Key value for chemical safety assessment

Additional information

- No boiling point was observed in the range of the Siwoloboff measuring method (room temperature to 250 °C). Only the beginning of a brown discoloration is observed in the temperature region of 140 to 170 °C.

- The DSC analysis reveals an exothermic decomposition in the liquid state at about 168 °C. This decomposition explains the brown discoloration observed by the Siwoloboff method. Therefore the boiling point cannot be measured.

Using the Siwoloboff method , no exact boiling temperature could be detected. Only the beginning of a brown discoloration is observed in the temperature region of 140 to 170 °C. The DSC analysis reveals an exothermic decomposition in the liquid state at about 168 °C
