Description of key information

The boiling point of dodecan-1-ol is 229°C at 1013 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

229 °C

Additional information

The boiling point of 229°C at 1013 hPa was determined in a reliable study according to ASTM-D1120.

It is supported by a value of 259°C taken from a reliable handbook, and consistent results from other reference sources.

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

As chain length increases, boiling point increases. This is because molecular weight is higher and intermolecular forces in the substance are all higher. There is some evidence for decomposition before boiling for the longest chain alcohols in this group.
