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:
- 2013-03-04 to 2013-03-13
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Version / remarks:
- adopted 27 July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- dated 31 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Version / remarks:
- dated Aug 1996
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- 199 °C
- Atm. press.:
- 985.68 hPa
- Decomposition:
- yes
- Decomp. temp.:
- > 200 °C
- Conclusions:
- The boiling point was determined to be 199.0 °C at 985.7 hPa under decomposition.
- Executive summary:
A study was conducted according to OECD TG 103, Regulation (EC) No 440/2008 method A.2 and OPPTS 830.7220 to determine the boiling point of the test substance. Using the method according to Siwoloboff the boiling point was determined to be 199.0 °C at 985.30 hPa under decomposition. The measurement was performed in duplicate. The test item had changed its colour to brown-orange during the test. As the test item decomposes, a correction following Sidney-Young was not applied. No observations were made which might cause doubts on the validity of the study out-come. Therefore, the result of the study is considered valid.

For the calculation of the mean value and the evaluation, the result of the first determination was discarded, because the test item was set into the apparatus at 200 °C and therefore too late for a valid determination.
