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:
- 29 Jul - 24 Aug 2005
- 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:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 67/548
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Remarks:
- The crucible is heated at a constant heating rate (10 K/min). The measurement is carried out in a defined atmosphere (nitrogen). The amount of heat absorbed or released is measured and recorded. Aluminum crucibles with a small bore are used as containers.
- Key result
- Boiling pt.:
- 277 °C
- Atm. press.:
- 1 013.3 hPa
- Conclusions:
- The boiling point of the test item at atmospheric pressure is 277 °C.
- Executive summary:
The study was performed to assess the boiling point. The study was conducted in accordance with EEC Method for "determination of the boiling point", Directive 92/69/EEC, method A.2 which is in most parts equivalent to the OECD Guideline for Testing of Chemicals No. 103. The boiling point of the test substance is 277 °C (1013 hPa).
Reference
Validity criteria for the measurement of the boiling point:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| The heating rate should not exceed 10 K/min. | Heating rate was 5 K/min. | Yes |
| The mean of at least two measurements which are in the range of the estimated accuracy (accuracy for this method according to the guideline is +/- 0.5 K up to 600 K) is reported as the boiling temperature. |
Mean of two measurements were reported 277.21 °C and 277.12 °C at atmospheric pressure which are in the required accuracy range of ± 0.5 °C. | Yes |
| The measured boiling temperatures and their mean shall be stated and the pressure(s) at which the measurements were made shall be reported in kPa. The pressure should preferably be close to normal atmospheric pressure. | Single values 276.88 °C and 276.93 °C were reported at 1006/1009 hPa, respectively. Values were corrected to standard atomospheric pressure (1013.3 hPa) and also presented as mean value. | Yes |
