PATENTAMT.PATENT OFFICE.
Bei der Einwirkung von Rhodansalzen auf Dinitro-m-dichlorbenzol in Gegenwart eines geeigneten Lösungs- oder Verdünnungsmittels, wie z. B. Alkohol, Aceton u. s. w., werden beide Ghloratome durch die Rhodanreste ersetzt, und es entsteht m-Dinitrodirhodanbenzol, ein aus Alkohol in blafsgelben Blättchen krystallisirender und bei 1850 unter Zersetzung schmelzender Körper. Behandelt man dieses Dinitrodirhodanbenzol z. B. in alkoholischer Lösung bei Anwesenheit von Natriumacetat u.s.w. mit o- oder p-Amidophenol bezw. Derivaten des letzteren, so bilden sich unter Abspaltung von Rhodanwasserstoff Rhodanderivate der o-p-Dinitrooxydiphenylamine, welche sich beim Erkalten abscheiden, und denen ihrer Entstehung nach die allgemeine FormelWhen rhodan salts act on dinitro-m-dichlorobenzene in the presence of a suitable solvent or diluent, such as. As alcohol, acetone, etc., are both replaced by the Ghloratome thiocyanate radicals, and creates m-Dinitrodirhodanbenzol, a krystallisirender from alcohol in blafsgelben flakes and melting at 185 0 with decomposition body. If you treat this Dinitrodirhodanbenzol z. B. in alcoholic solution in the presence of sodium acetate, etc. with o- or p-amidophenol respectively. Derivatives of the latter, rhodan derivatives of op-dinitrooxydiphenylamines are formed with elimination of rhodanic acid, which are separated out on cooling and which, according to their formation, have the general formula

Die vom o- und p-Amidophenol derivirenden Verbindungen bilden rothe, oberhalb 2500 bezw. 2200 schmelzende Krystalle, während diejenigen Producte, welche sich von der Sulfo- oder Carbonsäure des p-Amidophenols ableiten, in Form von rothen, krystallinischen Niederschlägen erhalten werden, welche beim Erhitzen ohne vorheriges Schmelzen verkohlen.comes, in which X is an amidophenol radical. The compounds derivirenden from o- and p-amidophenol form red, above 250 0 respectively. 220 0 melting crystals, while those products which are derived from the sulfo or carboxylic acid of p-amidophenol are obtained in the form of red, crystalline precipitates which char on heating without prior melting.
Die auf diese Weise dargestellten Rhodanderivate des o-p-Dinitro-p^oxydiphenylamins, seiner Sulfo- und Carbonsäure liefern nun in der Schwefel-Schwefelalkalischmelze Farbstoffe, welche ungeheizte Baumwolle in grünlich grauschwärzen Tönen anfärben. Diese Färbungen ändern jedoch schon beim Liegen an der Luft, rascher noch beim Dämpfen in Gegenwart von Sauerstoff oder beim Behandeln mit alkalischen Oxydationsmitteln, wie z. B. Natriumsuperoxyd, ihre Nuance und verwandeln sich in lebhafte indigblaue Töne, welche den höchsten Anforderungen in Bezug auf Waschechtheit, Beständigkeit gegen Alkalien und Säuren u. s. w. genügen. Besonders werthvolle Farbstoffe wurden bisher erhalten bei Verwendung der Condensationsproducte aus 1 Mol. Dinitrodirhodanbenzol uud 1 Mol. p-Amidophenol, p-Amidophenol-o-sulfosäure und p-Amidosalicylsäure.The rhodan derivatives of o-p-dinitro-p ^ oxydiphenylamine presented in this way, its sulpho and carboxylic acids now produce dyes in the sulfur-alkali metal melt, which dye unheated cotton in greenish gray-black tones. These colorations change, however, already when lying in the air, more rapidly even when steaming in the presence of Oxygen or when treating with alkaline oxidizing agents, such as. B. sodium peroxide, their nuance and transform into lively indig blue tones, which meet the highest requirements in terms of wash fastness, resistance to alkalis and acids, etc. are sufficient. Particularly valuable dyes have hitherto been obtained using the condensation products from 1 mol. dinitrodirhodanbenzene and 1 mol. p-amidophenol, p-amidophenol-o-sulfonic acid and p-amidosalicylic acid.
300 Theile krystallisirtes Schwefelnatriurn, 80 Theile gepulverter Schwefel und i5oTheile Wasser werden in einem mit Rührer und OeI-bad versehenen eisernen Kessel unter Erwärmen gelöst. Nach dem Erkalten auf ca. 40° werden unter Rühren allmählich 100 Theile des aus 1 Mol. Dinitrodirhodanbenzol und ι Mol. p-Amidophenol erhaltenen o-p-Dinitrom-rhodan-p^oxydiphenylamins eingetragen, wobei die Temperatur nicht über 90 bis ioo° steigen soll.300 parts crystallized sodium sulphide, 80 parts powdered sulfur and 150 parts Water are heated in an iron kettle equipped with a stirrer and an oil bath solved. After cooling to about 40 °, 100 parts gradually increase with stirring of the o-p-dinitrom-rhodane-p ^ oxydiphenylamine obtained from 1 mol. Dinitrodirhodanbenzol and ι mol. p-Amidophenol entered, whereby the temperature does not exceed 90 to 100 ° should rise.

In genau der gleichen Weise verfährt man unter Verwendung der anderen oben erwähnten Diphenyläminderivate.Proceed in exactly the same way using the others mentioned above Diphenylamine derivatives.
Die Eigenschaften der einzelnen so erhaltenen Farbstoffe liegen äufserst nahe bei einander; die Farbstoffe lösen sich in Wasser bei Gegenwart von Schwefelalkali mit reinblauer Farbe und werden aus der wässerigen Lösung durch Chlorkalium als bläuliche, durch Chlorammonium oder durch Säuren als dunkle, flockige Niederschläge gefällt. In ihren färberischen Eigenschaften zeigen die Farbstoffe nur geringe Unterschiede in . Bezug auf Farbstärke und Nuance, und zwar so, dafs das p-Amidophenolproduct nach alkalischer Oxydation auf der Faser das rötheste, das p-Amidosalicylsäureproduct bei gleicher Behandlung das grünstichigste. Blau liefert; die Nuance des p-Amido-.phendlsulfosäureproductes liegt zwischen diesen beiden.The properties of the individual dyes obtained in this way are extremely close to one another; the dyes dissolve in water in the presence of sulfur alkali with a pure blue color and are changed from the aqueous solution by potassium chloride to bluish, by chlorammonium or precipitated by acids as dark, flaky precipitates. In their dyeing The dyes show only minor differences in properties. Regarding color strength and Nuance, in such a way that the p-amidophenol product after alkaline oxidation on the Fiber the redest, the p-amidosalicylic acid product the greenest with the same treatment. Blue supplies; the shade of the p-amido-.phendlsulfosäureproductes lies between these two.
