Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009-09-29
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Remarks:
- Test procedure in accordance with national standard methods (ASTM) without GLP.
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM-D1120
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- ebulliometer
- Key result
- Boiling pt.:
- 335 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Conclusions:
- A boiling point value of 335°C at atmospheric pressure, no decomposition was determined for the substance using a relevant test method. The result is considered to be reliable.
- Executive summary:
Octadecan-1-ol was determined according ASTM D1120. The boiling point was determined to be 636 °F (335 °C) at atmospheric pressure.
- Endpoint:
- boiling point
- Type of information:
- other: Data obtained from a handbook
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Principles of method if other than guideline:
- No details are available on the guideline used to determine this result.
- GLP compliance:
- not specified
- Boiling pt.:
- 210 °C
- Atm. press.:
- 15 mm Hg
- Conclusions:
- A boiling point value of 210ºC at 15 mmHg was reported in a handbookof reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable, though since it relates to a significantly reduced pressure it is not useful for the REACH technical data set.

Observed Boiling Point: 632.0°F / 640.0°F
Barometric Pressure: 766 mm Hg / 766 mm Hg
Equilibrium Boiling Point (Corrected): 631.5°F / 639.5°F
Description of key information
The boiling point of octadecan-1-ol is 335°C at 1013 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 335 °C
Additional information
A boiling point value of 335°C at 1013 hPa was determined for the substance in accordance with ASTM-D1120. The result is considered to be reliable and is selected as key study.
It is supported by a value of 210.5°C at significantly reduced pressure (15 mmHg), taken from 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.
