Description

Verfahren zum Herstellen von Lösungen von Azetylen und Schwefeldioxyd für Aufbewahrungs-, Lagerungs- und Transportzwecke Die Erfindung hat ein Verfahren zum Herstellen von Lösungen von Azetylen, Schwefeldioxyd und anderen Gasen zum Zweck der Aufbewahrung, der Lagerung und des Transportes dieser Gase zum Gegenstand.Process for the preparation of solutions of acetylene and sulfur dioxide for storage, storage and transportation purposes. The invention has a method for preparing solutions of acetylene, sulfur dioxide and other gases for the purpose the keeping, storage and transport of these gases is the subject.

Die Erfindung ist dadurch gekennzeichnet, daß das aufzubewahrende oder zu transportierende Gas mit Dimethylsulfoxydoder mit einem damit imprägnierten, porösen Material in Berührung gebracht wird.The invention is characterized in that the to be kept or gas to be transported with dimethyl sulfoxide or with a gas impregnated therewith, porous material is brought into contact.

Dimethylsulfoxyd wird beispielsweise hergestellt durch Oxydieren von Dimethylsulfid, einem Nebenerzeugnis der Sulfat-Pulp-Industrie, die in Handbüchern über das Sulfatverfahren zum Zweck der Pulpherstellung beschrieben ist. Es wurde nun gefunden, daß dieses Dimethylsulfoxy d die überraschende Eigenschaft besitzt, große Mengen von verschiedenen Gasen in Lösung aufnehmen zu können. So ist die Löslichkeit von Azetylen in Dimethylsulfoxyd größer als in Azeton. Darüber hinaus bietet Dimethylsulfoxyd. im Vergleich mit Azeton, den Vorteil, daß es wegen seines verhältnismäßig hohen Siedepunktes weniger flüchtig ist, so daß also Verluste durch Verdampfen der Flüssigkeit geringer sind und die technische Handhabung vereinfacht wird. Auch kann Dimethylsulfoxyd in Mischung mit Azeton oder mit anderen an sich bekanntenLösungsmitteln für Gase verwendet werden.Dimethyl sulfoxide is produced, for example, by oxidizing Dimethyl sulfide, a by-product of the sulfate pulp industry, used in manuals on the sulphate process for the purpose of pulp manufacture is described. It was now found that this dimethylsulfoxy d has the surprising property to be able to absorb large amounts of different gases in solution. Such is the solubility of acetylene is greater in dimethyl sulfoxide than in acetone. In addition, offers dimethyl sulfoxide. compared with acetone, the advantage that it is because of its relatively high Boiling point is less volatile, so that losses due to evaporation of the liquid are lower and the technical handling is simplified. Dimethyl sulfoxide can also be used as a mixture with acetone or with other known solvents for gases be used.

Dimethylsulfoxyd ist auch ein Lösungsmittel für Schwefeldioxyd und eine Reihe anderer Gase.Dimethyl sulfoxide is also a solvent for sulfur dioxide and a number of other gases.
