Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
The oxygen balance is calculated from the empirical formula of a compound in percentage of oxygen required for complete conversion
of carbon to carbon dioxide, hydrogen to water, and metal to metal oxide.
When using oxygen balance to predict properties of one explosive relative to another, it is to be expected that one with an oxygen
balance closer to zero will be potentially explosive; however, many exceptions to this rule do exist. Consideration of potentially
explosive groups therefore also needs to be undertaken.
GLP compliance:
no

Any other information on results incl. tables

Based on structural group evaluation, the substance is not potentially explosive.

Oxygen Balance (OB) Calculator:

OB% = -1600 x (2X + (Y/2) + M-Z) / Mol.wt of substance avec X = number of atoms of carbon, Y = number of atoms of hydrogen, Z = number of atoms of oxygen, and M = number of atoms of metal (metallic oxide produced).

Substance Molecular Weight = 169.2256

Oxygen Balance (%) = -278.92

Potentially Explosive based on OB (< - 200%)? NO
