Applicant's summary and conclusion

Conclusions:
The vapor pressure of AES was estimated to be 1.21 x E-12 Pa at 25 °C.
Executive summary:

The boiling point of AES was calculated to be approximately 515.16 °C using Meissner’s method.

The vapor pressure of AES was estimated to be 1.21 x E-12 Pa at 25 °C based on the boiling point calculated and using the Modified Watson Correlation. The vapor pressure was calculated for a molecule with covalent bands. Using the Meissner’s method for the calculation of the boiling point, it is not possible to take the ionic character into account. The calculation must be regarded as an estimation. The real vapor pressure of the AES is below 1.21 x E-12 Pa at 25 °C.
