Results
Thermal Stability
An endothermic effect was seen in the temperature range of 30 to 50 °C.
An exothermic effect was seen in the temperature range of 180 to 260 °C,
with a decomposition energy of -120 J/g.

Effusion method – Knudsen cell
In the first measurement the vapour pressure was measured in the
temperature range of 10 to 25 °C, results are shown in table 2.

As the test item has a high molecular weight of ca. 850 g/mol and it is nearly solid at room temperature, a second measurement was done at higher temperatures. With this, it could be estimated if the vapour pressure values measured in the first series were caused by any low molecular substances, whose evaporation was detected. In the second measurement, the vapour pressure was measured in the temperature range of 81 to 101 °C, see Table 3.

Discussion
The second measurement showed that the vapour pressure from the first
measurement was due to the evaporation of low molecular components or
impurities. Therefore, the results from the second measurement series
were used for the final evaluation.
Although only three segments could be interpreted, the data point
of the second measurement can be assigned to the vapour pressure of the
test item. From the three measured data points of the second vapour
pressure curve, the constants A and B of the Antoine equation (Equation
2) can be derived by regression to:
A = 5.6569
B = -3150.27
C = 273.15
Conclusion
The vapour pressure of the test item calculated by extrapolation of the
measured vapour pressure curve for the temperatures 20, 25, and 50 °C is
shown in Table 4.
