The test item showed an endothermic signal in the temperature range from 230 - 380 °C that can be associated with the boiling of the test item.

For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 2 (e.g. Hydrocarbons). A correction value 5.125 was used for the temperature range from 283.95 to 285.85 °C.

The lowest measured onset temperature is corrected to the standard pressure to be 284.147 °C and the highest onset temperature to be 286.033 °C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 285.09 °C, the test item has a boiling range from 284 to 286 °C.

No further thermal effects were observed up to the test end temperature of 500 °C. After the DSC measurements a weight loss of about 97 % was detected in both tests.

Executive summary:

The boiling point of the test substance was determined under GLP according to EU Method A.2 and OECD 103, by differential scanning calorimetry (DSC). Two main runs were performed; as the difference between the individual results was greater than the estimated accuracy, the final result was expressed as a range.

The test substance has a boiling range from 284-286 °C corrected to normal atmospheric pressure (1013 hPa) under nitrogen.

Description of key information

Measured boiling range: 283.95-285.85°C. Corrected boiling range to normal atmospheric pressure (1013 hPa) under nitrogen : 284-286 °C

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study. The result being expressed as a range, it cannot be retained as (single) key data.
