Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

CALIBRATION

SUBSTANCE USED FOR CALIBRATION: Water

POUR POINT (THEORY): 0 °C

POUR POINT (EXPERIMENTAL): 0 °C

MEASUREMENT (repeat determination)

POUR POINT: TEST: -3°C / -3°C

POUR POINT : AVERAGE : -3°C

Conclusions:
Average pour point: -3 °C at atmospheric pressure.
Executive summary:

The pour point of Nonan-1-ol was assessed according to ASTM D 97 -08. The pour point was -3 °C at atmospheric pressure.

Description of key information

The melting point of nonan-1-ol is -3°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-3 °C

Additional information

The melting point of -3°C was determined in a reliable study.

It is supported by a value of -5°C taken from a reliable handbook, and consistent results from another reference source.

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.
