Description of key information

Determined under composition.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
262 °C

Additional information

As the test material decomposed, no value for the boiling temperature could be determined experimentally. However, using an adaptation of the Stein and Brown method (Syracuse Research Corporation Inc. MPBP for Window version 1.40, William Meylan, 1994 -1999), the boiling temperature of the component with the lowest molecular weight was calculated to be > 400ºC).

The decomposition observed in the air atmosphere is partially oxidative and partially thermal as some decomposition was observed under nitrogen.
