Verfahren zur Darstellung von Schwefelfarbstoffen. Patentiert im Deutschen Reiche vom 1. April 1908 ab. Process for the preparation of sulfur dyes. Patented in the German Empire on April 1, 1908.
Es wurde gefunden, daß man Schwefelfarbstoffe , welche ungeheizte Baumwolle aus schwefelalkalihaltigem Bade in gelboliven bis oliven Tönen anfärben, erhält, wenn man Toluidin zusammen mit p-Phenylendiamin und Schwefel auf höhere Temperaturen erhitzt.It has been found that sulfur dyes, which are made from unheated cotton Coloring baths containing sulfur-alkali in yellow-olive to olive tones, obtained if one Toluidine heated to higher temperatures together with p-phenylenediamine and sulfur.
107 Teile p-Toluidin werden zusammen mit 162 Teilen ρ - Phenylendiarnin und 167 Teilen Schwefel am Rückflußkühier und unter Rühren während etwa 8 Stunden auf 220 bis 240 ° erhitzt. Die so erhaltene Schmelze wird heiß bis kochend in einer Mischung von 2460 Teilen kristallisiertem Schwefelnatrium und 1230 Teilen Wasser aufgelöst; wenn der Farbstoff vollständig in Lösung gegangen ist, wird er in der üblichen Weise, z. B. durch Ausblasen mit Luft oder durch Fällen mit Säuren, ausgeschieden, abgesaugt und getrocknet.107 parts of p-toluidine are together with 162 parts of ρ - phenylenediarnine and 167 parts of sulfur on the reflux refrigerator and with stirring heated to 220 to 240 ° for about 8 hours. The melt obtained in this way becomes hot to boiling in a mixture of 2460 parts of crystallized sodium sulphide and 1230 parts Dissolved water; when the dye is completely in solution it will turn into the usual way, e.g. B. excreted by blowing out with air or by precipitating with acids, vacuumed and dried.
Er färbt Baumwolle aus einem Bade, welches Schwefelalkali und Glaubersalz oder Kochsalz enthält, in olivfarbenen Tönen an.He dyes cotton from a bath which contains sulfuric alkali and Glauber's salt or table salt contains, in olive tones.
An Stelle des im Beispiel verwendeten p-Toluidins kann man sich auch des o- oder m-Toluidins oder der Acetyl- bzw. Formylverbindungen dieser drei Basen bedienen; ebenso kann man diejenigen Produkte verwenden, welche durch Einwirkung von Schwefel auf o-, m- oder p-Toluidin entstehen.Instead of the p-toluidine used in the example, one can also use the o- or use m-toluidine or the acetyl or formyl compounds of these three bases; in the same way one can use those products which are produced by the action of sulfur arise on o-, m- or p-toluidine.
Die Mengenverhältnisse zwischen Toluidin und ρ Phenylendiamin können variiert werden, wodurch die Nuancen beeinflußt werden, was auch durch die Dauer des Erhitzens in gewissem Grade bewirkt wird.The proportions between toluidine and ρ phenylenediamine can be varied, whereby the nuances are influenced, which also to a certain extent by the duration of the heating Grade is effected.
