B. Beaver et al., MODEL STUDIES DIRECTED AT THE DEVELOPMENT OF NEW THERMAL OXIDATIVE STABILITY ENHANCING ADDITIVES FOR FUTURE JET FUELS, Energy & fuels, 11(2), 1997, pp. 396-401
Thermal stressing of a Jet A fuel containing triphenylphosphine (TPP)
as an additive results in a significant enhancement in thermal oxidati
ve stability. Efforts to elucidate the mechanism(s) responsible for th
e observed thermal oxidative stability enhancement are reported, Data
presented for the reaction of TPP with molecular oxygen show two pathw
ays to be important. In particular, in nonpolar solvents and in the pr
esence of BHT, the data. are consistent with TPP playing an oxygen sca
venging role via operation of an electron-transfer-initiated-oxygenati
on chain mechanism. The significances of these findings to the potenti
al development of a new generation of thermal oxidative stability enha
ncing additives is discussed.
