- Conclusions:
- EC# 915-640-4 was found to partially melt at temperatures above approximately 100°C, before decomposing from approximately 220°C.
- Executive summary:
The melting temperature was determined using the metal block method. The melting temperature of a substance is defined as the temperature (°C) at which the phase
transition from solid to liquid state at normal atmospheric pressure takes place. Dry test item was tightly packed into a capillary tube to a height of 3 mm. In an initial
estimation of melting point, the capillary tube was placed in the apparatus and heated at 10°C/minute up to 360°C.
The test item showed the initial stages of melting from approximately 100°C, but did not melt completely. At approximately 245°C, evolution of gas from the partially molten sample was observed to force the sample up the capillary tube, indicating decomposition. The sample continued to gradually darken from this point.
For confirmatory purposes, differential scanning calorimetry (DSC) was also conducted using a Mettler-Toledo FP900 Thermosystem with FP85 DTA/DSC measuring cell, in an air atmosphere at a heating rate of 5°C/minute. The DSC trace showed a broad shallow endotherm below 150°C, followed by significant exotherms from approximately 220˚C which were consistent with the indication of decomposition in the metal block test.
EC# 915-640-4 was found to partially melt at temperatures above approximately 100°C, before decomposing from approximately 220°C.
