Any other information on results incl. tables

As a result of the low rate of enthalpy change during decomposition, the onset temperature could only be approximated.

The onset of decomposition was taken at the point the downward drift of the baseline began to go exothermic. It was considered that the initial stages of the exothermic event could have been additional reaction of the components. Even so, the appearance of the residues demonstrated that ultimately the test item decomposed. The loss in mass of the residue was attributed to volatilization of the degradation products.

Applicant's summary and conclusion

Conclusions:
The test item has been determined to decompose from approximately 104 °C (377 K) at 100 to 101 kPa. As the test item decomposed, no value for boiling temperature could be determined.
Executive summary:

Boiling Point. Decomposition from approximately 104 °C (377 K) at 100 to 101 kPa, 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. As the test item decomposed, no value for boiling temperature could be determined.
