Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
