Carbonyl Sulfide

COS, a higly flammable, colorless, odorless gas that liquifies at – 50.2°C and freezes at – 138.2°C. Carbonyl sulfide is readily soluble in carbon disulfide, toluene, and alcohol but somewhat less soluble in water. It is gradually decomposed by water to form CO₂ and H₂S. In the absence of moisture, carbonyl sulfide is stable. Upon heating it decomposes:

2COS = CO₂ + CS₂ and 2COS = 2CO + 2S

Carbonyl sulfide is obtained by passing a mixture of sulfur vapor and carbon monoxide through a heated tube:

S + CO = COS

It is obtained in pure form by the action of acids on ammonium thiocarbamate, CO(NH₂)(SNH₄). Carbonyl sulfide is used in the industrial production of urea.
