Description
Zusatzpatent zum Hauptpatent Nr. 114283. Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man diejenige p-Tolyl- barbitursäure, welche aus p-Tolylharnstoff und Malonester erhalten wird, mit dianotierter 4-Chlor-2-amino-l-phenol-6-sulfosäure kuppelt und das so erhaltene Produkt mit Fluor chrom behandelt. Der neue Farbstoff bildet ein oranges Pulver, löst sich in verdünnter Sodalösung mit oranger Farbe und erzeugt auf Wolle, aus saurem Bade gefärbt, echte rotorange Töne.
<I>Beispiel:</I> 224 Teile 4-Chlor-2-amino-l-phenol-6- sulfosäure werden wie üblich dianotiert und in ein Gemisch von 228 Teilen p-Tolyl- barbitursäure, 133 Teilen 30o/oiger Natron lauge, 170 Teilen Soda und 1500 Teilen Wasser eingetragen. Die Kupplung setzt so fort ein; zu ihrer Vervollständigung rührt man noch einige Zeit. Der gebildete Farb stoff wird dann filtriert und getrocknet. 46,3 Teile dieses Farbstoffes werden in 650 Teilen kochendem Wasser gelöst und mit einer Fluorchromlösung entsprechend 15,2 Teilen Crs0a versetzt.
Man kocht mehrere Stunden am Rückflusskühler, dampft teilweise ein und gewinnt die neue Chromverbindung durch Filtrieren, gegebenenfalls unter vor herigem Aussalzen.
Additional patent to the main patent No. 114283. Process for the production of a new dye. It has been found that a new dye is obtained if that p-tolylbarbituric acid, which is obtained from p-tolylurea and malonic ester, is coupled with dianotized 4-chloro-2-amino-1-phenol-6-sulfonic acid and that thus obtained product treated with fluorine chromium. The new dye forms an orange powder, dissolves in a dilute soda solution with an orange color and produces real red-orange tones on wool dyed from an acid bath.
<I> Example: </I> 224 parts of 4-chloro-2-amino-1-phenol-6-sulfonic acid are dianotized as usual and mixed with 228 parts of p-tolylbarbituric acid and 133 parts of 30% sodium hydroxide solution , 170 parts of soda and 1500 parts of water entered. The clutch continues immediately; stir for a while to complete them. The color formed is then filtered and dried. 46.3 parts of this dye are dissolved in 650 parts of boiling water, and a fluorochrome solution corresponding to 15.2 parts of Crs0a is added.
The mixture is boiled for several hours on the reflux condenser, partially evaporated and the new chromium compound is recovered by filtration, if necessary with salting out beforehand.
