Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results of the measurement of the density of the test item

Test No.  Temperature [°C] Test item chamber size Reference vessel No. Weight in of test item [g] Density [g/cm³]* 
 1  20  Small (25.62 cm³) 21.35 cm³  20.7407  1.96786
 2  20  Small (25.62 cm³) 21.35 cm³  20.1257  1.96993

*The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) >0.02%.

The mean density of the test item at 20 °C is 1.968895 g/cm³ (SD= 0.0015, RSD = 0.08 %). The relative density D(4)20 is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).

The relative density is D(4)20 = 1.97

Conclusions:
According to OECD Test Guideline 109 (1995), the relative density D420 of the test item at 20°C ± 0.01°C (compared to water at 4°C) is D420 = 1.97.

Description of key information

The relative density D(4)20 of zirconium propionate is 1.97.

Key value for chemical safety assessment

Relative density at 20C:
1.97

Additional information

According to OECD Test Guideline 109 (1995), the relative density D(4)20 of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is D(4)20 = 1.97.
