During the heating phase an endothermic effect can be observed in the temperature range of 60 – 190 °C, which can be assigned to with the boiling of the test item.
For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 2 (e.g. Ketone). A correction value φ = 4.9 was used for the temperature range from 160 °C to 170 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 167.33 °C and the highest onset temperature to be 168.98 °C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 168.16 °C, the test item has a boiling range from 167 °C to 169 °C.
No further thermal effects were observed up to the test end temperature of 500 °C.
Final Results
The test item has a boiling range of 167 to 169 °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: 167 to 169 °C at 1013 hPa (EU Method A.2., differential scanning calorimetry)
Key value for chemical safety assessment
Additional information
A boiling range of 167 to 169 °C (at 1013 hPa) was determined for the test substance according to E.U. Method A.2.
