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