Atmospheric pressure: Determinations 1 to 4: 103 kPa

Overall result: Test item showed a possible loss of volatiles at approximately 300 °C under a

nitrogen atmosphere and decomposition from approximately 300 °C under an air atmosphere.

Discussion

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

As a result of low enthalpy changes during the endotherm under nitrogen combined with the percentage weight loss of test item under the conditions the endotherm was assigned to possible loss of volatiles and not a boiling point. A visual assessment was carried out and after the test item melted there were no changes to the test item up to 300 °C.

Conclusion

The test item has been determined to decompose from approximately 300 °C (603 K) at 103 kPa, under an air atmosphere and possible lose volatiles at approximately 300 °C (603 K) at 103 kPa, under a nitrogen atmosphere. As the test item decomposed, no value for boiling point could be determined.

Description of key information

The test item has been determined to decompose from approximately 300 °C (603 K) at 103 kPa, under an air atmosphere and lose volatiles at approximately 300 °C (603 K) at 103 kPa, under a nitrogen atmosphere. As the test item decomposed, no value for boiling point could be determined. Determination by differential scanning calorimetry (Method A.2/OECD 103).
