Tóm tắt

AbstractThe NH2(X̃2B1) radical reactions with saturated hydrocarbons, toluene and acetaldehyde were investigated in an isothermal discharge flow system over the given temperature ranges. The pressure was varied between 2.6 and 7.8 mbar. Helium was used as the main carrier gas. The temperature dependences of the rates are represented by the following Arrhenius expressions, with A in [cm3 mol−1 s−1 and EA in [kJ mol−1]: A correlation between the Arrhenius activation energy and the energy of the broken CH bond is discussed.
