Additional information
Different studys werde coducted. BASF study 189.0611.1 reported the vapour presure of the pure substance to be 132.4 hPa at 20 °C; 170:2 hPa at 25 °C and 519 hPa at 50 °C.
A GLP study was conducted in accordance with "Methods for the Determination of Physico-Chemical Properties", Directive 84/449/EEC, Annex V Part A.4 using an isoteniscope. ICI GLP study RD 10635C determined the vapour pressure of the solution to be 87 hPa at 20 °C, 114 hPa at 25 °C ans 376 Pa at 50 °C. BASF study 2000.355 also used the solution for conduction. This study reports the vapour pressure of the solution to be 91.63 hPa at 20 °C, 119.71 hPa at 25 °C and 392.56 hPa at 50 °C.
The value from BASF study 189.0611.1 (pure substance) was chosen as key value for the vapour pressure.
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.
