m₁= mass of empty pycnometer in g

m₂= mass of pycnometer with water in g
m₃= mass of pycnometer with replacement liquid in g

m₄= mass of pycnometer with solid test item in g

m₅= mass of pycnometer with replacement liquid and test item in g

 As water was used as replacement liquid the values of m₂and m₃are the same in both determinations.

Conclusions:

A density of 1.2822 ± 0.0003 g/cm3 at 20.0 ± 0.4 °C was measured with the test substance 4-Chlorobenzonitrile.

Executive summary:

Using the pycnometer method according to OECD 109 ("Density of Liquids and Solids") a density of 1.2822 ± 0.0003 g/cm³at 20.0 ± 0.4 ^°C was measured for 4-Chlorobenzonitrile. This value is the mean of two independent determinations with the maximum error of a single determination.

Description of key information

Using the pycnometer method according to OECD 109 ("Density of Liquids and Solids") a density of 1.2822 ± 0.0003 g/cm3at 20.0 ± 0.4 °C was measured for 4-Chlorobenzonitrile. The density of 4-Chlorobenzonitrile was also reported in two different data sources to be 1.11 g/cm³ and 1.17 g/cm³ at 16.8 °C and 22 °C which support the test result.
