- yes
- Decomp. temp.:
- 370 °C
- Remarks on result:
- other: Fog at 370 °C
- Conclusions:
- The boiling point of icosan-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 a decomposition at 370°C.
- Executive summary:
The boiling point of icosan-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 a decomposition at 370°C.

Description of key information
A commercial sample of icosan-1-ol was found to decompose without boiling at a temperature of 370°C and 999 mBar.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 370 °C
Additional information
The substance was found to undergoes thermal decomposition without boiling at a temperature of 370°C at 999 mBar in a reliable study according to ASTM-D1120.
Boiling at 309°C was reported in a reliable handbook. This result would reflect a pure sample.
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.
