After heating to 400 °C, the test item had lost 49% and 48% of the original mass for Determinations 1 and 2 respectively.

Boiling point:             Decomposition from approximately 215ºC(488 K)

Applicant's summary and conclusion

Conclusions:
The test item was determined to decompose from approximately 215 °C (488 K) at 100.8 kPa. As the test item decomposed, no boiling point could be determined.
Executive summary:

The determination was carried out 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 and Method 830.7220 of the OCSPP Guidelines, August 1996.

Conclusion

The test item was determined to decompose from approximately 215 °C (488 K) at 100.8 kPa. As the test item decomposed, no boiling point could be determined.
