Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-02-04
- 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
- Atm. press.:
- 1 010.8 mBar
- Decomposition:
- yes
- Decomp. temp.:
- 392 °C
- Remarks on result:
- other: Fog at 392°C.
- Conclusions:
- The substance was observed to undrgoes thermal decomposition from 392°C using a relevant test method. The result is considered to be reliable.
- Executive summary:
The boiling point of docosan-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 an decomposition at 392°C.
Reference
Measurement:
barometric pressure:1010.8 mBar
Decomposition at:392°C
remarks of results:white fog at 392°C
Description of key information
A commercial sample of docosan-1-ol was found to decompose without boiling at a temperature of 392°C and 1013 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 392 °C
Additional information
The substance was observed to undergoes thermal decomposition at 392°C at 1013 hPa in accordance with ASTM D1120. The result is considered to be reliable.
This is supported by a boiling point of 180°C at 0.22 hPa which was reported for the substance in 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.
