The DSC-curve of the first run
(heating rate of 20 K/min from 25°C to 400°C) is shown in Figure 1
attached. An endothermic heat effect, boiling was observed between 256°C
and 345°C. After the experiment, the sample had lost about 95.7% of its
In order to determine the boiling
range more precisely, further DSC runs were recorded between about 200°C
and 400°C with a heating rate of 10 K/min. In the second run, the
boiling range was determined to be between 277.2°C and 346.7°C. During
this run, the sample lost 85.6% of its mass. After the measurement, the
sample was clear, colourless and liquid.
In the third run, the boiling
range was determined to be between 259.1°C and 334.9°C. During this run,
the sample lost 94.2% of its mass. The DSC curve of this measurement is
given in Figure 2 attached. The sample was unaltered in appearance.
As the temperature of the
endothermic effect was not very well reproducible, it can only be
calculated that the boiling point will be most probable in the range of
about 268°C to 342°C (541 K to 615 K).
The results are summarised in
Table 1 below.

Boiling range: 268°C to 342°C at
1013 hPa (OECD 103)
A boiling range of 268°C to 342°C
at 1013 hPa was determined for the substance using Differential Scanning
Calorimetry (DSC) in accordance with OECD Test Guideline 103 and in
compliance with GLP. The result is considered to be reliable.
