The probes used were n-pentane, n-hexane, n-heptane, and n-octane, all reagents were obtained in the higher purity grade possibly and directly used as received without further purification.
The other reagents, Sn[(Oct).sub.2], tetrabutyl titanate (TBT), dimethyl sulfoxide-[d.sub.6] (DMSO-[d.sub.6]), monobutyltin oxide (MBTO), n-octane, methylbenzene, and diethylene glycol, purchasing from Aladdin Reagent Co., Ltd., were used without further purification.
[41] developed a detailed chemical kinetic model to describe the pyrolysis and oxidation of nine n-alkanes, from n-octane to n-hexadecane.
As can be seen from the analytical results, the concentration of M-hexane, M-heptane, n-octane, and n-nonane increased dramatically.
By doing so the following molecules were derived: octanoic acid ([CH.sub.3]([CH.sub.2])6COOH), 1-octanal ([CH.sub.3][([CH.sub.2]).sub.6]CHO), 2-octanone ([CH.sub.3][([CH.sub.2]).sub.5]CO[CH.sub.3]) and n-octane ([CH.sub.3][([CH.sub.2]).sub.6][CH.sub.3]).
It was shown that n-octane in general allows a better degree of mixing compared to the C8 oxygenated fuels, but this influence is overcome by the oxygen molecular content.

On the second analytical path the heavier components are grouped into hexanes, heptanes and octanes, with the components larger than n-octane back-flushed to provide a C9+ grouped component value.
To the best of our knowledge, the properties of the binary mixtures of n-octane, n-decane, n-dodecane, and n-tetradecane with octan-2-ol have not been reported earlier.
Yi and Cai [8] used perfluoroalkylated pyridine as a catalyst; benzaldehyde was slowly added into a mixture of malononitrile, n-octane and the catalyst and was stirred for 1.5 hours at 80[degrees]C.
The measurement results of water contact angles and the solvent absorptions in water and n-octane for cured films showed that the water and the oil repellency for FSiPUA had been improved significantly with a suitable content of fluorine and siloxane.
The chromatographic grade molecular probes used in this study, including ethyl alcohol (C2), 1-propyl alcohol (C3), 1-butyl alcohol (C4), n-hexane (C6), n-heptane (C7), and n-octane (C8), were obtained from Merck Chemical Co.
