Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Test procedure in accordance with national standard methods (ASTM) without GLP.
according to guideline
other: ASTM-D97

Type of method:
pour point
Key result
Melting / freezing pt.:
-13.5 °C
Atm. press.:
ca. 1 atm

Measurement (repeat determination)

Pour Point in °C: -15 / -12

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.

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.
