Description

Verfahren zur Herstellung von Anthrachinon oder seinen Derivaten. Im Patent 4o62¢5 ist ein Verfahren zur Herstellung von Anthrachinon und seinen Derivaten beschrieben, welches dadurch gekennzeichnet ist, daß die zu oxydierenden Verbindungen in Essigsäure als Lösungs-oder Suspensionsmittel mit Sauerstoff oder sauerstoffhaltigen Ga-en oder Dämpfen in Gegenwart geringer Mengen sauerstoffhaltiger Verbindungen des Stickstoffs und gegebenenfalls weiterer Sauerstoffüberträger oder Katalysatoren behandelt werden. Nach dem Zusatzpatent 4o6777 werden an Stelle von Essigsäure andere saure Lösungs- oder Suspensionsmittel, z. B. Propionsäure, oder aber gleichzeitig mit den sauren Lösungsmitteln an und für sich nicht geeignete Mittel, wie Wasser, Nitrobenzol, Dichlorbenzol, verwendet.Process for the preparation of anthraquinone or its derivatives. Patent 4062 [5] describes a process for the preparation of anthraquinone and its derivatives described, which is characterized in that the compounds to be oxidized in acetic acid as a solvent or suspending agent with oxygen or oxygen-containing Ga-en or vapors in the presence of small amounts of oxygen-containing compounds of nitrogen and optionally other oxygen carriers or catalysts be treated. According to the additional patent 4o6777, instead of acetic acid, other acidic solvents or suspending agents, e.g. B. propionic acid, or at the same time with the acidic solvents in and of itself unsuitable means, such as water, Nitrobenzene, dichlorobenzene, is used.

Es wurde nun gefunden, daß der Zusatz der sauerstoffhaltigen Verbindungen des Stickstoffs sich wesentlich vereinfachen läßt dadurch, daß man der sauren Lösung der zu oxydierenden Stoffe geringe Mengen in Wasser gelöste Nitrite während des Einleitens von Sauerstoff zusetzt. Dabei wird außerdem noch ein wesentlicher Vorteil erreicht, insofern, als das als Katalysator wirkende Nitrit, z. B. Natriumnitrit, durch die Essigsäure, welche als Lösungs- oder Suspensionsmittel benutzt wird, in Natriumacetat übergeführt und die schädliche Wirkung der während. des Verfahrens etwa entstehenden Salpetersäure durch das entstandene Natriumacetat unschädlich gemacht wird, indem sich Natriumnitrat bildet.It has now been found that the addition of the oxygen-containing compounds the nitrogen can be considerably simplified by adding the acidic solution of the substances to be oxidized, small amounts of nitrites dissolved in water during the Introducing oxygen clogs. There is also a significant advantage here achieved, insofar as the nitrite acting as a catalyst, e.g. B. sodium nitrite, by acetic acid, which is used as a solvent or suspending agent, in Sodium acetate transferred and the harmful effects of during. of the procedure any nitric acid formed harmless by the sodium acetate formed is made by the formation of sodium nitrate.

Man kann an Stelle des Nitrits auch Salpetersäure oder Stickoxyde in Gasform als Sauerstoffüberträger zu dem Lösungs- oder Suspensionsmittel während der Behandlung mit Sauerstoff usw. zugeben. In diesem Falle ist es jedoch gemäß der Erfindung erforderlich, so viel Natriumacetat oder ähnliche leichtlösliche, salpetersäurebindende Mittel dem Reaktionsgemisch zuzugeben, daß die für sich oder mit den Stickoxyden zugeführte Salpetersäure oder die während der Reaktion gebildete Salpetersäure gebunden wird.Instead of the nitrite, nitric acid or nitrogen oxides can also be used in gaseous form as an oxygen carrier to the solvent or suspending agent during add to treatment with oxygen, etc. In this case, however, it is appropriate the invention required as much sodium acetate or similar easily soluble, to add nitric acid binding agents to the reaction mixture that the for themselves or nitric acid added with the nitrogen oxides or that formed during the reaction Nitric acid is bound.

Bei beiden Arbeitsweisen wird mithin die zugegebene oder ,aus den Stickoxyden etwa entstehende Salpetersäure unschädlich gemacht, was natürlich für den Reinheitsgrad des Endproduktes von maßgebendem Einfluß ist.In both working methods, the added or, from the Nitric oxides any nitric acid formed harmless, which of course for the degree of purity of the end product is of decisive influence.

Beispiele: i. i oo kg g iprozentiges Anthracen werden in einem geschlossenen Gefäß mit 5oo kg Essigsäure auf etwa go° unter Rühren erhitzt, und während man ungefähr i bis 5 kg Natriumnitrit in wäßriger Lösung zugibt, unter Einleiten von Sauerstoff oxydiert. Nachdem die Absorption des Sauerstoffs aufgehört hat, läßt man erkalten und saugt man das entstandene Anthrachinon ab. Die Ausbeute beträgt etwa 95 Prozent, der Schmelzpunkt liegt bei 28i°, das Anthrachinan' ist ungefähr 98prozentig.Examples: i. i oo kg g ip percent anthracene are in a closed Vessel with 500 kg of acetic acid heated to about go ° with stirring, and while about I add up to 5 kg of sodium nitrite in aqueous solution, while passing in oxygen oxidized. After the absorption of oxygen has ceased, it is allowed to cool and one sucks the resulting Anthraquinone off. The yield is about 95 percent, the melting point is 28 °, the anthraquinane is about 98 percent.

2. i oo-kg -85prozentiges Anthracen werden in einem geschlossenen Gefäß mit sookg Essigsäure auf 9o° unter Rühren erhitzt, worauf man, während man etwa i bis. 5 1 rauchende Salpetersäure allmählich zugibt, Sauerstoff einleitet. Zur Bindung der Salpetersäure gibt man etwa io bis, 2okg Natriumacetat zu. Die Ausbeute beträgt ungefähr 95 Prozent, der Schmelzpunkt liegt bei 279 bis 28o°, das Anthrachinon ist etwa 97prozentig.2. i oo-kg -85% anthracene are in a closed Vessel with soaked acetic acid heated to 90 ° with stirring, whereupon, while one about i to. 5 gradually adding 1 fuming nitric acid, introducing oxygen. About 10 to 10 g of sodium acetate are added to bind the nitric acid. The yield is about 95 percent, the melting point is 279 to 28o °, the anthraquinone is about 97 percent.

3. iookg 95prozentiges Anthracen werden in ejnem geschlossenen Gefäß mit Zoo kg Propionsäure, Zoo kg Benzol unter Rühren erhitzt. Während man i bis 5 kg Natrimnitrit in wäßriger Lösung zugibt, leitet man in das Gemisch Sauerstoff ein. Die weitere Behandlung erfolgt wie in Beispiel i. Die Aasbeute und Reinheit des Anthrachinons stimmen mit demjenigen in Beispiel i überein.3. Cooked 95 percent anthracene in a closed vessel with zoo kg propionic acid, zoo kg benzene, while stirring. While adding 1 to 5 kg of sodium nitrite in aqueous solution, oxygen is passed into the mixture. The further treatment takes place as in example i. The carcass yield and purity of the anthraquinone are the same as in Example i.
