Hydrogen Abstraction Reactions by NH₂(X²B₁)‐Radicals from Hydrocarbons in the Gas Phase

Abstract

Abstract The NH 2 (X̃ 2 B 1 ) 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 [cm 3 mol −1 s −1 and E A in [kJ mol −1 ]: A correlation between the Arrhenius activation energy and the energy of the broken CH bond is discussed.
