Description

Verfahren zur Herstellung von Kohlenoxysulfid und Schwefelkohlenstoff. Von den verschiedenen Bildungsmöglichkeiten des Kohlenoxysulfids hat bisher keine eine technische Anwendung gefunden; entweder waren die Ausbeuten sehr gering oder die Ausgangsstoffe nur schwierig zu beschaffen. Andererseits wird Schwefelkohlenstoff technisch ausschließlich durch Einwirkung von Schwefeldampf auf glühende Kohle erzeugt.Process for the production of carbon oxysulfide and carbon disulfide. So far none of the various ways in which carbon oxysulphide can be formed found a technical application; either the yields were very low or the raw materials are difficult to obtain. On the other hand, it becomes carbon disulfide technically produced exclusively by the action of sulfur vapor on glowing coal.

Es wurde nun gefunden, daß man Kohlenoxvsulfid und Schwefelkohlenstoff aus Kohlenoxyd und Schwefel bei Gegenwart geeigneter Kontaktsubstanzen, wie z. B. Eisen, Holzkohle, aktiver Kohle u. dgl., leicht erhalten kann, wenn man bei höheren Temperaturen, insbesondere solchen zwischen etwa 4oo bis 6oo° C arbeitet. Statt des Schwefels kann man auch Schwefel liefernde Verbindungen, wie z. B. Schwefeldioxyd, verwenden.It has now been found that carbon oxysulfide and carbon disulfide can be used from carbon oxide and sulfur in the presence of suitable contact substances, such as. B. Iron, charcoal, active charcoal and the like, can easily be obtained if one at higher Temperatures, especially those between about 400 to 600 ° C., works. Instead of the sulfur can also be sulfur-yielding compounds, such as. B. sulfur dioxide, use.

Beispiel i.Example i.

Kohlenoxyd wird über oder durch nahe auf die Verdampfungstemperatur erhitzten Schwefel geleitet und das Kohlenoxyd-Schwefeldampfgemisch der Einwirkung eines aus Eisen bzw. Schwefeleisen bestehenden, auf .450° erhitzten Katalysators ausgesetzt. Es wird dabei eine weitgehende bis völlige @"erainigung des Schwefels mit dem Kohlenoxyd zu Kohlenoxysulfid und Schwefelkohlenstoff erreicht; als Nebenprodukt entsteht Kohlendioxyd. Das erhaltene Gasgemisch hat etwa folgende Zusammensetzung: io bis 15 Volumprozent Schwefelkohlenstoff, 65 bis 7o Volumprozent Kohlenoxy sulfid, 2o Volumprozent Kohlensäure.Carbon dioxide becomes above or through close to the vaporization temperature heated sulfur passed and the carbon oxide-sulfur vapor mixture of the action a catalyst made of iron or iron sulfur and heated to .450 ° exposed. There is an extensive to complete recovery of the sulfur reached with the carbon monoxide to carbon oxysulfide and carbon disulfide; as a by-product carbon dioxide is produced. The gas mixture obtained has approximately the following composition: 10 to 15 percent by volume carbon disulfide, 65 to 7o percent by volume carbon oxy sulfide, 2o volume percent carbonic acid.

Beispiel a.Example a.

Kohlenoxyd und Schwefeldioxyd werden im Verhältnis von etwa 3 Volumen Kohlenoxyd auf i Volumen Schwefeldioxyd über auf 4.0o bis 5oo° erhitzte Holzkohle geleitet; es entstehen in guter Ausbeute Kohlenoxysulfid und Schwefelkohlenstoff. Das erhaltene Gasgemisch eist aber reicher an Kohlendioxyd als in Beispiel i.Carbon dioxide and sulfur dioxide become in the proportion of about 3 volumes Carbon dioxide to one volume of sulfur dioxide over charcoal heated to 4.0o to 500o directed; carbon oxysulfide and carbon disulfide are formed in good yield. However, the gas mixture obtained is richer in carbon dioxide than in Example i.

Das aus Kohlenoxysulfid, Schwefelkohlenstoff und Kohlendioxyd bestehende Gasgemisch kann vielfach unmittelbar verwendet werden, oder man kann es durch fraktionierte Kondensation oder mittels Adsorption an geeigneten aktiven Stoffen, z. B. mittels aktiver Kohle, ohne Schwierigkeit in seine Bestandteile zerlegen oder von Kohlendioxyd befreien.That consisting of carbon oxysulfide, carbon disulfide and carbon dioxide Gas mixture can often be used directly, or it can be fractionated Condensation or by means of adsorption on suitable active substances, e.g. B. by means of active charcoal, decomposing into its constituent parts without difficulty, or of carbon dioxide to free.
