Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 109 (Density of Liquids and Solids)

Temp.:

20 °C

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 – WH₂ × V_pyc/WH₁)

Relative density (D²⁰₄) is calculated as: δ_subs/0.999973

Conclusions:

Relative density: 1.756 at 20°C.

Executive summary:

Method:

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

Result:

Relative density: 1.756 at 20°C.

Description of key information

Pycnometer method - OECD guideline 109 - Relative density: 1.756

Key value for chemical safety assessment

Relative density at 20C:: 1.756

Additional information

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
