Jet fuels are aviation fuels used mainly by the United States and other North Atlantic Treaty Organization (NATO) nations for military establishments. Other fuels called Jet A and Jet A-1 are closely related fuels used by commercial airlines. JP are a complex mixture of primarily aliphatic (but also aromatic) hydrocarbons, derived from crude oil and/or kerosene by refining and adding various other additives such as fuel icing inhibitors, antioxidants, corrosion inhibitors, metal deactivators, and static dissipaters. Gas chromatographic analysis of JP-8, the most recent JP, indicates that it is made up of complex mixture of 9 to 17 different hydrocarbons, including thousands of isomers and three to six performance additives. They are generally colorless liquids and smell like kerosene. [Pg.1469]

Following previous paper chromatographic studies on aromatic acids in biological fluids (B25, B26, B31, B32, B33, D2, D19, L4, L5), Armstrong et al. (A14) have described a method for the systematic paper chromatographic analysis of phenolic acids in urine. [Pg.60]

Eisen and Ivanov [54] converted hydrocarbons of various types in a stream of hydrogen on a 0.5% palladium on silica gel catalyst. For carrying out reaction chromatographic analysis of hydrocarbon mixtures, optimum temperatures for the hydrogenation of aromatic hydrocarbons are 315—325°C. Simultaneously at the specified temperatures hydrogenation of olefins, diolefins, cyclopentenes, etc., occurs. Conversions of the hydrocarbons are presented in Table 4.1. [Pg.143]

It is well known that polycyclic aromatic hydrocarbons (PAHs) can be solubilized in aqueous solutions by micelle forming surfactants. As pointed out in our previous paper, these aqueous micellar conditions can be utilized in generating PAH-specific light emissions by electrochemical means at the rotating oxide-covered aluminum electrode. Because the aqueous micellar solutions are also well suited for chromatographic analysis of PAHs, the analytical feasibility experiments of the flow detector were carried out by utilizing the PAH-induced electroluminescence with Brij-35 and 9,10-diphenylanthracene (9,10-DPA) as the...
