Absolute density of a substance (δ) is calculated as:

δ subs = WS / V subs = WS / (V pyc – V hex ) = WS / (V pyc – WH2 / δ Hex ) = WS / (V pyc – WH 2 * V pyc / WH1 )

Relative density (D204) is calculated as: δ subs / 0.999973

Executive summary:

Method

Relative density was determined by means of pycnometer method as per recommendations of OECD 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.

Result

Relative density value found: 1.469 at 20 °C.

Description of key information

Relative density: 1.469

Key value for chemical safety assessment

Relative density at 20C:
1.469

Additional information

Relative density test was carried out according to the OECD Guideline 109. Relative density value found: 1.469 at 20 °C.
