During the heating phase a distinct endothermic effect was observed in the temperature range of 60 – 160 °C, which can be associated with the boiling point of the test item. The lowest measured onset temperature is corrected to standard pressure to be 99.17 °C and the highest to be 99.34 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 99.26 °C, the test item has a boiling point of 99.3 °C.
No further thermal effect were observed up to the maximum test temperature of 500°C.
Description of key information
Boiling point: 99.3°C at 1013 hPa
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 99.3 °C
Additional information
