I found some interesting stuff while doing some research and thought it might be useful. http://www.chevron.com/products/prodserv/fuels/bulletin/aviationfuel/toc.shtm http://www.chevron.com/products/prodserv/fuels/bulletin/aviationfuel/1_at_fuel_intro.shtm http://www.chevron.com/products/prodserv/fuels/bulletin/aviationfuel/4_at_fuel_comp.shtm Naphthalene (Aromatic) C10H8 n-Dodecane (n-Paraffin) C12H26 Hydrocarbon Missile Fuels ------------------- Sinclair Oil Co. MSDS- SPECIFIC GRAVITY (g/ml): 0.77-0.84 VAPOR DENSITY (air=1): 4.5 ------------------- Physical and Chemical Properties of Military Fuels - National Academies Press =================================== Toxicokinetics of Military Fuels It is not possible to fully describe the toxicokinetics of the individual volatile hydrocarbons that are present in JP-5, JP-8, and diesel fuel marine (DFM). However, toxicoldnetic data are available for the most toxic chemicals in each of the major classes of these fuels. For example, the n-paraffin group includes n-hexane, a human neurotoxicant. In the branched paraffin group, the chemical 2,2,4-trimethylpentane is thought to be responsible for the development of kidney-specific nephropathy and carcinogenicity in gasoline-exposed male rats. The aromatic group contains benzene (a human hematotoxicant and leukemogen) as well as toluene and the o-, m-, and p-xylenes. Finally, methoxyethanol, an important deicing additive in fuels, is a known developmental and reproductive toxicant. Thus, one of the major challenges in describing the behavior of the various hydrocarbons in these fuels is predicting the effect of other present hydrocarbons on the toxicokinetics of each highly toxic chemical.
