- Specific details on test material used for the study:
- PROCEDURE
- Sample:
Aliquots (0.0056 g and 0.0066 g) of test material were placed in aluminium crucibles, which had been
scratched with a needle to aid crystallisation.
- Analysis:
The DSC parameters were as follows:
Calorimeter: Mettler Toledo DSC822e
ThermoHaake Cooler EK45/MT
Temperature program:
* initial: 25.0°C
* rate: 20.0°C/min
* final: 400.0°C
Atmosphere: air (static)
The temperature accuracy of the DSC was assessed using an indium reference standard (purity*99.999%). The melting temperature was determined to be 156.7°C and within the defined tolerance (156.6 ± 0.5°C). The DSC was therefore considered acceptable for use.
- Calculation:
Measured temperatures were converted from °C to K using the following equation:
T = t + 273.15
where T = temperature (K) and t = temperature (°C) - Key result
- Boiling pt.:
- 211.61 °C
- Atm. press.:
- 101.92 kPa
- Conclusions:
- The boiling temperature of the test material has been determined to be 485 ± 0.5 Kat 101.92 kPa.
- Executive summary:
The determination of the boiling point of Monofluoroethylene carbonate was performed by differential scanning calorimetry (DSC) according to ASTM E537 -86, OECD Guideline n°103 and EU Method A.2, under GLP conditions. The result was: 211.61°C at 101.92 kPa.
