die Anbeute, sowie die Reinheit der Produkte gesteigert. Entgegen den Erfahrungen bei der Alkali8chmelzc tritt hier bei Gegenwart der genannten Oxydationsmittel kein weiteres Hydroxyl in das Anthrachinon-Molekül ein.
Beispiel : 100 Teile technisches, leicht lösliches Sulfosalzgemenge (Beispiel 2 des französischen Patentes Nr. 332709) werden in 400 Teilen heissem Wasser gelöst, in der Lösung 100 Teile Kalk gelöscht, darauf 30 Teile Salpeter und 200 Teile 20%ige Chlorkalziumösung zu gegeben und das Ganze im Autoklaven 10 Stunden unter Rühren auf etwa 200"erhitzt.

mit Salzsäure angesäuerten wässerigen Lösung in Form von feinen, verfilzten, orangefarbenen Nadeln erhalten. Die heisse 5prozentige Lösung dieses Salzes gibt auf Zusatz von Chlorbarium beim Erkalten fast quantitative Ausscheidung von hell orangefarbenen Nadeln des Bariumsalzes. Das Kalziumsalz ist. bedeutend löslicher als das Bariumsalz und stellt feine orangefarbene Nadeln dar.
Tonerdesulfat, Bleiazetat, Chromalaun geben Fällungen erst beim längeren Stehen. Kupfersulfat erzeugt dagegen eine sofortige braunrote Ausscheidung. Die neue Oxysulfosäure stellt einen Beizenfarbstoff dar und färbt vorchromierte Wolle violettrot. Die Verbindung soll ausserdem als Ausgangsmaterial zur Darstellung von anderen neuen Farbstofien dienen.
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von < x-ss-Oxyanthrachinonen bezw. Anthrachinon- < x-ss-oxy- sulfosäuren unter Verwendung von Anthrachinon-α-ss-sulfosäuren durch Erhitzen mit Erd- alkauhydroxyden unter Druck in wässeriger Lösung, dadurch gekennzeichnet, dass man das Erhitzen unter Zusatz von Oxydationsmitteln vornimmt.

the yield and the purity of the products increased. Contrary to the experience with alkali melting, no further hydroxyl enters the anthraquinone molecule in the presence of the oxidizing agents mentioned.
Example: 100 parts of technical, easily soluble sulphonic salt mixture (example 2 of French patent no. 332709) are dissolved in 400 parts of hot water, 100 parts of lime are slaked in the solution, 30 parts of saltpeter and 200 parts of 20% calcium chloride solution are then added and that The whole thing is heated to about 200 "in the autoclave for 10 hours while stirring. After

aqueous solution acidified with hydrochloric acid in the form of fine, matted, orange-colored needles. The hot 5 percent solution of this salt gives, when chlorinated barium is added, almost quantitative excretion of light orange needles of the barium salt when it cools. The calcium salt is. Significantly more soluble than the barium salt and shows fine orange needles.
Alumina sulphate, lead acetate and chrome alum give precipitations only when standing for a long time. Copper sulfate, on the other hand, produces an immediate brownish-red excretion. The new oxysulfonic acid is a stain dye and dyes pre-chromed wool purple-red. The compound should also serve as a starting material for the preparation of other new dyes.
PATENT CLAIMS:
1. Process for the preparation of <x-ss-oxyanthraquinones respectively. Anthraquinone <x-ß-oxysulfonic acids using anthraquinone-α-ß-sulfonic acids by heating with alkaline earth hydroxides under pressure in an aqueous solution, characterized in that the heating is carried out with the addition of oxidizing agents.
