- Executive summary:
A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1 and EPA OCSPP test guideline 830.7200 to determine the melting point of the test item using differential scanning calorimetry. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with about 12 – 19 mg of the test item were performed. As reference crucible, an empty aluminium crucible was used. In the thermograms of the DSC runs in the temperature ranges of 30 - 90 °C, 110 - 180 °C and 190 - 250 °C, three small endothermic effects were observed. Between 300 and 500 °C two exothermic effects could be detected. During the heating phase three small endothermic effects were observed, which can’t be clearly assigned to a melting of the test item. Thus, the capillary method was performed for a verification of the DSC-Measurements. At a temperature of 47.3 °C the test item started to soften and to become clear. At 149.7 °C the test item was partly molten and at 186.5 °C completely molten. Combining the results of the measurements, the first endothermic in the DSC can be assigned to a softening or a phase transformation of the test item. The second endothermic signal in the temperature range of 110 to 180 °C can be assigned to the melting of the test item. As the onset temperatures in both tests deviate by more than 0.5 K from their mean value of 126.02 °C, the test item has a melting range of 124 to 128 °C.
