Popis: |
Active sites in titanium silicalite (TS-1) for selective oxidation of ethylene with H 2 O 2 were studied by using ab initio quantum chemical methods. Models of the active sites were energy optimised and the interaction with H 2 O and H 2 O 2 calculated. The binding situation of the resulting titanium hydroperoxo compounds were explained and transition states and activation energy for the epoxidation of ethylene were computed. The transition states were characterised by calculating the vibrational frequencies. |
