During the heating phase an endothermic effect was observed in the temperature range of approx. 180 - 240 °C that can be assigned to the boiling of the test item.
For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 8 (e.g. Alcohol). According to H.N. Hass and R.F. Newton table, a correction value φ = 6.4 was used for the temperature of 210 - 220 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 214.52 °C and the highest onset temperature to be 218.30 °C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 216.41 °C, the test item has a boiling range of 214 - 219 °C.
No further thermal effects were observed up to the maximum test temperature of 500 °C.
Final Results
The test item has a boiling range of 214 - 219 °C corrected to normal atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
Description of key information
Boiling range: 214 - 219 °C at 1013 hPa (EU Method A.2, differential scanning calorimetry)
Key value for chemical safety assessment
Additional information
The boiling point has been corrected to normal pressure (1013.25 hPa) using the H.N. Hass and R.F. Newton equation.
