Description of key information

Appearance / physical state / colour:

The physical appearance of test chemical was observed to be an organometallic solid in the form of red colored powder.

 

Melting point/ Freezing point:

Based on the prediction done using the EPI Suite MPVPBP V1.43, the melting point of test chemical was estimated. The melting point of chemical was estimated to be 318 ˚C.

 

Boiling point:

Based on the prediction done using the EPI Suite MPVPBP V1.43, the Boiling point of chemical was estimated. The boiling point of test chemical was estimated to be 725 ˚C.

Density:

Based on prediction done using ACD/I-Lab 2.0, the density of test chemical was estimated to be 1.83 ± 0.1 g/cm3.

 

Particle size distribution (Granulometry):

The particle size distribution of test chemical was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 150 micron to 53 micron.

 

Vapour pressure:

Modified Grain method (Mean of Antoine and Modified Grain methods) was used to estimate the vapour pressure of the test chemical using MPBPVP v1.43 of EPI SUITE. The vapour pressure of the test chemical at 25 °C was estimated to be 9.893E-17 Pa (7.42E-19 mm Hg).

 

Partition coefficient:

The partition Coefficient n-octanol/water of test chemical was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 117 for testing of Chemicals. The Log Pow value was determined to be 3.2 dimensionless at 25°C. This value indicates that the substance is hydrophilic in nature.

 

Water solubility:

The water solubility determination of test chemical was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determined to be 315 mg/L at 25°C.

 

Surface tension:

The study does not need to be conducted because surface activity is not a desired property of the material

 

Flash point:

The study does not need to be conducted because the flashpoint is the only relevant to liquids and low melting point solids

 

Autoflammability:

Test chemical did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that test chemical is not auto-flammable.

 

Flammability:

Test chemical does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that test chemical is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus test chemical was considered non-flammable.

 

Explosiveness:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.

 

Oxidising properties:

The study does not need to be conducted because substance is a solid
