Executive summary:

According to the CRC Handbook of Chemistry and Physics (and Lange`s Handbook of Chemistry respectively), the boiling point of Octadecane is 316.3°C.

No further details are reported in the handbooks on the determination. Reported value is assumed to have been determined at STP (20°C, 101.3 kPa).

Description of key information

2) 316.3°C (CRC Handbook, 2005; Lange's Handbook of Chemistry, 1999)

3) 317°C (API, 1961)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
316 °C

Additional information

The two values obtained are from literature sources with no specific details of methodology.

The lower boiling temperature was chosen as the key value because it is also used in the ASTM standard test method for boiling range distribution of petroleum fractions by gas chromatography (ASTM D2887). The calibration mixture to be used for this ASTM standard procedure is a mixture of hydrocarbons (C5-C44) of known boiling point, whereby the boiling point of Octadecane is stated to be 316°C.

The available information is consistent and provides sufficient data to allow a reliable result to be determined.
