Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- June 16, 2004
- Reliability:

- Deviations:
- yes
- Remarks:
- heating rate exceed maximum of 1 K/min as recommended
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:

- Remarks:
- Swiss GLP compliance programme (inspected on September 09 and 30, 2002/ signed on December 2002)
- Type of method:
- method according to Siwoloboff
- Specific details on test material used for the study:
- Storage condition of test material: Refrigerator (between 0 and 10 °C under nitrogen)
- Boiling pt.:
- 248 °C
- Atm. press.:
- 97.3 kPa
- Remarks on result:
- other: measured; accuracy ± 2 °C; 521 ± 2 K
- Key result
- Boiling pt.:
- 250 °C
- Atm. press.:
- 101.325 kPa
- Remarks on result:
- other: corrected to normal atmospheric pressure
- 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, the mean final temperature was retained and corrected to normal atmospheric pressure.
The normal boiling temperature of test substance has been determined to be 250°C.
Reference
Preliminary test: 520 K (247 °C) at 97.3 kPa
Determination 1: 521 K (248 °C) at 97.3 kPa
Determination 2: 521 K (248 °C) at 97.3 kPa
Description of key information
Measured boiling point = 248°C under 97.3 kPa; Corrected boiling point = 250°C to normal atmP.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 250 °C
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Despite minor restrictions due to technical inaccuracy, it is considered as a key study. The result is retained as key data for purpose of CSA.
