Reference
Thermal stability:
Up to the final temperature of the measurement of approximately 500 °C, no exothermal effect was observed. At a temperature of 440 °C, the course of the base line indicates a pressure increase. No endothermic effect was detected during the measurements.
Boiling point:
The measured boiling temperatures were corrected to normal pressure 101.325 kPa by the following number-value equation by Sidney Young. This method can be used due to the fact that the pressure during the test differs only slightly from normal pressure 101.325 kPa (max. deviation ± 5 kPa).
Tn: T + (fT×Δp) with Δp = (101.325−p)
p - pressure measurement in kPa
fT - temperature-correction factors for the rate of change of boiling temperature with pressure in K/kPa according to EC 440/2008
T - measured boiling temperature in K
Tn - boiling temperature corrected to normal pressure in K
