- experimental study
- Adequacy of study:
- key study
- Study period:
- 2016-08-01 to 2016-12-02
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- May 2008
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- 169.3 °C
- Atm. press.:
- 101.325 kPa
- Remarks on result:
- other: Mean of 3 replicate measurements, corrected for atmospheric pressure
- Conclusions:
- The test item has a boiling temperature of 169.3°C at atmospheric pressure (101.325 kPa)
- Executive summary:
The boiling point of the test item was assessed according to OECD 103, using the capillary method of Siwoloboff. In a preliminary experiment a boiling point of 171°C was determined (heating rate 10°C/min). In the main test, 3 replicate measurements were performed and the test material was heated at a lower heating rate of 0.5°C/min. The average boiling temperature at 99.48 kPa was found to be 168.7. The boiling point was corrected for atmospheric pressure (101.325 kPa): 169.3°C.
Reference
Preliminary test:
At 171°C the number of air bubbles increased.
Main test:
3 replicate measurements were performed. A clear normal boiling point with a current stream of bubbles evolving from the capillary was observed at 169.3°C.
Replicate | Pressure (kPa) | Temperature (°C) | corrected temperature (°C) |
1 | 99.48 | 168.3 | 168.9 |
2 | 99.48 | 168.8 | 169.4 |
3 | 99.48 | 169.1 | 169.7 |
Mean | 168.7 | 169.3 |
The correction factor used was 0.34 K/kPa
Description of key information
For this endpoint, 3 study results are available. The key study for this endpoint was the experimental study (2016) in which the boiling point was determined according to OECD 103, capillary method of Siwoloboff. The boiling point (corrected for atmospheric pressure) was found to be 169.3°C. As supporting studies, the results from the Merck Index (2001) and CRC Handbook (1993) were used. The boiling point results reported in these references are 165°C and 166.6°C respectively.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 169.3 °C
Additional information
The experimentally determined boiling point (OECD 103) was found to be 169.3°C.
