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.

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.
