Sulfurierung organischer Produkte. Patentiert im Deutschen Reiche vom 4. Februar 1909 ab.Sulfurization of organic products. Patented in the German Empire on February 4, 1909.
Man. hat Vanadinsalze als Katalysator für Oxydationen organischer Produkte mehrfach angewandt und dadurch eine Beschleunigung des Prozesses erzielt.Man. has vanadium salts as a catalyst for the oxidation of organic products on several occasions applied and thereby achieved an acceleration of the process.
5- JEs wurde nun beobachtet, daß Vanadinsalze auch auf Sulfurierungen beschleunigend einwirken und dadurch den Sulfurierungsprozeß abkürzen. Hierdurch wird einmal ein größerer Effekt mit der gleichen Apparatur ίο erzielt und ferner erreicht, daß etwa auftretende, mit Verlust verbundene unerwünschte Reaktionen in ihrer Wirkung zurücktreten.5- It has now been observed that vanadium salts also have an accelerating effect on sulfurization and thereby the sulfurization process abbreviate. This once a greater effect is achieved with the same apparatus ίο and also achieved that any occurring, unwanted reactions associated with loss become less effective.
Beispiel.
100 g Anthrachinon mitExample.
100 g of anthraquinone with
Schwefelsäure von 60Sulfuric acid of 60
80 g rauchender Prozent 5 0» werden unter Zusatz von o.i bis 0,2 g Vanadinsulfat ι Stunde bei 1700 sulfuriert. Dabei werden 86 g Chinon in Mono- bzw. Disulfosäure umgewandelt, und zwar mit vollkommen theoretischer Ausbeute im Gegensatz zu Sulfurierung ohne Vanadinsulfatzusatz, die 8 bis 10 Stunden Zeit erfordert und dabei etwa 20 Prozent Verluste an Chinon ergibt.80 g of fuming percent 5 0 "be sulfurized with the addition of 0.2 g oi to Vanadinsulfat ι hour at 170 0th In this process, 86 g of quinone are converted into mono- or disulfonic acid, with a completely theoretical yield, in contrast to sulfurization without the addition of vanadium sulfate, which takes 8 to 10 hours and results in a loss of quinone about 20 percent.
