- Executive summary:
A study was conducted according to OECD TG 102 and Regulation (EC) No 440/2008 method A.1 to determine the melting point of the test item using differential scanning calorimetry. The test item was weighed into an aluminium crucible under an inert atmosphere (nitrogen). Open crucibles are used as containers for the test item and asThree DSC measurements with a heating rate of 10 K/min showed an endothermal effect (melting) in the temperature range of 75-110°C. Additionally the first measurement also showed an exothermal effect (175 – 225°C) and another endothermal effect (360 – 500°C). The endothermal effect consisted of two steps. However as the test item was already a melt after the first step only this was considered for the melting point. The test item had a melting point of 85.6 °C.
Reference
Three DSC measurements with a heating rate of 10 K/min showed an endothermal effect (melting) in the temperature range of 75-110°C. Additionally the first measurement also showed an exothermal effect (175 - 225 °C) and another endothermal effect (360 - 500 °C). The onset temperature (see Table 1) was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline.
