- Boiling pt.:
- >= 245 - <= 248 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Conclusions:
- The test item has a boiling point in the range of 245-248 °C.
- Executive summary:
The test item has a boiling range of 245–248°C corrected to normal atmospheric pressure (1013hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
Reference
During the heating phase the test item showed an endothermic signal in the temperature range of approx. 70–270 °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 2 (e.g. Hydrocarbons or Methyl ethyl ketone). According to appendix 8.2 a correction value φ= 5.05 was used for the temperature of 240–250 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 245.40 °C and the highest onset temperature to be 247.50 °C. As the corrected onset temperatures in both tests deviate more than 0.5 K from their mean value of 246.43 °C, the test item has a boiling range of 245–248 °C.
Description of key information
The test item has a boiling point in the range of 245-248 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 245 °C
Additional information
One study is available for this end point. In this test, the boiling point was assessed by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
The test itemhas a boiling range of 245–248°C corrected to normal atmospheric pressure (1013hPa).
