Results
Vapour pressure was examined at nine different temperatures. No temperatures could be evaluated, because they showed no reproducible weight loss.
Therefore a calculation on base of the measured weight losses was not possible the highest vapour pressure, derived from all measurements is stated as limit value.
The first measurement of experiment 1 (nominal temperature 30 °C) was not used for determination of the limit value as at the first measurement substances with a higher vapour pressure can evaporate.
Limit value
Vapour pressure at 105 °C: 3.01E-03 Pa
Discussion
The vapour pressure of the test item was determined at nine different temperatures (30, 45, 60, 75, 90, 105, 120, 135 and 150 °C) following EU A.4 using the effusion method (weight loss). All experiments showed no reproducible weight loss. Therefore only a limit value can be stated with 3.0110E-03Pa. The first measurement of experiment 1 (nominal temperature 30 °C) was not used for determination of the limit value as at the first measurement substances with a higher vapour pressure can evaporate.
No experiments could be evaluated as they showed no relevant and reproducible weight loss.
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.
