By differential scanning calorimetry 2 endothermic effects were determined:
1.) at 123 °C (endothermic range between 100 to 160 °C, determined in 3 independent measurements): with a weight loss of 13.6% (w/w) and no melting
2.) at 238 °C (endothermic range between 220 to 270 °C, determined in 3 independent measurements with 236.5 °C, 238.1 °C, 239.8 °C): complete or nearly complete weight loss.
These results were confirmed by a fourth test. By heating up to 160 °C the first endothermic effect was detected.
Then, after cooling down to 80 °C and heating up to 300°C, the 2nd endothermic effect was detected between 225 to 265 °C,
but there was no first endothermic effect.
In the capillary measurement test, following effects were detected: At 227 °C item starts to become discoloured, at 244 °C test
item turned to black, at 254 °C test item melted and boiled simultanously. At 260 °C substance became black.
Weight loss at 1st endothermic point corresponds to weight of water and can therefore be attributed to dehydration. 2nd endothermic point with complete or nearly complete weightloss is attributed to final decomposition.
Description of key information
At 123 °C, substance dehydration occurs and at 238 °C decomposition (OECD 102, DSC). Supporting data show decomposition >70 °C.
Key value for chemical safety assessment
