Description
Zusatzpatent zum Hauptpatent Nr. <B>110287.</B> Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man die diazotierte 2-Aminobenzol-l-p-toluolsulfon-4-sulfosäure mit 3-Aminonaphthalin-1,8-dikarbonsäure ver einigt. Der neue Farbstoff bildet ein brau nes Pulver, das sich in Wasser mit roter, in Schwefelsäure mit gelbbranner Farbe löst. Im Chromdruck auf Baumwolle erzeugt er reine, rote Töne.
<I>Beispiel:</I> <B>10,7</B> Teile 3-Aminonaplithalin-1,8-clilzar- bonsä,ureanllydrid werden mit Hilfe von<B>10</B> Teilen<B>30</B> %iger Natronlauge in<B>1.50</B> Teilen Wasser heiss gelöst, mit<B>10</B> Teilen Soda, ver setzt, abgekühlt und mit der aus<B>16,3</B> Teilen 2-Aminobenzol-l-p-toluols-Lilfon-4-sulfosäure hergestellten Dia-zoverbindung versetzt. Nach erfolgter Kupplung wird der Farbstoff a-us- gesalzen, filtriert und getrocknet.
Additional patent to main patent no. <B> 110287. </B> Process for the production of a new dye. It has been found that a new dye is obtained if the diazotized 2-aminobenzene-1-p-toluenesulfone-4-sulfonic acid is combined with 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a brown powder that dissolves in water with a red color and in sulfuric acid with a yellowish-brown color. In the chrome print on cotton it creates pure, red tones.
<I> Example: </I> <B> 10.7 </B> parts of 3-aminonaplithalin-1,8-clilzar- bonsa, ureanllydride are converted into <B> 10 </B> parts <B> 30 </B>% sodium hydroxide solution dissolved in <B> 1.50 </B> parts of hot water, mixed with <B> 10 </B> parts of soda, cooled and mixed with the <B> 16.3 </ B > Parts of 2-aminobenzene-lp-toluene-Lilfon-4-sulfonic acid produced dia-zo compound added. After coupling has taken place, the dye is salted out, filtered and dried.
