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:
- From 03/07/2012 to 24/07/2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised with its purity. Validation applies, with minor restrictions due to heating rate.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- yes
- Remarks:
- heating rate slightly exceed maximum of 1K/min as recommended
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- yes
- Remarks:
- heating rate slightly exceed maximum of 1K/min as recommended
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 15th and 16th November 2011 / Signed on 1st May 2012
- Type of method:
- method according to Siwoloboff
- Boiling pt.:
- 589 K
- Atm. press.:
- 97.4 kPa
- Decomposition:
- no
- Remarks on result:
- other: =316°C; measured; accuracy +/-2K
- Key result
- Boiling pt.:
- 591 K
- Atm. press.:
- 101.325 kPa
- Remarks on result:
- other: =318°C; corrected to normal atmospheric pressure
- Executive summary:
The boiling point of the test substance was determined under GLP according to OECD 103/EU A2 guideline, Siwoloboff (capillary) method. Two main runs were performed, and the mean value was corrected to normal atmP.
Measured boiling point = 316°C under 97.4 kPa; Corrected boiling point = 318°C (591K) to normal atmP

Description of key information
Boiling starts between 318 and 329°C (under normal atmP), depending on purity.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 318 °C
Additional information
Two reliable experimental studies, conducted according to a recognized OECD/EC method, are available. Despite minor restriction due to heating rate, both are considered as key studies, as relating to two different purities. The result for the highest purity is retained as key data for purpose of CSA.
