Description of key information
Appearance / physical state / colour:
The appearance of 1,4-diamino-2,3-diphenoxyanthraquinone was observed to be violet colored odourless organic solid powder compound.
Melting point/ Freezing point:
Based on prediction done using MPBPVP v1.43, the melting point of chemical 1,4-diamino-2,3-diphenoxyanthraquinone was estimated to be 278.53 ˚C.
Boiling point:
The boiling point of 1,4-diamino-2,3-diphenoxyanthraquinone was determined to be 539.06 °C.
Density:
The density of 1,4-diamino-2,3-diphenoxyanthraquinone was determined to be 1.2876 g/cm3 at 25 °C.
Particle size distribution (Granulometry):
The particle size distribution of 1,4-diamino-2,3-diphenoxyanthraquinone was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 147 micron to 52 micron.
Vapour pressure:
The estimated vapour pressure of the test substance 1,4-diamino-2,3-diphenoxyanthraquinone at 25 deg C was 1.34E-011 Pa.
Partition coefficient:
The estimated logPOW of 1,4-diamino-2,3-diphenoxyanthraquinone was 5.59.
Water solubility:
The estimated water solubility of test substance 1,4-diamino-2,3-diphenoxyanthraquinone at 25 deg C was 0.00637 mg/l.
Surface tension:
Based on the prediction done by ACD labs, the surface tension for chemical 1,4-diamino-2,3-diphenoxyanthraquinone was predicted to be 68.0 ± 3.0 dyne/cm
Flash point:
The flash point of 1,4-diamino-2,3-diphenoxyanthraquinone was estimated to be 239.6 ± 27.8 °C.
Autoflammability:
1,4-diamino-2,3-diphenoxyanthraquinone did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 1,4-diamino-2,3-diphenoxyanthraquinone is not auto-flammable.
Flammability:
1,4-diamino-2,3-diphenoxyanthraquinone 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 1,4-diamino-2,3-diphenoxyanthraquinone is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 1,4-diamino-2,3-diphenoxyanthraquinone was considered non-flammable for chemical safety assessment.
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 there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
Stability in organic solvents and identity of relevant degradation products :
The study does not need to be conducted because the stability of the substance is not considered to be critical.
pH:
The pH of 1,4-diamino-2,3-diphenoxyanthraquinone was determined to be 7.00 ± 1.00.
Dissociation constant:
The pKa (dissociation constant) of 1,4-diamino-2,3-diphenoxyanthraquinone is estimated to be 0.30 ± 0.20 at 25 °C.
Viscosity:
The study does not need to be conducted because the given substance 1,4-diamino-2,3-diphenoxyanthraquinone is solid in nature. Hence study of this end point is considered to be waiver.
