Key result
Atm. press.:
ca. 1 atm
Decomposition:
yes
Decomp. temp.:
ca. 130 °C
Remarks on result:
other: No boiling point could be determined before the substance's decomposition at a temperature of approximately 130 °C.

Two DSC measurements with a heating rate of 10 K/min showed an endothermal effect in the temperature range of 40 – 75 °C.

The first DSC measurement additionally showed an exothermal effect starting at approx 130 °C indicating the decomposition of the test item. The decomposition of the substance was confirmed by the appearance of the sample after measurement (black residue) combined with a mass loss of 72 % of the initial weigh-in. No additional endothermal effects were observed after the first one between 55 °C - 80 °C and before the exothermal effect starting at approx. 130 °C. The observed exothermal effect indicated a decomposition of the test item and therefore no boiling point could be determined. Therefore, the test item has no boiling point under atmospheric conditions.

Conclusions:
The observed exothermal effect at a temperature of approx. 130 °C indicated the decompostion of the test item and therefore no boiling point could be observed under atmospheric conditions.
Executive summary:

The boiling point / boiling range of the test item was investigated by DSC measurement according to OECD 103. The study showed that the test item starts to decompose at a temperature of approx. 130 °C (indicated by an exothermal effect). No boiling point could be determined before the decomposition. Therefore, the test item has no boiling point under atmospheric conditions.
