Abstract:
Virtually nothing is known about the high temperature
chemistry of phosphorus in a flame environment.
Phosphorus compounds are known flame retardants though
the mechanistic evidence is empirically based. In the
present study, high pressure sampling mass spectrometry
and optical spectroscopic methods have been applied to
the molecular characterization of P-containing flames.
The key process controlling flame inhibition and
enhancement is identified as: HPO2 + H H2O + PO. New
thermodynamic data are presented for NaPO2 which are
present in Li/Na-containing flames.
