Type of method:
Key result
Atm. press.:
1 010.8 mBar
Decomp. temp.:
392 °C
Remarks on result:
other: Fog at 392°C.


barometric pressure:1010.8 mBar

Decomposition at:392°C

remarks of results:white fog at 392°C

The substance was observed to undrgoes thermal decomposition from 392°C using a relevant test method. The result is considered to be reliable.
Executive summary:

The boiling point of docosan-1 -ol was tested according to ASTM-D1120 Standard Test Method for Boiling Point of Engine Coolants. There was no boiling point detected, because there was an decomposition at 392°C.

Description of key information

A commercial sample of docosan-1-ol was found to decompose without boiling at a temperature of 392°C and 1013 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
392 °C

Additional information

The substance was observed to undergoes thermal decomposition at 392°C at 1013 hPa in accordance with ASTM D1120. The result is considered to be reliable.

This is supported by a boiling point of 180°C at 0.22 hPa which was reported for the substance in a reliable handbook.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

As chain length increases, boiling point increases. This is because molecular weight is higher and intermolecular forces in the substance are all higher. There is some evidence for decomposition before boiling for the longest chain alcohols in this group.
