Among them the liquid alkanes (undecane dodecane tridecane tetradecane pentadecane hexadecane heptadecane etc.) are widely used in fuel oils and as anti-corrosive agents in lubricating oils and solid alkanes (octadecane nonadecane eicosane heneicosane tricosane tetracosane heptacosane octacosane etc.) find their use in paraffin waxes of different kinds.
Acetate, methyleugenol, heptadecane, pentadecane, docosanenerol, disiloxane, octadecane, and pentacosane.
Hydrocarbons, including alkanes and alkenes (e.g., tetradecene, pentadecane, hexadecane, and octadecene), were abundant in three (Okayama, Tokushima, and Ehime) of the four samples (Figure 3).
