Description

Verfahren zur Darstellung brauner Woll- und Lederfarbstoffe. Ersetzt man die für das Hauptpatent in Betracht kommenden N itr o@aniinodiplienvl aminsulfosäuren bei der Reaktion mit Chinonen durch solche Stilfosäuren, die erhalten werden mittels einsaitiger Kondensation von Diaminodiphenyl bzw. seinen Derivaten oder auch von Diaminodiphenylmethan bzw. seiner Derivaten mit Halogennitroarylsulfo- oder -carbonsätiren, so entstehen ebenfalls Farbstoffe, die zum Färben, namentlich von Leder. geeignet sind.Process for the preparation of brown wool and leather dyes. Replaces the N itr o @ aniinodiplienvl aminesulfonic acids that are eligible for the main patent in the reaction with quinones by such stilfo acids obtained by means of single-string condensation of diaminodiphenyl or its derivatives or of Diaminodiphenylmethane or its derivatives with Halogennitroarylsulfo- or -carbonsätiren, this also creates dyes that are used for dyeing, especially leather. suitable are.

So erhält man z. B. beim Erwärmen von Kondensationsprodukten aus t @Tol. Benzidin mit t ll-iol. Chlornitrobenzolsulfosä ure (1,d.,() mit Toluchinon einen Leder tabakbraun färbenden Farbstoff. Aus dem entsprechenden Diphenylinethanderivat wird ein Leder olivbraun färbender Farbstoff erhalten.So you get z. B. when heating condensation products from t @Tol. Benzidine with t ll-iol. Chloronitrobenzenesulfonic acid (1, d., () With toluquinone a dye that stains leather tobacco brown. From the corresponding diphenylinethane derivative a dye which dyes olive brown leather is obtained.
