Physical properties of phenanthrene

Phenanthrene, a polycyclic aromatic hydrocarbon, possesses several physical properties:

  1. Appearance: Phenanthrene typically appears as colorless to pale yellow crystals or a white powder.
  2. Odor: It has a distinctive aromatic odor.
  3. Melting Point: The melting point of phenanthrene is around 97.5°C (207.5°F).
  4. Boiling Point: Phenanthrene has a boiling point of approximately 340°C (644°F).
  5. Solubility: It is sparingly soluble in water but soluble in organic solvents such as ethanol, ether, benzene, and chloroform.
  6. Density: The density of phenanthrene is approximately 1.178 g/cm³.
  7. Molecular Weight: The molecular weight of phenanthrene is 178.23 g/mol.
  8. Flammability: Phenanthrene is combustible and can burn with a sooty flame when exposed to a sufficient heat source.

These physical properties contribute to the characterization and handling of phenanthrene in various industrial, research, and analytical settings.
