Thermal desorption mass spectroscopy TDMS

Awad et al. [56] reported on the thermal degradation of a series of alkylimidazolium molten salts. Elemental analysis, TGA, and thermal desorption mass spectroscopy (TDMS) were used to characterize the degradation process. A correlation was observed between the chain lengths of the alkyl groups and the thermo-oxidative stability as the chain length increased from propyl, butyl, decyl, hexadecyl, and octadecyl to eicosyl, the stability decreased. Analysis of the decomposition products by FTIR provided information about the decomposition products. It suggested that the thermal decomposition of imidazolium salts followed an SN2 process (Figure 3.12).
