Any other information on results incl. tables
Two samples of approximately 10 - 11 mg of test material, sealed in aluminium crucibles with a micro pin hole in the lid, were heated at 10 K.min-1 in a Mettler DSC821e from 25 - 450°C under a nitrogen purge (75 ml.min-1).
In both scans, a broad endothermic peak was observed at a peak temperature of ca. 135°C, followed by a large and vigorous exotherm at a peak temperature of ca. 420°C. It is known from information provided by the Sponsor that the endothermic peak is not associated with melting, as the test substance has been shown not to melt below 310°C. The exothermic peak
suggests that decomposition has occurred, which was confirmed by examination of the samples after cooling, revealing the presence of a residue of 61 - 62% of the original mass. No endothermic peak indicative of boiling was observed.
Applicant's summary and conclusion
- Conclusions:
- The test substance decomposes without boiling.
- Executive summary:
Introduction
The boiling point was measured by DSC, which is an approved method for Test A2.
The heat flow to the sample is measured as it is heated at a constant rate in a sealed crucible which, for a boiling point determination, must have a very small pin hole in the lid. As the boiling point is approached, the heat flow begins to increase as the sample evaporates through the pin hole. Once the sample boils, its temperature remains constant and the furnace temperature moves ahead of that of the sample at a constant rate, causing the heat flow profile to have a linear portion before it again subsides once the sample has boiled away. The temperature at the linear portion of the DSC thermogram is the boiling point.
