Reference
Preliminary thermogravimetric measurement:
Beginning at room temperature the mass loss rate increased steadily, reaching a maximum at 188 °C. At approx. 200 °C the mass loss was practically complete, considering the initial mass loss from purging (0.2 %) before the start of the measurement. There was no residue left.
DSC measurements:
The heat flow curve shows two sharp endothermic peaks the second one with a peak maximum temperature at 228/227 °C and an extrapolated onset temperature of 223/223 °C, indicating the boiling temperature at ambient pressure. Reweighing after the measurement the sample had lost 100 % of its mass.
