Description of key information

The relative density of 1H-imidazolium, 1-ethyl-3-methyl-, acetate is 1.1011 at 20°C.

Key value for chemical safety assessment

Relative density at 20C:
1.101

Additional information

Two GLP studies were conducted in accordance with the OECD Guideline for the Testing of Chemicals 109: "Density of Iiquids and solids". The denslty was measured by an oscillating densitometer. BASF study no. 10L00259 determined the relative density of to be 1.1011 at 20 °C and BASF study no. 09L00094 determined the relative density to be 1.1017 at 20 °C.

Additionally the density was measured with the pycnometer method. The obtained density is 1.1085 at 20°C.

All values are in the same range and regarded to be reliable for 1H-imidazolium, 1-ethyl-3-methyl-, acetate.

The value of the recent study (10L00259) was chosen as key value.
