Pentadecane, also known as n-pentadecane, is a colorless liquid with a chemical formula of C15H32. The following is a detailed introduction to pentadecane:

I. Physical properties

Melting point: 8.5~10

Boiling point: 268 (there may be slight differences from different sources, such as the boiling point provided by Gaide Chemical Network is 270)

Flash point: 132.22

Refractive index: 1.4332

Density: 0.769g/mL (some data show 0.773g/mL, which may be due to slight differences caused by different measurement conditions or accuracy)

II. Solubility

Pentadecane is insoluble in water, methanol, and ethanol, but soluble in organic solvents such as n-hexane, acetone and ether.

3. Existence and preparation

Pentadecane exists in petroleum and can be distilled from normal alkanes obtained by straight-run refining and diesel separation by adsorption. In addition, it can also be prepared by chemical synthesis, such as synthesizing normal pentadecane through a specific chemical reaction route.

4. Uses

Organic synthesis: Pentadecane has important applications in organic synthesis.

Pentadecane is a colorless liquid with unique physical and chemical properties. Its relative density is 0.769, its melting point is between 8.5 and 10°C, and its boiling point reaches 268°C. The refractive index reaches 1.4332, showing the specific degree of bending when its light passes through. In addition, the flash point of pentadecane is 132.22°C, indicating that it will evaporate rapidly when the temperature exceeds this value. Interestingly, pentadecane is insoluble in water, but soluble in organic solvents such as n-hexane, acetone and ether, showing its potential application in the field of organic synthesis. It is worth noting that pentadecane is widely present in petroleum and can be distilled from normal alkanes obtained by straight-run refining or diesel separation by adsorption, providing valuable resources for the petrochemical industry.
