The first increase of temperature during DSC
experiment showed an endotherm of 126 J/g starting from 257°C, which is
related to the sample melting. No exotherm was detected in the range
25°C – 400°C. The second temperature raise after cooling the sample
confirms these results (black curve). An endotherm of 84 J/g is
observed, starting from 253 °C. No exotherm was noticed. The difference
between the measured values for the melting is due to the thermal
history of the sample which is erased after the sample cooling. This
cooling (blue curve) from 400°C to 25°C shows a crystallization whose
order of magnitude (-87 J/g) confirms the 84 J/g observed for the
melting point of sodium
(NaTFSI) was determined under the ISO-9001:2015 Standard, using the
differential scanning calorimetry method. The test item was loaded at
room temperature in the DSC test cell under nitrogen atmosphere in a
glove box in order to ensure a low humidity. The stainless steel
crucible was sealed under nitrogen atmosphere. The temperature was
increased from 25 to 400°C at 2°C/min. In this range of
temperature no exotherm was detected. Under
these conditions the melting of NATFSI can be observed at a temperature
of 253°C (Tonset).
Sodium Bis(trifluoromethanesulfonyl)imide will melt at a temperature of 253°C (T-onset).
One reliable key study is available for this
endpoint. In this study the melting point of Sodium
Bis(trifluoromethanesulfonyl)imide has been measured by differential
scanning calorimetry method.
