Description
ι Es wurde gefunden, daß bei der bereits bekannten Einwirkung von Ammoniak auf Anthrachinon-2-sulfosäure zwecks Darstellung von 2-Aminoanthrachinon die Ausbeute wesentlich erhöht wird, wenn die bei der Reaktion entstehende schweflige Säure durch Zusatz von Bariumchlorid bzw. durch Anwendung des entsprechenden Bariumsalzes der Anthrachinon-2-sulfosäure in eine schwer lösliche Form übergeführt wird. ι It has been found that the yield is significantly increased by the action of ammonia already known anthraquinone-2-sulfonic acid for the purpose of preparation of 2-aminoanthraquinone, when the sulfurous acid formed in the reaction by the addition of barium chloride, or by applying the corresponding barium salt the anthraquinone-2-sulfonic acid is converted into a poorly soluble form.
4,i2 Teile fein gepulvertes anthrachinon-2-4, i2 parts finely powdered anthraquinone-2-
sulfosaures Natrium werden in eine Lösung von 2,36 Teilen kristallisiertem Bariumchlorid in • der 3,1 fachen Menge Wasser eingetragen und nach Zusatz von 20,5 Liter wäßrigem 25 prozentigem Ammoniak 48 Stunden auf 170 bis 177 ° bei einem Druck von 21 bis 22 Atmo-Sphären erhitzt. Nach dem Erkalten wird der Druckkesselinhalt abfiltriert und nacheinander mit Wasser, verdünnter Salzsäure und verdünnter Sodalösung-ausgekocht. An reinem, aus Chlorbenzol umkristallisiertem 2-Aminoanthrachinon werden auf diese Weise 2,19 Teile = 53,1 Prozent vom angewandten Natriumsalz oder 73,7 Prozent der Theorie erhalten.Sodium sulphate are dissolved in a solution of 2.36 parts of crystallized barium chloride in • 3.1 times the amount of water entered and after adding 20.5 liters of aqueous 25 percent ammonia to 170 to 48 hours 177 ° heated at a pressure of 21 to 22 atmospheres. After it has cooled down the pressure vessel contents are filtered off and successively with water, dilute hydrochloric acid and diluted soda solution-boiled. On pure 2-aminoanthraquinone recrystallized from chlorobenzene in this way 2.19 parts = 53.1 percent of the sodium salt used or 73.7 percent of theory received.
Arbeitet man unter den angegebenen Verhältnissen ohne Zusatz von Bariumchlorid, so beträgt die Ausbeute an 2-Aminoanthrachinon nicht mehr als 50 Prozent der Theorie.If one works under the given conditions without the addition of barium chloride, so the yield of 2-aminoanthraquinone is not more than 50 percent of theory.
Patbnt-Anspruch:Patbnt claim:
Verfahren zur Darstellung von 2-Aminoanthrachinon aus Anthrachinon-2-sulfosäure und Ammoniak, dadurch gekennzeichnet, daß man die bei der Reaktion entstehende schweflige Säure durch Überführung in das schwer lösliche Bariumsulfit von der weiteren Einwirkung auf das Anthrachinonmolekül ausschließt.Process for the preparation of 2-aminoanthraquinone from anthraquinone-2-sulfonic acid and ammonia, characterized in that the sulfurous acid formed in the reaction is converted into the poorly soluble barium sulfite from further action on the anthraquinone molecule excludes.
