Description of key information

The pour point of tetradecan-1-ol is 39°C at 1013 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
39 °C

Additional information

A measured pour point value of 39°C at 1013 hPa was determined in accordance with ASTM-D97 test method. The result is considered to be reliable and is selected as key study.

It is supported by melting point value in the range 39-40°C taken from a reliable handbook which has been subject to peer review and various consistent results from other secondary sources of non assignable reliability.

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.
