Results
Thermal stability
In the temperature range of 180 – 260 °C an exothermic effect was observed, with decomposition energy equal to -200 J/g. At 300 °C the test was terminated.

Table 1 – DSC measurement results

Sample weight [mg]	Start [°C]	Energy [J/g]
10.12	180 (exothermic)	-200

 

Effusion method – Knudsen Cell
Vapour pressure was measured in the temperature range of 30 to 110 °C. Measurements up to 55 °C are not shown because no evaluable vapour pressure could be detected up to that temperature.

Table 2 – Effusion method data

No.	Temperature [°C]	Vapour pressure [Pa]
1	86	4.65 x10^-3
2	91	4.51 x10^-3
3	94	7.83 x10^-3
4	96	3.85 x10^-3
5	99	5.37 x10^-3
6	101	5.01 x10^-3

 

Vapour pressures for 20, 25 and 50 °C are below the detection limit of < 10^-3 Pa. Vapour pressure as a function of the inverse temperature did not show the expected relationship and could not be used to derive values for the vapour pressure at lower temperatures.

Final vapour pressures are shown below, they were determined to be below the detection limits of the apparatus.

Table 3 – Final results

Temperature [°C]	Vapour pressure [Pa]
20	< 10^-3
25	< 10^-3
50	< 10^-3
