Absolute density of a substance ( δ) is calculated as: δsubs = WS / Vsubs = WS / (Vpyc – Vhex) = WS / (Vpyc – WH2 / dHex) = WS / (Vpyc – WH2 * Vpyc / WH1) Relative density ( D²⁰₄) is calculated as: δsubs / 0.999973

Conclusions:

Relative density: 1.537 at 20 °C

Executive summary:

Method

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

Result

Relative density: 1.537 at 20 °C.

Description of key information

Relative density: 1.537 at 20 °C

Key value for chemical safety assessment

Relative density at 20C:

1.537
