Applicant's summary and conclusion
- Conclusions:
- Vapour pressure measurements dropped during the successive runs (10) used in this study. The drop in readings appears to be due to the presence of an impurity in the test substance (most likely phenol). The reading for the final run was 0.069 Pa at 25 degrees C. The vapour pressure TPP was concluded to be at or below this final reading. Modeled data suggest that the vapour pressure of TPP may be even lower.
- Executive summary:
The vapour pressure for TPP was concluded to be at or below 0.069 Pa at 25 degrees C.
