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.

Conclusions:
At 293K the density of test item compressed liquid is between 1425 and 1452 kg/m3
Executive summary:

The determination of the test item compressed liquid density have been determined according to a method which meet generally accepted scientific principles.

After calibration, the test item compressed liquid density was measured using a stainless steel vibrating U-tube.

At 293K (approx 19.85 °C) the density of test item compressed liquid is between 1425 and 1452 kg/m3

In 2 data coming from Knovel database, the density of the test item is indicated to be 1.553 g/cm3
Executive summary:

The density of the test item is indicated to be 1.553 g/cm3 at -20°C in 2 references coming from Knovel database.

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
