- Executive summary:
A study was conducted according to OECD TG 102, EU Method A.1 and OPPTS 830.7200 to determine the melting point of the test item. The melting point of the test item was determined using the differential scanning calorimetry and the capillary method. 2.1 mg of the test item was weighed into a crucible and it was closed. The prepared crucible was inserted in the DSC and heated from room temperature to 500 °C at a constant heating rate of 10 K/min. A melting point of 70 °C in the DSC method was determined. Additionally, the melting point was determined with capillary method to be 80.8 °C. In the self-ignition study (IUCLID 4.12), a preliminary test was performed to determine the melting point and it was determined to be 80.1 °C. It is considered that the test items melting point is 80.8 °C. Above 119 °C the test item started to decompose.
Reference
DSC test:
At the start of the experiment, the substance appeared as red-brown solid; at the end of the experiment the substance appeared as dark red-brown solid. Initial weight of the test item was 2.1 mg and after analysis residue was found to be 0.8 and 0.9 mg.
During the DSC heating up phase, an endothermic reaction was recorded between 34 to 96 °C, which can be reasonably attributed to the melting point. Around the temperature of 119 °C the substance undergoes decomposition, through a series of successive endo-exo-endo-thermic reactions.
Capillary test:
The test item melted at 80.8 °C and no visual change was observed.
In the self-heating temperature study (IUCLID 4.12), a preliminary test to determine the melting point of the test item was performed. The melting point was determined to be 80.1 °C. As the test item is a multi-constituent substance, the DSC method is not an accurate method to determine the melting point of the test item. A more reliable result was acquired using the capillary method. Therefore, the melting point is considered to be 80.8 °C and above 119 °C the test item starts to decompose.
Description of key information
The melting point of the test item was determined to be 80.8 °C. Above 119 °C the test item started to decompose.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 80.8 °C
