Applicant's summary and conclusion

Conclusions:
The vapour pressure of’ UC—136 was determined to be 2.5 ± 0.3 Pa at 25°C,
using the static technique.
In case the last measurements were extrapolated to 25°C, an estimation for
the upper limit of the vapour pressure of the pure compound could be made.
The upper limit of the vapour pressure for the pure compound i.e.
UC—136 was estimated to be < 0.1 Pa at 25°C.
