Applicant's summary and conclusion

Conclusions:
The three calculation models gave almost the same results so the values are judged to be accurate. The average value 0.21 Pa is reported.

Substances with this low vapour pressure are not very likely to vaporise and become airborne. The low predicted vapour pressure correlates with the experimentally derived boiling point of 260 °C.
Executive summary:
