- Key result
- Atm. press.:
- >= 100.9 - <= 101.8 kPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 258 °C
- Remarks on result:
- not determinable

- The test substance decomposed before boiling.
- Conclusions:
- The test substance decomposed on heating from approximately 258 °C (532 K), both in air and under a nitrogen atmosphere. Therefore, the boiling temperature cannot be determined.
- Executive summary:
The boiling point of the test substance was determined according to OECD TG 103 following GLP principles. The determinations were carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86. The thermal behaviour of the test substance was investigated, not only in air, but also under a nitrogen atmosphere using a heating rate of 20.0 °C / minute and starting from 20.0 °C.
Due to the initial low rate of enthalpy change during decomposition, the onset temperature could only be approximated. From the six determinations, a mean onset temperature of 273 °C (546 K) was obtained from the pre-exotherm baseline limits, with a relative standard deviation value of 4.7 %. The extrapolated onset temperature of the first exotherm was much more repeatable, with a mean extrapolated onset temperature of 305 °C (579 K) and a relative standard deviation value of 0.8 %. However, the overall conclusion has been taken as the lowest onset temperature at which decomposition was detected, in order to present a worst case scenario for thermal stability.
The similarity between thermograms obtained in air and nitrogen atmospheres supported that the observed decomposition was thermal and not oxidative.
The test c decomposed on heating from approximately 258 °C (532 K), both in air and under a nitrogen atmosphere. Therefore, the boiling temperature cannot be determined.
