- Conclusions:
- In a GLP study conducted according to Directive 84/449/EEC of 24 April 1984, Method A.4 (vapour pressure balance), the vapour pressure was determined to be 2.0 E-5 hPa at 25 °C.
Reference
Above 70 °C melting of the test substance was observed due to the typical temperature course of the melting process. Vapour pressures between 70 and 88 °C are lower then the value measured at 68 °C and show a slight temperature dependence. For the extrapolation to the lower temperatures as shown in the table, the data measured above 70 °C were not considered. The measured vapour pressure data were evaluated in the temperature range between 52,9 and 68,2 °C.
