Verfahren zur Darstellung von Leukoverbindungen der Gallocyaninreihe.
EMI1.1
aus Farbstoffen der Gallocyanroihe beschrieben, die man durch Erhitzen dieser Farbstoffe mit Glycerin erhält.
Es wurde nun gefunden, dass die Ausführung dieser Reaktion nicht an die Anwendung von Glycerin gebunden ist, sondern durch einfaches Erhitzen der Lösungen oder Sus- ponsionen der Farbstoffe auf Temperaturen über 1000 angeführt werden kann. Als Lösungsund Suspensionsmittel können sowohl Wasser, als auch organische Körper Verwendung finden. Auf den Verlauf der Reaktion ist es ohne Einfluss, ob die Farbstoffe in Form ihrer
EMI1.2
mit 50 kg Alkohol unter Rühren im autoklaven drei Stunden auf 1400 erhitzt. Man destilliert den Alkohol im Vakuum ab und löst den Rückstand im Wasser zu einer direkt verwendbaren Lösung.
Beispiel 2.
20 kg Gallaminblau (Farbstoff aus Nitrosodimethylanilin und Gallaminsäure) werden mit 50/)' Wasser im Autoklaven sieben Stunden unter Rühren auf 1250 erhitzt ; die er-
EMI1.3
Beispiel 3.
10 kg Cölestinblaubase werden mit 30 Wasser angerührt und im Autoklaven drei Stunden auf 140 erhitzt. Die Lösung ist dann hellg3lb gefärbt und die Leukoverbindung des Farbstoffes zum grössten Teil ausgeschieden ; man bringt sie durch Zugabe von 3'7 kg Salzsäure von 19 Hc in Lösung, die direkt zum Drucken und Färben verwendbar sind.
Die Nuancen der Drucke und Färbungen sind erheblich blauer als die der Ausgangsmaterialien.

Process for the preparation of leuco compounds of the gallocyanin series.
EMI1.1
described from dyes of the Gallocyanroihe which are obtained by heating these dyes with glycerol.
It has now been found that the execution of this reaction is not tied to the use of glycerol, but can be carried out by simply heating the solutions or suspensions of the dyes to temperatures above 1000. Both water and organic bodies can be used as solvents and suspending agents. It has no influence on the course of the reaction whether the dyes are in their form
EMI1.2
heated to 1400 for three hours in an autoclave with 50 kg of alcohol while stirring. The alcohol is distilled off in vacuo and the residue is dissolved in water to form a directly usable solution.
Example 2.
20 kg of gallamine blue (dye made from nitrosodimethylaniline and gallamic acid) are heated with 50% water in an autoclave for seven hours with stirring to 1250; which he-
EMI1.3
Example 3.
10 kg of celestine blue base are mixed with water and heated to 140 for three hours in an autoclave. The solution is then colored light yellow and most of the leuco compound of the dye is excreted; they are brought into solution by adding 3'7 kg of hydrochloric acid of 19 Hc, which can be used directly for printing and dyeing.
The nuances of the prints and colors are considerably bluer than those of the raw materials.
