Abstract

Improved thermal degradation properties (an indication of improved flame-retardant properties) were observed when southern pine was reacted with either diethylchlorophosphate (DECP) or phenylphosphonic dichloride (PPDC). These two compounds may prove useful as flame retardants for wood. Thermal degradation was evaluated by thermogravimetric methods; the values were reduced slightly by extraction of the specimens with toluene or ethanol and water. When pyrolyzed in nitrogen, specimens of the reacted wood, extracted or unextracted, showed maximum rates of pyrolysis at lower temperatures and produced more char than control specimens.
