1 013 hPa

Decomposition:

no

Remarks on result:

other: no endothermal effect observed after melting

Conclusions:

The test item had no boiling point at atmospheric pressure (1313.3 hPa).

Executive summary:

A study was conducted according to OECD TG 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. The test item was weighed into an aluminium crucible under an inert atmosphere (nitrogen). The crucibles were heated from room temperature up to 500 °C at a constant heating rate. A supplementary test using the capillary method was performed with the test item. In this method the test item was filled in a capillary which was then inserted in a metal block. Then the block was heated from 200 °C to the maximum temperature of the device (410 °C) with a heating rate of 10 K/min. The test item showed two endothermal effects. The first was observed with an onset temperature of 108 - 109 °C in the DSC-measurement (optical observation: no effect was observed). The second effect was observed with an onset temperature of 145 °C in the DSC-measurement (optical observation: start of melting at 141 °C, completely melted at 150 °C). The test item showed no endothermal effect after melting. Hence, the test item had no boiling point at atmospheric pressure (1313.3 hPa).
