Results and discussion

Boiling point
Boiling pt.:
310 - 370 °C
Atm. press.:
95.8 - 98.2 kPa

Any other information on results incl. tables

A single accurate boiling point of the test material could not be determined. A continuous increase in the intensity of bubble formation was observed in 310 - 370 °C (583 – 643 K) temperature range.

Boiling of the test material was investigated at seven discrete temperature points. A continuous increase in the intensity of bubble formation was found in a wide temperature range. This is considered to be related to the multi-component mixture characteristics of the test item. At 370 °C very intense, continuous bubbling was observed in four experiments; bubbling frequency could not be measured in these cases.

Applicant's summary and conclusion

Conclusions:
A single accurate boiling point of the test material could not be determined. A continuous increase in the intensity of bubble formation was observed in 310 - 370 °C (583 – 643 K) temperature range.
Executive summary:

In a boiling point study (10/095-324AN), a single accurate boiling point of the test material could not be determined according to Method A2 of Commission Regulation (EC) No 440/2008. A continuous increase in the intensity of bubble formation was observed in 310 - 370 °C (583 – 643 K) temperature range.
