Description of key information
The melting point of undecan-1-ol is 12.5°C at 1 atm pressure.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 12.5 °C
Additional information
The melting point of 12.5°C was determined in accordance with the ASTM E537-07 test method. The result is considered reliable.
It is supported by a value of 19°C taken from a reliable handbook, and various 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, melting point increases. This is because molecular weight is higher and intermolecular forces in the substance are all higher.
