- differential scanning calorimetry
- Key result
- Boiling pt.:
- 187 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Conclusions:
- A boiling point of 187°C at 1013 hPa was determined in accordance to an acceptable guideline method. This result is considered to be reliable.
Reference
The boiling temperature is determined from the extrapolated onset temperature of the endothermic peak. Since the ambient pressure deviates from the standard pressure, the measured boiling temperatures T were converted to normal boiling points Tn by means of the Sidney-Young equation.
Tn = T + (fT . Δp)
fT = 0.037 K/hPa
| extrapolated onset temperature [°C] | boiling temperature [°C] at 1013 hPa |
First run | 187.34 | 187.43 |
Second run | 187.08 | 187.17 |
Mean value | - | 187.30 |
Description of key information
Boiling point: 187°C at 1013 hPa (OECD 103)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 187 °C
Additional information
A boiling point of 187°C at 1013 hPa was determined for the submission substance in an experimental study using a differential scanning calorimetry method conducted according to OECD test guideline 103. This result is considered to be reliable and is selected as key.
The key result is supported by a predicted boiling point of 180°C at 1013 hPa, determined using a validated QSAR estimation method.
In available secondary sources to which reliability could not be assigned, boiling point values of 185°C at 1013 hPa and 73°C at 18 hPa were reported for the substance.
