Carbonyl Sulfide: A Review of its Chemistry and Properties



P D. Svoronos, Thomas J. Bruno


A number of years have elapsed since the last comprehensive review of the chemical properties of carbonyl sulfide (COS), with specific attention to the tendency of this fluid to undergo hydrolysis. Since that time, some important issues have arisen regarding the presence of COS in industrial product streams and the application of COS as agricultural fumigants. An example of a relatively new industrial issue is the presence of naturally occurring COS in liquefiedpetroleum gas (LPG). It is believed that the hydrolysis of this COS is the cause of corrosion and compliance testing failures in the LPG industry. This issue,as well as many other chemical and physical property issues in industry, make this an appropriate time to revisit the chemistry of this interesting fluid, with special attention to recent observations.
