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 21/01/2013 to 04/02/2013
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions

- 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)

- Type of method:
- method according to Siwoloboff
- Boiling pt.:
- 233 °C
- Atm. press.:
- 97 kPa
- Decomposition:
- no
- Remarks on result:
- other: =506 K; measured; accuracy +/-2K
- Key result
- Boiling pt.:
- 235 °C
- Atm. press.:
- 101.325 kPa
- Remarks on result:
- other: corrected to normal atmP
- 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 Patm.
Measured boiling point = 233°C under 97.0 kPa; Corrected boiling point = 235°C to normal Patm
Reference
| STAGE OF TEST | TEMPERATURE (K) | ||
| PRELIMINARY TEST | DETERMINATION 1 | DETERMINATION 2 | |
| Beginning of measurement | 311 | 475 | 487 |
| Bubbles were emerged from the capillary | 514 | 505 | 507 |
| Atmospheric pressure (kPa) | 97.0 | 97.0 | 97.0 |
Description of key information
Measured boiling point = 233°C under 97.0 kPa; Corrected boiling point = 235°C to normal Patm
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 235 °C
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Despite minor restriction due to heating rate, it is considered as a key study. The result is retained as key data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
