What are the properties of n-propanol?

Physical Properties

• Appearance: Colorless, transparent liquid
• Melting point: −126.5 °C (some sources report −127 °C)
• Boiling point: 97.4 °C (some sources report 97.1 °C)
• Flash point: 15 °C
• Density: 0.804 g/cm³ (other data list relative density 0.80, with water = 1)
• Solubility: Soluble in water, ethanol, and ether; miscible with most organic solvents such as alcohols and ethers.

Chemical Properties

• Functional group: Hydroxyl group (–OH)
• Incompatible substances: Strong oxidizers, acid anhydrides, acids, halogens
• Reaction types: As a typical alcohol, n-propanol can undergo elimination, oxidation, substitution, and esterification reactions. Under acidic conditions, it dehydrates easily to form an alkene, and further oxidation can break carbon–carbon bonds, producing small-molecule compounds.
