Abstract: |
The mechanism of C3H7/NH2/Fe+ reaction system producing ethylene and propylene was studied using B3LYP density functional theory (DFT) in conjunction with the 6-31+ G basis set. The geometry, energy, and frequency of the reactants, intermediates, products, and transition states relevant to the reaction were located on the quartet potential energy surface of [Fe, C3, N, H9]+ . The data of the quartet potential energy surface of [Fe, C3, N, H9]+ and element steps of this reaction were obtained. |
