Description of key information
The pour point of docosan-1-ol is 71°C at 1013 hPa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 71 °C
Additional information
A measured pour point value of 71°C at 1013 hPa was determined in accordance with OECD 102 Test Guideline.The result is considered to be reliable.
It is supported by a value of 72.5°C taken from a reliable handbook.
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.
