Executive summary:

The pour point of Decan-1 -ol was assessed according to ASTM-D97. The pour point was 6 °C at atmospheric pressure.

Description of key information

The melting point of decan-1-ol is 6°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
6 °C

Additional information

The melting point of 6°C was determined in a reliable study.

It is supported by a value of 6.4°C taken from a reliable handbook, and various consistent results from other reference sources. An alternative value of ca. -0.1°C was measured in a reliable study using a less highly purified sample.

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

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