Safety Assessment - Oxygen balance

 

The oxygen balance (OB) of an organic compound is a guide to its propensity to decompose, deflagrate or detonate using only the oxygen contained in the molecule.

It has been defined by Lothrop and Handrick(1949) and will be calculated as:

OB = -1600 (2x + y/2 - z)/M

Where for an organic compound CxHyOz + (x+y/4 - z/2) O2 ⇒ x CO2 + y/2 H2O and M is the molecular weight.

It should be pointed that the use of this tool implies the presence of oxidising groups (functional groups) like nitro, nitrate, chlorate, peroxy in the molecule.  Using the oxygen balance without this additional information often will lead in wrong (nonsensical) results.
