- Executive summary:
A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1 and EPA OPPTS test guideline 830.7200 to determine the melting point of the test item using differential scanning calorimetry. The test item was weighed out into a glass crucible under an inert atmosphere (nitrogen). Three tests with 9 – 25 mg of the test item were performed. As reference crucible, an empty glass crucible was used. The substance is a solid at ambient conditions. The crucibles were heated up to 500 °C (last test up to maximum 350°C) at a constant heating rate of 10 K/min. In the temperature range of 200 °C – 325 °C, an endothermal effect was observed in the three tests. Mass loss in the range of 18 - 30% was observed in all tests. After the measurements with a final test temperature of 500 °C the test item was still a solid. In consideration of the mass loss detected after the third measurement it can be assumed that the first endothermal effect is decomposition under release of water. Therefore the test item has no melting point up to 500°C. No observations were made which cause doubt of the validity of the outcome of the study.
Reference
Two DSC measurements with a heating rate of 10 K/min showed an endothermal effect in the temperature range of 200 - 325 °C and a second endothermal effect in the temperature range 370 - 440 °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. A third DSC measurement (final test temperature: 350 °C) showed an endothermal effect in the temperature range of 220 - 310°C.
After the measurements with a final test temperature of 500 °C the test item was still solid. In consideration of the mass loss detected after the third measurement it can be assumed that the first endothermal effect is decomposition under release of water.
