- Type of method:
- pour point
- Key result
- Melting / freezing pt.:
- -13.5 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- Average pour point of -13.5°C at atmospheric pressure was determined for the substance using a relevant test method. The result is considered to be reliable.
- Executive summary:
The pour point of octan-1-ol was assessed according to ASTM-D97. The pour point was - 13.5°C at atmospheric pressure.
Reference
Measurement (repeat determination)
Pour Point in °C: -15 / -12
Description of key information
The pour point of octan-1-ol is -13.5°C at 1013 hPa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -13.5 °C
Additional information
A measured pour point value of -13.5°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 values in the range ca. -15 to -17°C taken from reliable handbook sources, and various consistent results from other secondary sources.
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.
