- Conclusions:
- The test item has a melting point of 210.8 °C at atmospheric pressure (1004.6 hPa) as determined by differential scanning calorimetry and capillary method according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).
Reference
The test item shows two endothermic effects in the temperature ranges of 200 °C - 230 °C and 300 °C - 380 °C.
The shape of the second endothermic effect suggests that the test item starts to decompose at approx. 290 °C; in view of the weight loss of the sample the decomposition is accompanied with gas formation and/or boiling of the decomposition products. In order to investigate if the first endothermic effect observed in the temperature range from 200 °C - 230 °C can be associated with a melting of the test item further measurements were carried with the capillary method.
Capillary Method
For verification of the results the test item was additionally tested three times according to the capillary method. In the three tests, the test item melted at a temperature of 221.6 °C, 221.6 °C and 221.7 °C, respectively (mean value: 221.6 °C). At a temperature of 260 °C, the test item started to climb in the capillary. At a temperature of 280 °C, the test item started to turn dark. At a temperature of 315 °C the test item was black. The measurements carried out with the capillary method showed that the first endothermic effect observed in the DSC measurements in the temperature range of 200 °C - 230 °C can be assigned to a melting of the test item. As the onset temperatures of the first endothermic effect observed in the DSC measurements do not deviate by more than 0.5 K from their mean value of 210.80 °C, the melting temperature is reported as 210.8 °C.
Description of key information
The test item has a melting point of 210.8 °C at atmospheric pressure (1004.6 hPa) as determined by differential scanning calorimetry and capillary method according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 210.8 °C
