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:
- 08 June 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- Commission Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), Method A.2, Official Journal of the European Union L 142 of 31 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- Organisation for Economic Co-operation and Development (OECD), Guidelines for Testing of Chemicals, Guideline No. 103, “Boiling Point”, adopted July 27, 1995
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Specific details on test material used for the study:
- No further details specified in the study report.
- Key result
- Atm. press.:
- 97 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 305 °C
- Remarks on result:
- not determinable
- Remarks:
- due to decomposition
- Conclusions:
- The observations demonstrate that the test item changes colour on heating, indicating decomposition occurs before boiling at normal atmospheric pressure. The definite Boiling Point for the Test Item is not definable at normal atmospheric pressure.
- Executive summary:
The boiling point of the test item was determined by the capillary method using a metal heating block. The test item is assessed visually for any possible changes in its appearance, consistency and colour.
The observations demonstrate that the test item changes colour on heating, indicating decomposition occurs before boiling at normal atmospheric pressure. The definite Boiling Point for the Test Item is not definable at normal atmospheric pressure.
Reference
The observations were as follows in each test:
At about 305 °C formation of bubbles began in the sample. At the same time the sample began to turn brown continuously, which disturbed the visual observations.
In parallel the rapid formation of small bubbles began, but it did not appear as a typical boiling normally appears.
The Main tests were carried out at 97.0 kPa atmospheric pressure.
The observations demonstrate that the test item changes colour on heating, indicating decomposition occurs before or in parallel with boiling at normal atmospheric pressure. The definite Boiling Point for the Test Item is ≥ 305 °C but due to decomposition the exact temperature is not definable at normal atmospheric pressure.

Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 305 °C
