Remarks on result:
other: no data was provided

Melting Point/Melting Range: Two further DSC runs were performed in the temperature range between 25°C and 170°C with a heating rate of 5°C/min to determine the melting range of FP-100. In the first main test run a first small endothermic heat effect started at 60.9°C followed by a second endothermic peak at 105.2°C. The same result was obtained during the second main test run with a first endothermic peak at 61.4°C and a second peak at 109.0°C. After the experiments the sample did not loose any weight and a colourless clear liquid remained.

Conclusions:
The aim of this study was to determine the melting and the boiling point/range of FP-100.

Melting Range: The melting range of FP-1 00 was determined to be from 61.2°C to 107.1°C which is equal to 334.4K to 380.3K.
