Results and discussion
Vapour pressure
- Remarks on result:
- not determinable
Any other information on results incl. tables
The sample was degassed at 19 - 20 °C for approximately 18 hours overnight. During testing with the sample, the temperature was held at 50°C; however, the sample did not reach a stable equilibration over a 28 hour period. Over a 4.5 hour period the pressure was observed to increase from 0.2166 to 2.6 mbar. The sample was taking excessive time to reach an equilibrium pressure at a given temperature therefore it is suspected that the test material contains trapped solvents/ gasses or volatile impurities. Therefore, it is not expected that meaningful data can be obtained from this experiment.
Applicant's summary and conclusion
- Conclusions:
- The EC A.4 Static method proved to be not suitable for the determination of the vapour pressure of the substance as a pressure equilibrium at constant temperature could not be reached.
