A total of 80 compressed liquid density data points were measured at nine isotherms in the range between 263 K and 333K for at least eight pressures per isotherm ranging from a pressure slightly above saturation to 7000 kPa.
Value from generally accepted authoritative secondary source. No data available for pressure.
Description of key information
The determination of the test item compressed liquid density have been determined according to a method which meets generally accepted scientific principles.
After calibration, the test item compressed liquid density was measured using a stainless steel vibrating U-tube.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.44
Additional information
At 293K the density of test item compressed liquid is between 1425 and 1452 kg/m3. The key value chosen for chemical safety assessment was the mean value obtained at 293K: 1437 kg/m3 which corresponds to a relative density regarding water at 20°C of 1.44.
A supporting study based on data coming from an external database is also given. The density of the test item at -20°C is 1.533 g/cm3
