Zusatz zum Patente 208560 vom 1. April 1908. Addendum to patent 208560 from April 1, 1908.
Patentiert im Deutschen Reiche vom 14. April 1908 ab. Längste Dauer: 31. März 1923.Patented in the German Empire on April 14, 1908. Longest duration: March 31, 1923.
Gegenstand des Patents 208560 ist ein Verfahren zur Darstellung von Schwefelfarbstoffen, welches darin besteht, daß o-, m- oder ρ-Toluidin oder deren Acetyl- bzw. Formylverbindüngen oder auch die Einwirkungsprodukte . von Schwefel auf die Toluidine zusammen mit p-Phenylendiamin ,und Schwefel auf höhere Temperatur erhitzt werden.The subject of patent 208560 is a process for the preparation of sulfur dyes, which consists in that o-, m- or ρ-toluidine or their acetyl or formyl compounds or the products of action. of sulfur on the toluidines along with p-phenylenediamine, and sulfur are heated to a higher temperature.
Es hat sich nun gezeigt, daß bei der Darstellung von Schwefelfarbstoffen nach diesem Verfahren das p-Phenylendiamin durch das p-Nitranilin ersetzt werden kann. Die Nuance der so erhaltenen Produkte ist im wesentlichen dieselbe wie diejenige der nach dem Verfahren des Hauptpatents erhaltenen Produkte.It has now been shown that in the representation of sulfur dyes after this Process that p-phenylenediamine can be replaced by p-nitroaniline. The nuance the product thus obtained is essentially the same as that obtained by the process of the main patent obtained products.
214 Teile o-Toluidin werden zusammen mit 420 Teilen p-Nitranilin und 1780 Teilen Schwefel unter Rühren am Rückflußkühler auf 220 bis 240 ° erhitzt. Die Schmelze ist nach etwa 8 Stunden fertig und wird in einer konz. Schwefelnatriumlösung gelöst, eventuell von Ungelöstem abfiltriert und der Farbstoff in der üblichen Weise, z. B. durch Ausblasen mittels Luft, abgeschieden, abgenutscht und getrocknet.214 parts of o-toluidine are together with 420 parts of p-nitroaniline and 1780 parts of sulfur to 220 with stirring on the reflux condenser heated to 240 °. The melt is ready after about 8 hours and is in a conc. Sodium sulfur solution dissolved, possibly filtered off from undissolved and the dye in the usual way, e.g. B. by blowing out with air, deposited, sucked off and dried.
Er erzeugt auf Baumwolle in einem Bade, welches Schwefelalkali und Glaubersalz oder Kochsalz enthält, olivfarbene Töne.He produces on cotton in a bath, which sulfur alkali and Glauber's salt or Table salt contains olive-colored tones.
