Fuels for future jet engines need to be stable at very high combustion temperatures. Oxygen scavengers confer oxidative and pyrolytic stability on jet fuels, thus preventing deposit formation on engine surfaces and prolonging engine life. This dissertation examines the design, synthesis and evaluation of various phosphines for potential use as anti-oxidant additives in future jet fuels.
Steric and electronic factors were considered in the design of the phosphines. Target phosphines were synthesized. Evaluation techniques such as, chemical kinetics and phosphorus NMR, were used to specifically examine the effectiveness of these phosphines as oxygen-scavengers. Co-relations between data obtained were studied to identify traits requisite in an ideal jet-fuel additive. Phosphine cone angles and tubing-bomb studies were also utilized to complete the study.
We have developed a methodology that can design, synthesize and evaluate phosphines for their anti-oxidant properties. We have further used these techniques to design and synthesize phosphines and test them in simulated jet engine conditions to determine their real-life efficaciousness.
