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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
