- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- 207.3 °C
- Atm. press.:
- 101.4 kPa
- Decomposition:
- no
- Remarks on result:
- other: ± 0.5 °C (480.5 ± 0.5 K)
- Conclusions:
- Under the conditions of this study, the boiling temperature of the test material has been determined to be 207.3 ± 0.5 °C (480.5 ± 0.5 K) at 101.4 kPa.
- Executive summary:
The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103 and EU Method A.2., under GLP conditions.
Aliquots of test material were placed in crucibles with pre-pierced lids. The samples were prepared and stored under nitrogen, each sample was then placed individually onto the DSC for immediate analysis. The samples were subjected to a thermal program from 20 to 400 °C at a rate of 20 °C/min. The appearance of the samples (residue) was recorded after the test.
The observed boiling temperatures were 207.36 °C (480.51 K) and 207.28 °C (480.43 K) for determinations 1 and 2, respectively. The small endotherm at approximately 100 - 120 °C was considered to be due to volatile impurities in the test material.
Under the conditions of this study, the boiling temperature of the test material has been determined to be 207.3 ± 0.5 °C (480.5 ± 0.5 K) at 101.4 kPa.
Reference
Determination 1:
Boiling temperature = 207.36 °C (480.51 K)
Determination 2:
Boiling temperature = 207.28 °C (480.43 K)
The small endotherm at approximately 100 - 120 °C was considered to be due to volatile impurities in the test material.

Additional information
The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103 and EU Method A.2., under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Aliquots of test material were placed in crucibles with pre-pierced lids. The samples were prepared and stored under nitrogen, each sample was then placed individually onto the DSC for immediate analysis. The samples were subjected to a thermal program from 20 to 400 °C at a rate of 20 °C/min. The appearance of the samples (residue) was recorded after the test.
The observed boiling temperatures were 207.36 °C (480.51 K) and 207.28 °C (480.43 K) for determinations 1 and 2, respectively. The small endotherm at approximately 100 - 120 °C was considered to be due to volatile impurities in the test material.
Under the conditions of this study, the boiling temperature of the test material has been determined to be 207.3 ± 0.5 °C (480.5 ± 0.5 K) at 101.4 kPa.
