Any other information on results incl. tables
Based on the simplified Clausius-Clapeyron equation a regression line was fitted on the measured data and the vapour pressure was extrapolated for 20 and 25 °C:
The results are as follows:
20 °C - 0.28 kPa
25 °C - 0.38 kPa
Applicant's summary and conclusion
- Conclusions:
- Based on the simplified Clausius-Clapeyron equation a regression line was fitted on the measured data and the vapour pressure was extrapolated for 20 and 25 °C, the results for this are shown below:
20 °C - 0.28 kPa
25 °C - 0.38 kPa - Executive summary:
Vapour pressure of Pellicer was determined using MINIVAP automatic vapour pressure tester according to ASTM D2879-86 (isoteniscope principle). Vapour pressure is a measure of the substance volatility, it indicates the probability of the phase transitions from liquid and solid to gas phase. It is a significant factor for predicting atmospheric concentrations.
The following result was obtained: Vapour pressure of Pellicer at 20 °C: 0.28 kPa Vapour pressure of Pellicer at 25 °C: 0.38 kPa
