Applicant's summary and conclusion
- Conclusions:
- A vapour pressure of 1E-11 Pa at 25 °C was estimated. Thus, the substance is to be considered non-volatile in aqueous solution.
- Executive summary:
The vapour pressure at 25 °C was estimated with a modified "Watson Correlation" (K.M. Watson; Ind. Eng. Chem.35, 398, 1943) which implies summations of structural and atomic increments for critical properties such as critical temperature, critical volume and critical pressure. The vapour pressure obtained by this method for the supercooled liquid was converted into the vapour pressure of the solid with a correction based on the melting temperature to give:
P = 10-11 Pa (25 °C)
