Reference
The DSC curves showed a small exothermic effect (onset at 148 - 150 °C) probably caused by a reaction or decomposition; the substance changed from clear colourless to light yellow.
Under further heating a sharp endothermic peak (onset at 260 - 270 °C) was observed, probably caused by evaporation of the substance. The extrapolated onset temperature (280 - 282 °C) could be concluded to be the boiling temperature; however as discoloration of the substance had already occurred at a lower temperature, this should be regarded as the boiling temperature of the reacted and/or decomposed substance.
A further significant exothermic reaction occurred immediately after the endothermic reaction indicating further reaction and / or decomposition which is confirmed by a loss of sample weight (85 - 98%) and a further coloration (to brown).
Description of key information
In a GLP study according to test methods EC A.2 and OECD 103 (differential scanning calorimetry), the substance was determined to decompose at and above 148°C (Van der Baan-Treur, 2003).
Key value for chemical safety assessment
Additional information
The substance was concluded to decompose before its boiling temperature.
