Dischwefelmonoxid is a chemical compound from the group of oxides of sulfur. The compound was first presented in 1933 by Peter W. Schenk, which, however, kept in touch for sulfur monoxide.

Occurrence

Dischwefelmonoxid was detected on Jupiter's moon Io.

Production and representation

96 % to 100 % pure Dischwefelmonoxid can be obtained by reaction of Thionylchloriddampf with silver sulfide at 160 ° C.

In the reaction of sulfur with oxygen or copper ( II) oxide is not a pure Dischwefelmonoxid formed.

It is also formed by the decomposition of sulfur monoxide

Or its reaction with sulfur.

Properties

Dischwefelmonoxid is a colorless gas, which reacts with water under formation of sulfur, hydrogen sulfide and sulfur dioxide. It is only in the gas phase at pressures of less than 1 mbar and a few days Stable polymerized at higher pressures, in solvents or at elevated temperatures with elimination of sulfur dioxide to yellow to orange Polyschwefeloxiden (SnO ) x. With bases and halogens the compound reacts.
