103 kPa
Decomposition:
yes
Decomp. temp.:
151 °C
Remarks on result:
not determinable
Remarks:
The test item has been determined to decompose from approximately 151 °C (424 K) at 103 kPa. As a result, no value for the boiling point of the test item could be determined.

After heating to 400 °C, the samples had lost approximately 48 and 57 % of their original weight respectively.

 

The residues were a dark brown soft solid, some of which had erupted through the hole in the crucible lid.

 

Overall result: decomposition from approximately 151 °C (424 K)

Conclusions:
The test item has been determined to decompose from approximately 151 °C (424 K) at 103 kPa. As a result, no value for the boiling point of the test item could be determined.
Executive summary:

Boiling Point. Decomposition from approximately 151 °C (424 K) at 103 kPa by differential scanning calorimetry, 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 a result, no value for the boiling point of the test item could be determined.
