunden, daß sich in diesem Verfahren das Acet-p-toluidin durch Acet-otoluidin ersetzen läßt. Das Verfahren ist das gleiche wie das in dem Beispiel des Hauptpatents beschriebene, und der erhaltene Farbstoff gleicht in allen wesentlichen Eigenschaften demjenigen des Hauptpatents.In the patent 166865 the production of a yellow dye is described, which by heating a mixture of acet-p-toluidine with benzidine and sulfur is obtained at a higher temperature. It has now been found that acet-p-toluidine is replaced by acet-otoluidine in this process can replace. The procedure is the same as that in the example of the main patent and the dye obtained is identical in all essential properties that of the main patent.
