Temperature program:

Pre-Study : Peaks assigned to the boiling of the substance were observed and measurement was stopped at 435°C

First determination with Atmospheric pressure 978.0 hPa :

The melting point was observed at -85.4°C (onset temperature of the first peak)

The initial boiling point was observed at 269.1 °C (onset temperature of the second peak) and a corresponding mass loss is observed on the TG curve, showing that all the substance was evaporated at the end of the study.

The crucible was visually checked after the determination: By opening the crucible, no test item left in the crucible and no sign of decomposition was observed.

Second Determination with Atmospheric pressure 977.0 hPa :

The melting point was observed at -85.0°C (onset temperature of the first peak)

 The initial boiling point was observed at 269.4 °C (onset temperature of the second peak) and a corresponding mass loss is observed on the TG curve, showing that all the substance was evaporated at the end of the study.

The crucible was visually checked after the determination: By opening the crucible, no test item left in the crucible and no sign of decomposition was observed.

The apparatus is checked with the reference substance Indium.

For temperature, the expected melting point: 156.6 +/- 0.5°C(reference value rounded up due to the temperature resolution of the apparatus used)

Obtained melting point: 156.6°C

The melting point of the Indium respects the defined tolerance of the expected melting point.

For sensitivity, the expected enthalpy: 28.6 +/- 2.9 J/g

Obtained enthalpy: 28.11 J/g

The enthalpy of the indium respects the defined tolerance of the expected enthalpy.

Conclusions:

The boiling point of test item was determined using a Differencial Scanning Calorimetry (DSC) and following the OECD Guideline 103, “Boiling Point” dated 27. July 1995 and the Regulation EC No. 440/2008 Method A.2.
After correction using the Sydney Young equation, the initial boiling point of the substance was determined as 270.9 °C at 101.3 kPa (mean of 270.7 °C for the first determination and 271.1 °C for the second determination).
