Boiling pt.:

> 400 °C

Atm. press.:

>= 100.2 - <= 103.1 kPa

Decomposition:

Remarks:

minor possible decomposition

Any other information on results incl. tables

Atmospheric pressure:           100.2 to 103.1 kPa

Overall result:                        boiling point greater than 400°C (>673K)

Discussion

On analysis, no significant endotherms (beyond the melting of the test item at approximately 150 to 165 °C, as quantified inSection 4.1of this report) were observed when aliquots of test item were heated up to 400 °C. This, combined with a significant solid residue remaining on completion of each determination, indicated that the boiling point of the test item wasgreater than 400°C (>673K). The appearance of the remaining residues and a minor weigh loss of approximately 14 to 18% after cooling indicated minor possible decomposition during heating. However, the onset temperature for this process could not be identified or quantified from the thermal data generated.

Applicant's summary and conclusion

Conclusions:

The boiling point of the test item was determined to be greater than 400 °C (>673 K) at 100.2 to 103.1 kPa.

Executive summary:

BoilingPoint. Greater than 400 °C (>673 K) at 100.2 to 103.1 kPa, determined by differential scanning calorimetry, using a procedure designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
