- 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.
Reference
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
