Abstract : Oxidation and condensation products of a standard jet fuel at 190-200C have been concentrated and fractionated to give materials of average molecular weight of >300 by (1) precipitation from pentane and (2) gel permeation chromatography. Heating fuel with stainless steel wool and oxygen at 200C has given insoluble deposits that can be removed only by heating in air. A deposit from a simulated fuel manifold has been analyzed. Some contemporary work on fuel stability has been reviewed and recommendations for further work toward a useful stability test are presented. (Modified author abstract)
