Boiling Point / Boiling Range

The DSC-measurements in aluminium crucibles with a hole showed four endothermic effects in the temperature ranges 45 - 65 °C, 100 - 110°C, 150 - 185 °C and 280 - 290 °C and an exothermal decomposition beginning at a temperature of approximately 350 °C.

To verify the result of the DSC-measurement an additional measurement with the capillary method were performed:

No.	Set point	Heating rate	End point	Boiling point	Remarks
1	40 °C	20K/min	380 °C	-	105 °C: melting, turbid melt 178 °C: clear melt No change up to 380 °C
1	380 °C	5K/min	410 °C	-	No change of the clear melt, no boiling

 

The test item has no boiling point at atmospheric pressure. The test substance decomposes at approximately 350 °C before the boiling point is reached.

Conclusions:

The test item has no boiling point at atmospheric pressure. The test substance decomposes at approximately 350 °C before the boiling point is reached.

Executive summary:

A study was conducted according to OECD test guideline 103, Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item. First the differential scanning calorimetry was used. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Four endothermic effects in the temperature ranges 45 - 65 °C, 100 - 110 °C, 150 - 185 °C and 280 - 290 °C and an exothermal decomposition beginning at a temperature of approximately 350 °C were determined.

To verify the result of the DSC-measurement an additional measurement with the capillary method were performed.

The boiling/endothermic reactions started at 40°C and was not complete until decompositon at 350 °C. Thus, no boiling point could be established.
