Description of key information

Appearance

The test material was observed to be an extremely pale yellow liquid.

 

Melting/freezing point

The pour point of the test item was determined to be < -20 °C (253 K) (OECD 102 and EU Method A.1).

Boiling point

The test item was determined by differential calorimetry to decompose from approximately 198 °C (471 K) at 102 kPa (OECD 103 and EU Method A.2).

 

Relative density

The density of the test item was determined by the pycnometer method to be 940 kg/m3 at 20.0 ± 0.5 °C and the relative density was reported as 0.940 (OECD 109 and EU Method A.3).

Granulometry

The study does not need to be conducted because the substance is marketed or used in a non-solid or granular form.

 

Vapour pressure

The vapour pressure of the test item was determined by the balance method to be 5.39 x 10E-03 Pa at 25 °C (298 K), 4.28 x 10E-03 Pa at 40°C (313 K) and 3.23 x 10E-02 Pa at 100°C (373 K) (OECD 104 and EU Method A.4).

 

Partition coefficient

The partition coefficient of the test item was determined by the HPLC method to be greater than 1.0 x 10E10 with Log10 Pow >10.0 (OECD 117 and EU Method A.8).

Water solubility

The water solubility of the test item was determined by the flask method to be < 1.03 x 10E-04 g/L at 20.0 ± 0.5 °C (OECD 105 and EU Method A.6).

 

Surface tension

The study does not need to be conducted because water solubility is below 1mg/L at 20°C.

Flash point

The flash point of the test item was determined to be 232 ± 2 °C using the closed cup equilibrium method (EU Method A.9).

 

Auto–ignition temperature

The test item was determined to have an auto-ignition temperature of 410 ± 2 °C at 100.9 to 101.2 kPa (EU Method A.15).

Flammability

The test item is a liquid and, in line with ECHA Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7a: Endpoint specific guidance (Version 6.0; July 2017), relevant properties for classification of the substance as flammable are the determined flash point and boiling point. Further experimental investigation of flammability is therefore not required.

 

Explosive properties

The result for explosive properties was predicted negative based on the chemical structure of the test item (EU Method A.14).

 

Oxidising properties

The result for oxidising properties was predicted negative based on the chemical structure of the test item (EU Method A.21).
