Additional information

Experimental data on the physicochemical properties of the organic substance chloroform (CAS No. 67-66-3) are scarce. Chloroform is a clear, colourless, volatile liquid with pleasant etheric odour. Its melting point is at -63.5 °C (The Merck Index 1976) and the boiling point is at 61 °C (The Merck Index 1976, Verschueren 2009 and Moelwyn-Hughes and Missen 1957).

The relative density of chloroform at 20 °C is 1.49 g/cm3 (Verschueren 2009).

Its vapour pressure at 20 °C is 211 hPa (Moelwyn-Hughes and Missen 1957 and Verschueren 2009).

The water solubility of chloroform at 23 °C is 8700 mg/L (Broholm and Feenstra 1993).

The surface tension of chloroform is approximately 27.1 mN/m at 20°C (HSDB 2008) and the viscosity is approximately 0.56 mPa*s (Prager 1995).

Chloroform is stable in organic solvents.

Chloroform does not have a flash-point and is non-flammable. Based on the structure of its molecule, chloroform is non-explosive and non-oxidising.
