Description of key information
Additional information
The physical and chemical properties are summarised in the following table:
Property | Value | Remarks |
Physical state at 20°C and 101.3 kPa | Solid | Form: Powder Colour: White-grey Odour: Odourless |
Melting/freezing point |
Decomposes in the range 400-500°C |
No melting point at atmospheric pressure. Test item decomposes before the melting point. |
Boiling point |
Not applicable |
A determination of boiling point is not applicable, as the substance is a solid which decomposes before boiling. |
Relative density |
2.844 |
Temp.: 20.0 °C. |
Vapour pressure |
< 1.0E-7 hPa |
|
Surface tension |
Not applicable |
Based on structure, surface activity is not expected or cannot be predicted. |
Water solubility |
Solubility at pH 7 (20°C): 2.03mg/L Solubility at pH 7 (30°C): 1.91mg/L Solubility at pH 4.1 (20°C): 23.9mg/L Solubility at pH 9 (20°C): 0.12mg/L |
The solubility of copper thiocyanate was tested at pH 7 in pure water saturated with atmospheric carbon dioxide. Solubility at pH 4.1 was determined in a solution of water and 0.2ml H2SO4 0.2M. Solubility at pH 9 was determined in borate buffer (50mmol/L). |
Partition coefficient n-octanol/water (log value) |
Not applicable |
A determination of partition coefficient is not applicable, as the substance does not dissolve in water or in octanol. |
Flash point |
Not applicable |
Flash point was not determined, as it is only relevant to liquids and low melting point solids. |
Flammability |
Not highly flammable |
|
Explosive properties |
Not applicable |
An assessment of explosive properties does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties. |
Self-ignition temperature |
364.13°C |
|
Oxidising properties |
Not applicable |
An assessment of oxidising properties does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties. |
Granulometry |
Volume-rated particle size distribution by laser diffraction: D(v,0.1) 2.38 µm; D(v,0.5) 8.65 µm; D(v,0.9) 16.43 µm Number-rated particle size distribution by laser diffraction: D(n,0.1) 0.453 µm; D(n,0.5) 0.668 µm; D(n,0.9) 1.300 µm |
Joint registrants that produce or import copper thiocyanate corresponding to this specification are able to refer to the Lead Registrants granulometry data for the purpose of REACH registration. The material does not fall under the category of nanomaterial (50% < 0.1 µm based on particle number). |
Stability in organic solvents and identity of relevant degradation products |
Solubility in 1,2-dichloroethane: < 10 g/L at 20°C Solubility in ethyl acetate: < 10 g/L at 20°C Solubility in n-heptane: < 10 g/L at 20°C Solubility in acetone: < 10 g/L at 20°C Solubility in methanol: < 10 g/L at 20°C Solubility in p-xylene: < 10 g/L at 20°C |
