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

- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:

- Conclusions:
- The substance is a white powder at room temperature.
A test substance sample was observed to be a medium to fine white powder with clusters.
From observations using a 3.2 objective lens, the particles appeared to be irregular shaped crystals.
From observations using a 40 objective lens, the sample was observed to be made up of single crystalline particles.

- Conclusions:

- Executive summary:
Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200.
The melting temperature of the substance was determined to be in the range of 230.8°C - 235.1°C.
In the DCS experiments, reaction and/or decomposition of the substance was observed during and after melting, starting at approximately 230°C.
Three experiments were performed to investigate the melting and boiling behaviour of the substance.
DSC EXPERIMENT 1
An endothermic peak was observed between 200°C and 250°C followed by another endothermic effect starting at 250°C (see the illustration below). The extrapolated onset temperature of the first peak was 235.137°C. The first endothermic effect was most likely caused by melting of the test item. The second endothermic effect was probably caused by reaction and/or decomposition of the test item.
After the experiment, a dark molten residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item.
DSC EXPERIMENT 2
In order to investigate the melting peak, in Experiment 2 heating was stopped directly after the melting effect. The extrapolated onset temperature was 230.844°C. After the experiment, a light yellow molten residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test item.
DCS EXPERIMENT 3
The difference in the extrapolated onset temperature between Experiment 1 and 2 was >1°C. Therefore a third experiment was performed, applying the same heating rate as in experiments 1 and 2, and the same end temperature as in experiment 2.
The extrapolated onset temperature was 234.398°C. After the experiment, a light yellow molten residue remained in the container.
Experiment 3 thus confirmed melting of the test item, in combination with reaction and/or decomposition.
DATA HANDLING
The melting temperature is reported as a range because of the rather large variantion in values obtained in the three experiments. The variation is likely due to reaction and/or decomposition of the test item.
