9 Carbonyl Sulfide Uses : Facts You Should Know!

Carbonyl sulfide (COS) also known as carbon oxide sulfide and carbon oxysulfide is a colorless gas that smells like rotten eggs. Let us study briefly about some of the uses of COS.

The industrial uses of carbonyl sulfide are listed below.

  • Metal industry
  • Polymer industry
  • Synthetic industry
  • Agricultural industry
  • Biochemical industry

This article emphasizes some of the important uses of carbonyl sulfide-

Metal industry

Carbonyl sulfide is compatible with many metals such as aluminum, copper, Monel, carbon steel, stainless steel, brass.

Polymer industry

COS is used in Synthetic polymers such as PVC and Teflon that are shipped in steel cylinders as a liquefied gas

Synthetic industry

  • Carbonyl sulfide is used as an intermediate in the synthesis of organic sulfur compounds and alkyl carbonates.
  • COS is specifically used in the industrial synthesis of thio acids, sulfur trisubstituted carbinols, substituted thiazoles
  • COS is found in flavors and fragrances and used as an ingredient in substituted thiocarbamic acids.

Agricultural industry

  • COS is applied as an intermediate in the manufacture of certain herbicides.
  • COS is used in the agricultural industry as a grain fumigant.
  • One of the recent applications of carbonyl sulfide is as an agricultural fumigant as fumigation has been an excellent alternative defensive measure against pests like termites, beetles and moths, as well as mites.

Biochemical industry

  • Carbonyl sulfide is found to induce the condensation of amino acids under stimulated earth conditions.
  • COS plays a significant role in solid phase synthesis of chemical peptides.

Conclusion :

The increasing importance of carbonyl sulfide in many aspects of human life guarantees the continuing research interest in this simple yet unique molecule. The continuing role of this molecule is especially pronounced in energy sciences and in the environment.
