Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 152880. Verfahren zur Herstellung eines chromhaltigen Farbstoffes. Es wurde gefunden, dass ein neuer chrom- haltiger Farbstoff, der auf jede chromierbare Gruppe des Farbstoffmoleküls 1 Atom Chrom enthält, erhalten wird, wenn man den Farb stoff aus dianotierter 1- Aminonaphtalin - 4 - sulfosäure und 1-Oxybenzol-2-carbonsäui,e mit Chromsulfat behandelt.
Der gebildete Farbstoff stellt ein braun gelbes Pulver, das sich in Wasser mit braun stichig gelber Farbe löst und Wolle aus schwefelsaurem Bade in rotstichig gelben Tönen färbt. <I>Beispiel:</I> 37 Teile des Farbstoffes aus dianotierter 1-Aininonaphtalin-4-sulfosäure und 1-Oxy- benzol-2-cai-bonsäure werden in 1500 Teilen Wasser gelöst und während einigen Stunden mit einer aus 9,1 Teilen Cr20a und 14,6 Teilen H2S04 erhaltenen Ohromsulfatlösung zum Kochen erhitzt.
Nach Beendigung der Chro- mierung wird die gebildete Chromverbindung durch Zugabe von Kochsalz aus der Lösung abgeschieden, filtriert und bei mässiger Tem peratur getrocknet.
<B> Additional patent </B> to the main patent No. 152880. Process for the production of a chromium-containing dye. It has been found that a new chromium-containing dye, which contains 1 atom of chromium for every chromable group of the dye molecule, is obtained if the dye is obtained from dianotized 1-aminonaphthalene-4-sulfonic acid and 1-oxybenzene-2-carboxylic acid, e treated with chromium sulfate.
The dye formed is a brown-yellow powder that dissolves in water with a brown-tinged yellow color and dyes wool from sulfuric acid bath in red-tinged yellow shades. <I> Example: </I> 37 parts of the dye from dianotized 1-amino naphthalene-4-sulfonic acid and 1-oxybenzene-2-cai-bonic acid are dissolved in 1500 parts of water and mixed with one of 9.1 for a few hours Parts of Cr20a and 14.6 parts of H2S04 are heated to boiling.
When the chromium plating has ended, the chromium compound formed is separated out from the solution by adding sodium chloride, filtered and dried at a moderate temperature.
