Results
In the thermograms of the two DSC runs (nos. PN7356 and PN7368) an endothermic (melting) effect was observed in the temperature range of -60 °C to - 45 °C. Between 100 to 265 °C a second endothermic effect (boiling) could be detected.

The test item showed a second distinct endothermic signal in the temperature range of 100 to 265 °C that can be associated 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 (eg. Hydrocarbons). According to appendix 7.2 a correction value φ = 5.1 was used for the temperature range from 240 °C to 250 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 246.59 °C and the highest onset temperature to be 246.75 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 246.67 °C, the test item has a boiling range from 246.7 °C.
No further thermal effects were observed up to the test temperature of 500 °C.
Final Results
The test item [trade name] has a boiling point of 246.7 °C at atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Directive EC440/2008 Method A.2., OECD Test Guideline 103 (1995), EPA OCSPP 830.7220 (1998).

The test item showed a second distinct endothermic signal in the temperature range of 100 to 260 °C that can be associated 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 (eg. Hydrocarbons). According to appendix 8.2 a correction value φ = 5.05 was used for the temperature range from 240 °C to 250 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 243.21 °C and the highest onset temperature to be 243.27 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 243.24 °C, the test item has a boiling point of 243.2 °C.
No further thermal effects were observed up to the test temperature of 500 °C.
Final Results
The test item [trade name] has a boiling point of 243.2 °C at atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Directive EC440/2008 Method A.2., OECD Test Guideline 103 (1995), EPA OCSPP 830.7220 (1998).
