- Decomposition:
- yes
- Decomp. temp.:
- ca. 117.35 °C
- Remarks on result:
- not determinable
- Remarks:
- The boiling point could not be determined due to decomposition of the substance starting at 117.35 °C.
- Conclusions:
- The onset temperature of the first endothermic event, associated with decomposition, was found being 117.35 ±0.6 °C.
- Executive summary:
The determination of boiling point of AM(pfa)4 was determined via DSC (differential scanning calorimetry). Three DSC measurements were performed and in all measurements two endothermic events and one small flat exothermic event were detected. According to the observations of the pre-test, these events could be an indication of the splitting of a chemical compound.
The first endothermic event matches the observation of the pre-test, where condensate with steam was first seen in the test tube. The second endothermic event could correspond to the surface boiling seen in the pre-test. The exothermic event could correspond to the phase where clumping and discoloration were seen. Hence, no boiling of the test item was observed. Therefore, no boiling point can be determined under these circumstances.

Results from Pre-test following Siwoloboff
All observations of the Pre-test following Siwoloboff are presented in the following table:
Table 1: Pre-test following Siwoloboff
Observations | Temperatures in °C |
Colorless condensate was visible | Since 120 |
Condensate at the surface boiled with steam vortex in test tube, the surface was wet and shrivelled | Since 160 |
steam came out from the test tube, steam vortex was still visible | Since 180 |
The upper part (the half amount of the test item) was slightly shrivelled | Since 240 |
Condensate dropped and fizzed, condensate boiled on the wall of the test tube no more liquid on the surface but steam vortex | Since 275 |
Less condensate and steam | Since 330 |
No more condensate only a little steam, the test item was slight darker and no more shrivelled | Since 370 |
Gas burner was turned off | 400 |
After cooling down the test item was still solid but getting brownish (beige) and was compacted again, no more shrivelled. The amount of the test item had decreased, and decomposition was considered.
Security Pre-test for the DSC instrument
The crucible was found visually unchanged after reaching a temperature of 450 °C. The weight of the crucible was recorded with 45.04 mg (47.56 mg before experiment).
Calibration of DSC instrument: After calibration with indium and zinc the measurement of indium yielded the following values:
Table 2: Pre-test following Siwoloboff
ExpectedMelting point | Measured Melting point | Expected Energy | Measured Energy | Assessment |
156.6 ± 1.0°C | 156.62 °C (onset) | 28.45 ± 1.0 J/g | 28.36 J/g | OK |
The measurement of indium after calibration met the validity criteria.
DSC Measurement of the Test Item: Three determinations were performed and the results are reported in the following table:
Table 3: DSCValues and observations
Mass test item | Mass crucible (before measurement): | Mass crucible (after measurement): | Observations | |
First Measurement | 2.65mg | 47.40mg | 45.02 mg | After the test the crucible was visually unchanged The crucible was opened, a few test item was remained as a white solid (slightly shrivelled white powder) |
Second Measurement | 2.61mg | 47.06 mg | 44.83 mg | After the test the crucible was visually unchanged |
Third Measurement | 2.72mg | 47.39 mg | 45.10 mg | After the test the crucible was visually unchanged. |
Interpretation of the measurements
Three DSC measurements were performed. In all measurements two endothermic events and one small flat exothermic event were detected.
According to the observations of the pre-test, these events could be an indication of the splitting of a chemical compound. The first endothermic event matches the observation of the pre-test, where condensate with steam was first seen in the test tube. The second endothermic event could correspond to the surface boiling seen in the pre-test. The exothermic event could correspond to the phase where clumping and discoloration were seen. Therefore, no boiling point can be determined under these circumstances.
Validity: Calibration (see above) was valid, but as no boiling point could be determined, no validity needs to be considered.
The determination of boiling point of AM(pfa)4 was determined via DSC (differential scanning calorimetry). Three DSC measurements were performed. In all measurements two endothermic events and one small flat exothermic event were detected. According to the observations of the pre-test, these events could be an indication of the splitting of a chemical compound. No boiling of the test item was observed. Therefore, no boiling point can be determined under these circumstances.
The onset temperature of the first endothermic event, associated with decomposition, resulting as mean from three experiments was found being 117.35 ±0.6 °C, considered as decomposition temperature of the substance.
No observations were made which might cause doubts on the validity of the study out-come. Therefore, the result of the study is considered valid.
