Endpoint:
flash point of flammable liquids
Data waiving:
study scientifically not necessary / other information available
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

Atm. press.:
ca. 1 atm
Decomposition:
yes
Decomp. temp.:
ca. 179.9 °C

Pre-Test

Begin of changes was visible at 192.7 °C (getting darker). The test substance was completely black at 195.3 °C. The last changes were nearly explosively.Decomposition was stated.

Main Study

The following values were recorded:

Values Main Study

Decomposition

Begin

End

First determination

180.0 °C (453.2 K)

182.2 °C (455.4 K)

Second determination

179.9 °C (453.1 K)

181.7 °C (454.9 K)

Validity

As the test substance decomposes no validity criteria must be considered.

Result

The determination was performed in duplicate. In both determinations, no melting point could be detected, because of decomposition of the test substance.

 

Beginning decomposition was determined with

 179.9 °C (453.1 K)

 Signs for explosive properties were visible.

Conclusions:
The determination was performed in duplicate. In both determinations, no melting point could be detected, because of decomposition of the test substance. Beginning decomposition was determined with 179.9 °C (453.1 K). Signs for explosive properties were visible.
Executive summary:

The melting point of the test item was investigated with a not-GLP compliant study, following the standard guideline OECD TG 102 (capillary method). The determination was performed in duplicate. In both determinations, no melting point could be detected, because of decomposition of the test item. Beginning decomposition was determined with 179.9 °C (453.1 K). Signs for explosive properties were visible.
