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 january 26, 2010 to january 27, 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Meets the requirements of GLP. There are no deviations from the recommended guideline that could affect the outcome of the study. One minor deviation is stated.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- yes
- Remarks:
- (The difference between the determinations is higher than 0.5 K. This is dueto the fact that the resolution of the thermometer is 1 K at temperatures above 200 ºC)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- yes
- Remarks:
- (The difference between the determinations is higher than 0.5 K. This is dueto the fact that the resolution of the thermometer is 1 K at temperatures above 200 ºC)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- 257.6 °C
- Atm. press.:
- 101.325 kPa
- Decomposition:
- yes
- Remarks on result:
- other: The result is the mean boiling point value corrected following the Sidney Young equation.
- Conclusions:
- The boiling point was determined as 257.6 °C (530.7 K) under decomposition.
- Executive summary:
The boiling point of the test substance was determined as 257.6 °C (530.7 K) under decomposition.
Reference
Experimental ValuesCorrected following the Sidney-Young equation:
Performance |
Boiling point |
Corrected Boiling Point |
First determination |
257.0 °C (1013.65 hPa) |
257.1 °C (530.2 K) |
Second determination |
261.0 °C (1012.97 hPa) |
261.1 °C (534.2 K) |
Third determination |
258.0 °C (1011.89 hPa) |
258.1 °C (531.3 K) |
The colour of the test item changed from clear, colourless to muddy yellow, this may be taken as sign of decomposition of the substance test.
The second determination showed a large variation to the other obtained values. Because the values of the first and third determination are quite close to each other it is believed that in the second determination, an error in the performance had occurred.
Therefore only the latter two experiments were considered to calculate the mean boiling point.
