The regression of the results leads with a mean deviation of 0, 12 % to the following equation:
ln(p/hPa) = 19.2062-4196.33 / (241.33 + t/°C)
As a check, a low-temperatur reading was repeated. At 49.43°C a vapour pressure of 119.0 hPa was found.
The test item is liquid in the temperature range used for the vapour pressure measurements.
The Henry's law constant was not calculated because the water solubility is not within the range of applicability.
Applicant's summary and conclusion
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
