2.1 Physico-chemical properties

At room temperature, benzene is a colorless liquid with a strong aromatic odor, less dense than water, in which it is practically insoluble (0.180 g per 100 g at 25°C). It is miscible with most organic solvents and forms azeotropic mixtures with water, certain alcohols and hydrocarbons.

Molecular mass: 78.11 g/mol

Melting temperature: 5.5 °C

Boiling temperature: 80.1°C

Vapour pressure at 26.1°C: 13.3 kPa

Density at 20°C: 0.879 g/cm 3 .

Vapour density: 2.70

Critical temperature: 288.5 °C
