Description
Zusatzpatent zum Hauptpatent Nr. 110287. Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man diazotierte 1-Amino-4-nitrobenzol-2-sulfosäure mit 3 Aminonaphthalin-1,8-dikarbonsäure vereinigt. Der neue Farbstoff bildet ein schwarz braunes Pulver, das sich in Wasser mit vio letter, in Schwefelsäure mit gelbbrauner Farbe löst. Er färbt Wolle aus saurem Bade in violetten Tönen. Im Chromdruck auf Baumwolle erzeugt er violette Töne.
Beispiel: 10,7 Teile 3-Aminona.phthalin-1,8-dikar- bonsKureanhydrid werden mit Hilfe von 10 Teilen 30 %iger Natronlauge in 150 Teilen Wasser heiss gelöst, mit 10 Teilen Soda ver setzt, abgekühlt und mit der aus<B>10,9</B> Teilen 1-Amino-4-nitrobenzol-2-sulfosäure hergestell- ten Diazoverbindung versetzt. Nach erfolg ter Kupplung wird der Farbstoff ausgesal- zen, filtriert und getrocknet.
Additional patent to main patent no. 110287. Process for the production of a new dye. It has been found that a new dye is obtained when diazotized 1-amino-4-nitrobenzene-2-sulfonic acid is combined with 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a black-brown powder that dissolves in water with violet letter, in sulfuric acid with yellow-brown color. He dyes wool from an acid bath in shades of purple. In the chrome print on cotton it creates violet tones.
Example: 10.7 parts of 3-Aminona.phthalin-1,8-dikar- bonsKureanhydrid are dissolved with the help of 10 parts of 30% sodium hydroxide solution in 150 parts of hot water, mixed with 10 parts of soda, cooled and treated with the from <B > 10.9 parts of 1-amino-4-nitrobenzene-2-sulfonic acid produced diazo compound were added. After coupling has taken place, the dye is salted out, filtered and dried.
