An ion mobility and theoretical study of the thermal decomposition of the adduct formed between ethylene glycol dinitrate and chloride

•A dual ion shutter ion mobility spectrometer was used to obtain the kinetics for the thermal decomposition of EGDN·Cl− over the temperature range of 79–97°C.•The decomposition reaction of EGDN arises from the expulsion of an NO3 group by Cl.•The mobility peaks of NO3− and NO2− for the gas phase nitrate esters in the presence and absence of chloride dopant with different drift gas environments is discussed.
