Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of BICYCLO 2.2.1-HEPTA-2,5-DIENE - BCHD was measured using the static method as described in EU method A.4. Determination was performed with increasing and decreasing temperatures. Pairs of temperature/pressure obtained were used to define a regression equation, from which vapour pressure at 20°C and 25°C has been estimated.
Vapour pressures obtained for each temperature during the increasing and decreasing phases trials did not vary by more than 20% and the linear function obtained own a correlation coefficient R² over 0.95.
Moreover the calculated values showed good correspondence with the experimentally determined ones.
In conclusion, the vapour pressure of BICYCLO 2.2.1-HEPTA-2,5-DIENE - BCHD is 7259 Pa at 20°C and 9126 Pa at 25°C.
