Any other information on results incl. tables
THe behaviour of the test sample during measurement was as follows:
(1) At the pressure 101.325 kPa
The boiling point of the sample in the liquid phase was not constant. The sample began to boil at the temperature 331.5°C. During measurement the boiling temperature of tested sample in liquid phase fell gradually from 331.5 to 319.5°C. Simultaneously it was observed that gradual increase of intensity condensed vapour.
(2) At the pressure 6.7 kPa
The boiling point of the sample in the liquid phase was not constant. The sample began to boil at the temperature 293°C. During measurement the boiling temperature of tested sample in liquid phase fell gradually from 293 to 280°C
Simultaneously it was observed that gradual increase of intensity condensed vapour.
The decomposition temperature the tested sample begins approximately about 290°C.
Applicant's summary and conclusion
- Conclusions:
- From measurement boiling temperature follows:
- the boiling temperature was not constant
- the boiling temperature drop in liquid phase was 12°C at the pressure 101.325 kPa
- the boiling temperature drop in liquid phase was 13°C at the pressure 6.7 kPa
- gradual increase of intensity condensed vapour
The decompostion temperature the tested sample begins approximately about 290°C.
