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:
- Experimental phase: November 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study

- differential scanning calorimetry
- Key result
- Boiling pt.:
- 244.2 °C
- Atm. press.:
- >= 98.8 - <= 98.9 kPa
- Executive summary:
The boiling point of the test substance was determined according to OECD103/EU A.2 guideline, using Differential Scanning Calorimetry method.
Two main runs were performed, under nitrogen flow; the mean of peak temperature was retained.
The boiling temperature of the test substance has been determined to be 244.2 °C.
Reference
Assay 1: 244.7°C at 98.9 kPa
Assay 2: 243.6°C at 98.8 kPa
Assay 3: 242.8°C at 90.2 kPa
Mean (+/- Standard deviation) of assays 1 and 2*: 244.2 +/- 0.7 °C
The peak profiles are a little spread, this is probably due to the size of the hole in the commercial crucible top which generates a little evaporation before the boiling point. This early evaporation does not impact the accuracy of the boiling point since it is determined at the peak maximum.
For each boiling point assay, the crucible is weighted before and after filling and after measurement to validate that all the sample is vaporized. The weights of the three crucibles are the same before filling and after measurement, the test item is totally evaporated during the measurement.
Description of key information
Experimental boiling point under N2 = 244.2 °C under 98.9 kPa (not corrected to normal atmP).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 244.2 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method, is available. Therefore it is considered as a key study, and the result is retained as key data.
