Additional information

Decomposition of the substance in the presence of air starts at 229 ºC. Several studies done with or without the presence of air with the identical structural formula with Sodium as counter ion are available.

Testing results obtained in the same conditions are comparable (229ºC, 165º, 255º), nevertheless when testing is done without the presence of air, decomposition stars later, at 335ºC and 350ºC, with no melting before decomposition.
