guideline study
Qualifier:
according to
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)

no
GLP compliance:
no
Type of method:
pycnometer method
Type:
relative density
Density:

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 – WH 2 * V pyc / WH1 ) Relative density (D204) is calculated as: δ subs / 0.999973

Conclusions:
Relative density: 1.677 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: 1.677 at 20 °C.

Description of key information

Relative density: 1.677

Key value for chemical safety assessment

Relative density at 20C:
1.677
