Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test substance was 21.9 Pa at 25ºC.
- Executive summary:
The vapour pressure of substance was determined on the 17th February 1992 using the vapor pressure isotenuscope fitted with a vacuum arm manometer. The sample was initially held at around 201ºC and 318.5ºC mmHg pressure for about 15 minutes. Boiling took place and the sample showed no signs of decomposition. Around 1% of the sample was trapped in the distillation sidearm. Run 1 then followed and results obtained between 199 and 103ºC yielded a calculated vapur pressure value at 25ºC of :
Vp (25ºC)= 23.3 +/- 1.0 Pascuals.
The samples was then back flushed with nitrogen and held at around 200ºC and 279.5 mmHg pressure for 60 minutes. The sample boiled and again distillation into the sidearm was observed. Run 2 then followed and results obtained between 193 and 102ºC yielded a calculated vapour pressure value at 25ºC of Vp (25ºC)= 20.4 +/- 0.7 Pascals.
Runs 1 and 2 give results in reasonable agreement and the mean value i.e. Vp(25ºC)= 21.9 +/- 0.8 Pascals is considered to be an adequate estimate for regulatory purposes.
