Neither the normal boiling temperature nor a boiling temperature at a reduced pressure value could be determined.

At approximately 70 °C the test item showed an increasing pressure value at a constant temperature. Additionally, the TGA

measurement shows a significant mass decrease at temperatures above 100 °C. Both behaviors can be justified by a decomposition

of the test item. Therefore, no boiling temperature at a meaningful pressure could be determined.

Since the static method is a measurement in a closed system, even small amounts of low boiling substances lead to higher pressure

values compared to open measurement methods, such as the gas saturation method.
