- Executive summary:
In this study the boiling point of Tetrabutylphosphonium chloride was measured by DSC analysis. The test substance decomposes upon boiling at ca. 344.8 °C.
Reference
Two replicate DSC analyses were performed and provided the following results:
1: 340.4
2: 349.2
Mean value: 344.8
The shape of the DSC curves indicates that the substance has a boiling point and a decomposition simultaneously occurring. The endothermic peaks are broad with erratic behavior. This is an indication of onset of boil followed directly by decomposition. Decomposition is confirmed by analyzing the test substance at four different heating rates and observing a different onset each time. Boiling point is a first order reaction independent of heating rate. If the thermal event was a boiling point, the onset temperature would be consistent.
