Flash point

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

the study does not need to be conducted because decomposition occurred during the melting point study

Results

For the thermograms and thermographic data for Determinations 1 and 2, kindly refer the attached background material section of the IUCLID.

Thermographic Data

Thermal Event	Interpretation	Temperature (°C)
		Determination 1	Determination 2
Exotherm	Onset of decomposition	279.55	281.00

Atmospheric pressure:  100 kPa

After heating to 400 °C, the samples had lost approximately 88% and 81% of their original weight for Determinations 1 and 2 respectively.

Boiling temperature: decomposition from approximately 280°C (553 K)

Discussion

The test substance softened gradually over a broad temperature range with apparently 3 or 4 observable phases in the thermograms. This may have been due to not only the test substance being a mixture of components, but also components having different organic functional groups. Therefore, each component or group of components could have their own melting temperature resulting in the test substance not completely melting until 121 °C. This effect resulted in the test substance gradually softening rather than a sudden complete melt over a short temperature range. As a result of the low rate of enthalpy change during decomposition, the onset temperature could only be approximated.

Conclusion

The test substance has been determined to decompose from approximately 280 °C (553 K) at 100 kPa. As the test substance decomposed, no value for boiling temperature could be determined.

Conclusions:

Under the study conditions, the test substance has been determined to decompose from approximately 280°C at 100 kPa. As the test substance decomposed, no value for boiling temperature could be determined.

Executive summary:

A study was conducted to determine the boiling point of test substance using the differential scanning calorimetry method, according to OECD Guideline 103. Under the study conditions, the test substance has been determined to decompose from approximately 280°C at 100 kPa. As the test substance decomposed, no value for boiling temperature could be determined (Envigo, 2019).
