- Conclusions:
- The melting point of cC6O4 ammonium salt was determined to be 64.6 °C, which is equal to 337.8 K.
The estimated accuracy is ± 0.5 K. - Executive summary:
The determination of the melting point/melting range of the test item was performed according
to the EEC Directive 92/69 and Council Regulation (EC) No. 440/2008, A.1 “Melting/Freezing
temperature“ and to the OECD Guideline No. 102: “Melting point / melting range“, adopted July
27, 1995.
The melting point of cC6O4 ammonium salt was determined to be 64.6 °C, which is equal to 337.8 K. This result was obtained at the onset of the endothermic peak using Differential Scanning Calorimetry (Thermal Analysis) method.
Reference
Preliminary Test
The DSC-curve of the preliminary test (heating rate of 20 °C/min from 25 °C to 400 °C) is
shown in Figure 1. An endothermic heat effect started at 63.3 °C, an exothermic reaction
followed at about 221 °C. After the experiment, the sample had lost about 96% of its mass and a
brown residue remained
Main Test
In order to determine the melting more precisely, further DSC-runs were recorded between 25 °C
and 100 °C with a heating rate of 10 °C/min. In the first main test run, the melting (measured as
the onset of the endothermic peak) was observed at 64.4 °C, during the second main test run at
64.8 °C. During these runs, the sample lost no weight and a milky melt remained.
Description of key information
The determination of the melting point/melting range of the test item
was performed according to the EEC Directive 92/69 and Council
Regulation (EC) No. 440/2008, A.1 “Melting/Freezing temperature“ and to
the OECD Guideline No. 102: “Melting point / melting range“, using a
differential scanning calometry (thermal analysis).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 64.6 °C
