The following Antoine Equation was fit to the measurement data:
ln(P)= A + B/(C+T)
P is in mm Hg
T is in °C
A = 16.38429
B = -3820.722
C = 200.411
The boiling point of test substance, 760 mm Hg = 191.4 °C, was calculated from the Antoine equation shown above.
Description of key information
The boiling point of the test substance is 191.4 °C at 1013 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 191.4 °C
Additional information
The boiling point of the test substance was determined similar to OECD TG 104 by the dynamic method together with the vapour pressure determination. The boiling point of the test substance is 191.4 °C at 1013 hPa.
A supporting study from another laboratory reports a boiling point of 191.67 °C at 1019.9 hPa measured also by the dynamic method.
