n-Hexadecane is generally a white solid or colorless liquid. The melting point is 18.2℃, the boiling point is 286.79, the flash point is 135℃, the ignition point is 202℃, and the density is 0.7734g/cm3. Miscible with diethyl ether, petroleum ether and chloroform, slightly soluble in hot ethanol, insoluble in water.

Production method:

1. Prepared by catalytic chlorination of 1-hexadecene.

2. N-hexadecane can be obtained by reducing hexadecane iodide with zinc powder in acidic medium.

3. To prepare chromatographically pure n-hexadecane, nitrogen can be used as the carrier gas, and the crude product is injected on a preparative gas chromatograph equipped with a squalane/white diatomite carrier stationary phase column, and then separated Collect the main peak components, then put them into glass ampoules and seal them.

4. Tobacco: FC, 56; FC, 18, 26; FC, 40.

Uses:

1. Used as phase change materials, widely used in pharmaceutical cold chain logistics, phase change energy storage buildings, and phase change microstructures for textiles Temperature control of capsules and electronic components.

2. Used in organic synthesis.

3. Used as solvent, gas chromatography reference substance and stationary solution.

4. Standard materials for measuring diesel combustion quality. The cetane number of diesel fuel is equal to the volume percentage of cetane contained in the standard fuel (a mixture of cetane and α-methylnaphthalene) when the combustion quality is the same as that of the diesel being evaluated under specified working conditions.
