Results and discussion

Boiling point
Boiling pt.:
>= -10 - <= 115 °C
Atm. press.:
ca. 101 325 Pa

Any other information on results incl. tables

Three endotherms were recorded: a first wide and flat signal between ca -10 and +35°C, a second small peak between ca 35 and 60°C, and a major peak between ca 60 and 110°C, with a maximum around 73°C.

For each boiling point assay, the crucible is weighted before and after filling and after measurement: the weights are identical, this validates that the test item is totally evaporated during the measurement.

Applicant's summary and conclusion

Executive summary:

The boiling point of the test substance was measured according to OECD103/EU A2 guideline, with the DSC method, under inert atmosphere.

Two DSC runs were performed, showing three successive endothermal signals, between ca -10 to +115°C, with a maximum peak at ca 73°C.

Considering the multi-constituent nature of the test item, the retained final result is the boiling range of -10 to 115°C.
