- Atm. press.:
- 101.3 kPa
- Executive summary:
The boiling point of the test substance was determined under GLP according to OECD 103 / EU A2 guideline, using the DSC method.
Three main runs were performed, under inert atmosphere. Boiling occurs as a single peak.
After correction using the Sydney Young equation, the initial boiling point of the substance was determined as 221.6°C at 101.3 kPa.
Reference
First Determination
Mass taken: 14.15 mg
Initial boiling point was observed at 220.3°C (onset temperature of the peak) and a mass loss of 14.016 mg (99.1%) was observed between the beginning and the end of the boiling peak.
The crucible was visually checked after the determination: By opening the crucible, no test item left in the crucible and no sign of decomposition was observed.
Atmospheric pressure: 98.3 kPa..
Second Determination
Mass taken: 14.35 mg
Initial boiling point was observed at 219.9°C (onset temperature of the peak) and a mass loss of 14.343 mg (100.0%) was observed between the beginning and the end of the boiling peak.
The crucible was visually checked after the determination: By opening the crucible, no test item left in the crucible and no sign of decomposition was observed.
Atmospheric pressure: 97.3 kPa.
Third Determination
Mass taken: 13.54 mg
Initial boiling point was observed at 219.9°C (onset temperature of the peak) and a mass loss of 13.471 mg (99.5%) was observed between the beginning and the end of the boiling peak.
The crucible was visually checked after the determination: By opening the crucible, no test item left in the crucible and no sign of decomposition was observed.
Atmospheric pressure: 97.2 kPa.
Sydney-Young Correction
The corrected values at 101.3 kPa following Sidney-Young equation were determined to be 221.5°C for the first determination, 221.6°C for the second determination and 221.6°C for the third determination.
A third determination was performed because the final melting point values (measured during the same assay) of determinations 1 and 2 did not respect validity criteria (no more than 0.5°C of difference up to 326.85°C). According to the study plan, the two measurements with the closest results were taken into account. In our case, determinations 1 and 3 were retained and comply with the validity criteria. The same average was applied for the initial boiling point.
Description of key information
Experimental boiling point = 221.6°C (corrected to normal atmP, under inert atmosphere). (OECD 103, DSC; GLP)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 221.6 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as key study, and the result is retained as key data.
