Description of key information

232°C (decomposition)

Key value for chemical safety assessment

Additional information

The decomposition of the test substance HYEQS (LotDEG4052477) was determined by differential scanning calorimetry (DSC). The boiling point was calculated using Syracuse EPIWIN Software.

Result:

HYEQS decomposes at 232 °C (method: DSC, 3K/min).

The calculated boiling point is 509 °C.

For product safety purposes, the boiling point should be given as the decomposition temperature, 232 °C.
