OCTADECANE

1.Introduction
n-Octadecane is a pure, straight-chain alkane derived from renewable plant resources, characterized by high purity, high enthalpy value, and stable chemical properties. It finds extensive applications in functional temperature-regulating textiles, building energy efficiency, and cold chain transportation. Beyond its use as a phase change material, n-octadecane serves as an environmentally friendly, renewable, pure plant-derived, natural, non-polluting non-polar organic solvent—an excellent alternative to mineral oils.

2.Biological Activity
Octadecane is an alkane that stores thermal energy as a phase change material at ambient temperatures.

3Applications
Can be used as a standard substance for chromatographic analysis.

4.Applications
Gas chromatography stationary phase (maximum operating temperature 60°C, solvents: petroleum ether, toluene); separation and analysis standard.
