Approximate accuracy of the instrument:
± 0.5 K (up to 600 K)
± 2.0 K (up to 1273 K)
At small deviations from the normal pressure (max. ± 5 kPa) the boiling temperatures are normalised to Tn by means of the following number-value equation by Sidney Young:
Tn = T + (fT x ∆p )
∆p = (101.325 – p)
where:
p = pressure measurement in kPa
fT = rate of change of boiling temperature with pressure in K / kPa (correction factor) = 0.44
T = measured boiling temperature in K
Tn = boiling temperature corrected to normal pressure in K
Description of key information

Additional information
A measured boiling point of 259.6°C (532.8 K) at 1013 hPa was determined for the substance using Differential Scanning Calorimetry (DSC) in accordance with OECD Test Guideline 103 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study. A predicted boiling point value of 280°C at 1013 hPa was also obtained for the substance using a validated QSAR estimation method.
In available secondary sources to which reliability could not be assigned, boiling point values of 98°C at 2 mmHg, 250°C at 1013 hPa, 257°C at 1013 hPa and 265°C at 1013 hPa were reported for the substance.
