After heating to 400 °C, the samples had lost approximately 64% of their original weight.
Overall result: decomposition from approximately 155 °C (428 K)
As a result of the low rate of enthalpy change during decomposition, the onset temperature could only be approximated. Two further thermograms were run for additional information. These showed that after being heated to 150 °C and 300 °C they had lost none and 7% of their original weight respectively. The appearance of the residue after being heated to 150 °C was similar to that of the original test item; this also suggested that decomposition had not occurred up to 150 °C.
Applicant's summary and conclusion
- Conclusions:
- The test item has been determined to decompose from approximately 155 °C (428 K) at 101 kPa. As the test item decomposed, no value for boiling temperature could be determined.
- Executive summary:
Decomposition from approximately 155 °C (428 K) at 101 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 the test item decomposed, no value for boiling temperature could be determined.
