Density:
Based on prediction done using ACD/I-Lab 2.0 and Scifinder, the density of chemical 1,4-diamino-2,3-dichloroanthraquinone was estimated to be 1.637 ± 0.06 g/cm3
Particle size distribution (Granulometry):
The particle size distribution of 1,4-diamino-2,3-dichloroanthraquinone was determined to be in the range of 150 micron to 53 micron.
Vapour pressure:
The estimated vapour pressure of substance 1,4-diamino-2,3-dichloroanthraquinone at 25 deg C was 0.00000000808 Pa.
Partition coefficient:
The Octanol water coefficient of test chemical 1,4-Diamino-2,3-dichloroanthraquinone was determined to be 4.56 by using slow stirring method at 25oC.
Water solubility:
The solubility of 1,4-diamino-2,3-dichloroanthraquinone in water was determined as, 0.08 mg/L as High aqueous solubility and 0.035 mg\L as Low aqueous solubility.
Surface tension:
Based on the prediction done by ACD labs, the surface tension for chemical 1,4-diamino-2,3-dichloroanthraquinone was predicted to be 82.4 ± 3.0 dyne/cm.
Flash point:
The flash point of chemical 1,4-diamino-2,3-dichloroanthraquinone was estimated to be 317.5 ± 31.5 °C
Autoflammability:
4,7-Dichloroquinoline did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 4,7-Dichloroquinoline is not auto-flammable.
Flammability:
4,7-Dichloroquinoline 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 4,7-Dichloroquinoline is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 4,7-Dichloroquinoline 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.
Additional information
Appearance / physical state / colour:
Based on available data from obtained reports, the appearance of 1,4-diamino-2,3-dichloroanthraquinone was observed as, purple-black colored solid crystal-powder organic compound.
Melting point/ Freezing point:
The melting point of 1,4-diamino-2,3-dichloroanthraquinone was determined using Linkam TMS91 melting point apparatus.
The melting point of 1,4-diamino-2,3-dichloroanthraquinone was determined as 294.85 °C (568 K)
Other supporting study from authoritative database Scifinder, exhibited the melting point of 1,4-diamino-2,3-dichloroanthraquinone as 295 °C, very much closer to the selected key value.
Boiling point:
Based on the prediction done using the EPI Suite MPVPBP V1.43, the Boiling point of chemical 1,4-diamino-2,3-dichloroanthraquinone was predicted.
The boiling point of chemical 1,4-diamino-2,3-dichloroanthraquinone was estimated to be 486.12 ˚C
