Description of key information

Decomposes at >234°C before boiling.

Key value for chemical safety assessment

Additional information

1. Statement by determination using DSC method:.

The decomposition temperature beginns about 234°C corresponds to the temperature region where a brown discoloration of the substance is observed by the determination of the boiling point with the Siwoloboff method.

2. Statement by determination using Siwoloboff method (cited in Report on Vapour Pressure Curve and Boiling Point):

The boiling point of the substance could not be determinated by the Siwoloboff method, because the decomposition begins earlier than the boiling point. Therefore the boiling point of the substance was calculated from the thermogravimetric measurement ( Diffusion controlled evaporation).

The boiling point was measured to be 143°C at 11 Pa and extrapolated to be 367°C at 1013 hPa.
