Description of key information
Appearance:
Test chemical was observed to be a white coloured organic amorphous solid and it is odourless substance.
Melting point / freezing point:
The melting point determination of Test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The Mean melting temperature range was determine to be 179.6-183.5 °C at 977.5 hPa..
Boiling point :
Based on the data available from handbook, the boiling point of test chemical was determined to be 366.65 degree C.
Density:
The density of test chemical was determined following OECD guideline 109 and according to the method adapted from ASTM D 854-02. The mean density of the test chemical was determine to be 0.7110 g/cm³ at 20°C and 977.5 hPa.
Particle size distribution:
The particle size distribution of test chemical was determined by Granulometric analysis with Rotap sieve shaker. The particle size distribution was found to be in the range of 150 micron to 25 micron
Vapour pressure:
Vapour pressure of the test chemical was estimated to be 0.000272 Pa at 25 degree C.
Partition coefficient
The partition Coefficient n-octanol/water of test chemical was determined by Shake Flask Method. The study was performed at a temperature of 25°C. The log Pow value was determined to be 1.65 at a temperature of 25°C. On the basis of this value, test chemical can be considered to be hydrophilic in nature.
Surface tension:
In accordance with column 2 of Annex VII, this end point was considered for waiver since surface activity is not a desired property of test chemical
Flash point :
The flash point determination of test substance was done by closed cup method using Pensky Martin’s Flash Point Apparatus. The flashpoint of the test substance was determined to be 252°C at 977.4 hPa. Thus,it can be concluded that test chemical is a non flammable solid.
Auto flammability :
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:
This end point was considered for data waiver since there are no chemical groups in test chemical that can be associated with explosive properties
Oxidising properties:
During redox titration of test chemical, no end point was obtained. This suggest that test chemical has no oxidising property
pH:
The pH determination of test chemical was done as per the test guideline OECD 122. The mean pH of the test dispersion was determined with the help of digital pH meter. The mean pH was determine to be 3.10 at 23 °C.
Dissociation constant:
Test chemical was observed to be a dissociating solid with the pKa value of 0.034 obtained at 35 degree C.
Additional information
Appearance:
Test chemical was observed to be a white coloured organic amorphous solid and it is odourless substance.
Also, from other reliable sources, physical appearence of the test chemical was observed to be a yellow coloured solid having characteristic odour.
Melting point / freezing point:
The melting point determination of Test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The Mean melting temperature range was determine to be 179.6-183.5 °C at 977.5 hPa..
From other reliable sourcesit has been observed that, the melting point of test chemical was determined to be in the range of 179 - 183 degree C which supports the key value.
Boiling point :
Based on the data available from handbook, the boiling point of test chemical was determined to be 366.65 degree C.
From other experimental study report the boiling point of test chemical was observed to be greater than 300 degree C.
Density:
The density of test chemical was determined following OECD guideline 109 and according to the method adapted from ASTM D 854-02. The mean density of the test chemical was determine to be 0.7110 g/cm³ at 20°C and 977.5 hPa.
From other experimental study report, density of test chemical was determined to be 0.90 g/cm3 at temperature of 25 Deg C which is close to the experimental key value.
Particle size distribution:
The particle size distribution of test chemical was determined by Granulometric analysis with Rotap sieve shaker. The particle size distribution was found to be in the range of 150 micron to 25 micron.
Vapour pressure:
Vapour pressure of the test chemical was estimated to be 0.000272 Pa at 25 degree C.
