Description of key information

The melting point of dodecan-1-ol is 24°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
24 °C

Additional information

A measured pour point value of 24°C at 1013 hPa was determined in accordance with ASTM-D97 test method. The result is considered to be reliable.

It is supported by values of ca. 23 - 26°C taken from reliable handbooks.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

As the chain length increases, melting point increases. This is because molecular weight is higher and intermolecular forces in the substance are all higher.
