Description
Arbeitsverfahren zur Herstellung von Anthrachinon und dessen Derivaten. Zur Herstellung von Anthrachinon und dessen Derivaten aus entsprechenden Ver bindungen niederer Oxydationsstufen sind zahlreiche Verfahren bekannt., die auf der Anwendung verschiedener Oxydationsmittel, z. 13. Sauerstoffgas, beruhen.
Es Wurde nun gefunden, dass man An thracen, die Anthracenderivate und die nie deren Oxydationsstufen derselben mit Sauer stoffgas wesentlich leichter in Anthrachinon und die entsprechenden Derivate verwan deln kann, wenn man bei Gegenwart von Stickstoff-Sauerstoffverbindungen arbeit:et. Die letzteren wirken als Katalyten.
Die Wirkung des Verfahrens kann durch Zugabe noch weiterer Sauerstoffüberträger unterstützt werden.
Die Ausführung des Verfahrens erfolgt zweckmässig in der .Weise, dass man die zu oxydierenden Körper in geeigneten Flüs sigkeiten löst oder suspendiert. und hierauf unter passenden Temperatur- und Druck verhältnissen Sauerstoff einleitet, während die sauerstoffhaltigen Stickstoffverbindungen vor oder während des Oxydationsprozesses zugeführt werden. Man erhält nach dem vorliegenden Arbeitsverfahren Anthrachinon und Anthrachinon-Derivate in grosser Rein heit und vorzüglicher Ausbeute.
Beispiel <I>9:</I> 100 kg Anthracen werden in einem Kes sel mit. 500--1000 kg konzentrierter Essig s iitire bei etwa ä0--90 gründlich vermischt. während man eine geringe Menge rauchen der Salpetersäure zuführt und Sauerstoff unter Druck einleitet. Die erforderliche Menge Sauerstoff wird lebhaft absorbiert und nach ungefähr 3-5 Stunden ist die Oxy dation zu Ende geführt. Das entstandene Authrachinon wird in bekannter Weise iso liert.
Beispiel <I>2:</I> 50 kg Antlracen werden in einem Kessel mit 500 kg konzentrierter Essigsäure und 100 gr Kobaltnitrat bei 30-90 gerührt, wäh rend man Sauerstoff, welchem ein geringer Prozentsatz Stickoxydgase beigemischt ist, einleitet. Die Oxydation ist gleichfalls nach einigen Stunden beendet.
In ähnlicher Weise können Derivate, wie z. B. Anthracensulfosäuren, zu den Chinon- verbindungeri oxydiert. werden.
Process for the production of anthraquinone and its derivatives. For the production of anthraquinone and its derivatives from corresponding Ver compounds of lower oxidation levels, numerous processes are known. Based on the use of various oxidants, eg. 13. Oxygen gas, based.
It has now been found that anthracene, the anthracene derivatives and the never their oxidation stages of the same with oxygen gas can be transformed into anthraquinone and the corresponding derivatives much more easily if you work in the presence of nitrogen-oxygen compounds: et. The latter act as catalytes.
The effect of the process can be supported by adding further oxygen carriers.
The method is expediently carried out in such a way that the body to be oxidized is dissolved or suspended in suitable liquids. and then introduces oxygen under suitable temperature and pressure conditions, while the oxygen-containing nitrogen compounds are supplied before or during the oxidation process. The present working process gives anthraquinone and anthraquinone derivatives in great purity and in excellent yield.
Example <I> 9: </I> 100 kg of anthracene are placed in a kettle with. 500--1000 kg of concentrated vinegar s iitire thoroughly mixed at about - 0--90. while a small amount of smoke is added to the nitric acid and oxygen is introduced under pressure. The required amount of oxygen is vigorously absorbed and after about 3-5 hours the oxidation is complete. The resulting authraquinone is isolated in a known manner.
Example <I> 2: </I> 50 kg of anthracene are stirred in a kettle with 500 kg of concentrated acetic acid and 100 g of cobalt nitrate at 30-90, while oxygen, to which a small percentage of nitrogen oxide gases is mixed, is introduced. The oxidation is also over after a few hours.
Similarly, derivatives such as. B. anthracene sulfonic acids, oxidized to the quinone compounds. will.
