Key result
Flash point:
154 °C
Atm. press.:
1 atm
Remarks on result:
other: arithmetic mean of sevenfold determination
Conclusions:
flashpoint (closed cup) = 154°C
Executive summary:

The flashpoint of the test substance Octadecane has been determined to be 154°C (arithmetic mean of sevenfold determination), using the closed cup non-equilibrium method ASTM method D93 (procedure B).

Description of key information

- 154°C (closed cup; Shell, 2014)

Supporting information:

- 165°C (only indicative value since method unknown; Lange's Handbook of Chemistry, 1999)

- >149°C (data from safety data sheet, method unknown)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
154 °C

Additional information

The flashpoint of the substance Octadecane has been determined to be 154°C (arithmetic mean of sevenfold determination), using the closed cup non-equilibrium method ASTM D93 (procedure B).

The result is on the one hand in line with literature data (165°C acc. to Lange`s Handbook of Chemistry) and on the other hand, with a value derived from a safety data sheet (>149°C). However, these two values should be considered only as indicative because the used methods were unknown.
