- Executive summary:
A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1. The melting range was determined by differential scanning calorimetry. The test item and the reference are heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded. A measurement with the capillary method was performed to clarify the results of the DSC measurements.
The test item showed three endothermal effects. The first was observed with an onset temperature of 102 - 105 °C in the DSC-measurement (optical observation: no effect was observed). The second endothermal effect consisted of two phases. During the first phase (starting at approximately 130 °C) the test item started to melt. During the second phase (starting at approximately 140 °C) the test item melted completely to a clear liquid.
Reference
Melting point / melting range: DSC measurement
Two DSC measurements with a heating rate of 10 K/min showed an endothermal effect (melting) in the temperature range of 100 - 120 °C. Another two-phase endothermal effect was observed in the temperature range of 130 - 150 °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. The first measurement showed an exothermal effect starting 175 °C (this effect could have been caused by a reaction with the material of the crucible.
The results of the DSC measurements are summarized in Table 1.
Table 1: Melting point (DSC measurements)
Ident No. | Test item/ mg | Starting temperature / °C | Final test temperature / °C | Temperature range (melting) / °C | Onset / °C | Crucible | Observations after the measurement |
36358 | 14.34 | 25 | 500 | 100 - 120 130 - 150 | 104.05 multistage | Aluminium with a hole | Mass loss: 37 % |
36361 | 11.17 | 25 | 170 | 100 - 115 130 - 150 | 102.62 multistage | Aluminium with a hole | Test item was an orange melt No mass loss |
An additional measurement with the capillary method was performed in order to clarify the melting range.
Melting point / melting range: capillary tube in a metal block
A measurement with the capillary method was performed to clarify the results of the DSC measurements. Since this measurement was performed only as a verifying screening a high heating rate of 10 K/min was chosen and therefore the absolute temperature values derived with the capillary method are not as accurate as the DSC results. The filling height of the test item was approximately 5 mm.
The results are summarized in Table 2.
Table 2: Results of the capillary method
No. | Set point/°C | Heating rate/ K/min | Endpoint/ °C | Remarks |
1 | 80 | 10 | 160 | Approx. 135 °C: test item started to melt Approx. 142 °C: test item appeared melted and clear |
