Reference
The DSC-measurement in a closed glass crucible with the test item showed multiple endothermic effects in the temperature ranges of 55 °C – 100 °C, 100 °C – 140 °C, 165 °C – 210 °C and 215 °C – 280 °C.
Two DSC-measurements in aluminium crucibles with a hole showed multiple endothermic effects in the temperature range of 50 °C – 325 °C and 40 – 340 °C, respectively. The onset temperature is derived from the intersection of the tangent line with the highest slope of the endothermic peak with the baseline.

An optical inspection after the measurement showed that the test item was still solid. Due to this observation and the multiple endothermic effects it was assumed that the test item has neither melting point nor boiling point.
An additional measurement with the capillary method was performed in order to clarify the results of the DSC measurements.

The results from the capillary method confirmed that the test item has neither a melting point nor a boiling point. The test item starts both melting and boiling during the measurements, however both effects end before the test item is completely molten and completely vapourized, respectively. It can be assumed that the test item undergoes chemical changes during the measurements which prevent the complete melting and boiling, respectively, of the test item. Without further investigations the nature of these changes can not be determined.
The test item has no melting point and no boiling point. The test item showed several endothermic effects; however none of them can be assigned to a complete melting or boiling of the test item.
Test conducted under atmospheric pressure condition.
Description of key information
> 340 °C at ca. 1013 hPa (OECD 103, DSC)
Key value for chemical safety assessment
Additional information
The boiling point of the substance was determined by Differential Scanning Calorimetry according to OECD Guideline 102. The test item starts boiling during the measurements, however this effect ends before the test item is completely vapourized. It can be assumed that the test item undergoes chemical changes during the measurements which prevent the complete boiling of the test item.
The test item has no boiling point and showed several endothermic effects; however none of them can be assigned to a complete boiling of the test item; therefore the boiling point was derived to be >340 °C.
