Description
Verfahren zur Herstellung eines sauren Wollfarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines sauren Wollfarbstoffes, dadurch gekennzeichnet, dass man 4-Chlor-3-nitrozimmtsäure mit 4-Amino- diphenylamin-2-sulfonsäure kondensiert.
Der so erhaltene Farbstoff färbt Wolle in kräftig rotbraunen Tönen von bemerkens werten Echtheitseigenschaften.
Beispiel: 26,4 Teile 4-Aminodiphenylamin-2-sulfon- säure, 22,8 Teile 4-Chlor-3-nitrozimmtsäure und 16 Teile Natriumkarbonat werden mit etwa 200 Teilen Wasser etwa 30 Stunden zum Sieden erhitzt. Hierauf wird die tief braune Lösung zweckmässig zwecks Entfer nung von geringen Mengen unverändertem Ausgangsmaterial mit verdünnter Salzsäure angesäuert und filtriert. Dann wird der Farb stoff durch Aussalzen abgeschieden.
Die 4-Chlor-3-nitrozimmtsäure (farblose Nadeln vom Schmelzpunkt 184-185 C) kann zum Beispiel nach Perlon aus 4-Chlor- 3-nitrobenzaldehyd erhalten werden.
Process for the production of an acidic wool dye. The present patent relates to a process for the production of an acidic wool dye, characterized in that 4-chloro-3-nitro-cinnamic acid is condensed with 4-aminodiphenylamine-2-sulfonic acid.
The dye obtained in this way dyes wool in strong red-brown shades with remarkable fastness properties.
Example: 26.4 parts of 4-aminodiphenylamine-2-sulfonic acid, 22.8 parts of 4-chloro-3-nitrozinntsic acid and 16 parts of sodium carbonate are heated to the boil with about 200 parts of water for about 30 hours. The deep brown solution is then appropriately acidified with dilute hydrochloric acid and filtered to remove small amounts of unchanged starting material. Then the dye is deposited by salting out.
4-chloro-3-nitrobenzaldehyde (colorless needles with a melting point of 184-185 ° C.) can be obtained from 4-chloro-3-nitrobenzaldehyde, for example according to Perlon.
