| Abstract: | Phenylethane was oxidized directly to hypnone and α-phenyethanol with air under the catalysis of μ-oxo-bis-iron porphyrin of products at alpha position is 100%.The reaction temperature and time have influences on the yield and the selectivity of products.With the reaction time extending,the yield of products increased,but the selectivity of hypnone slightly increased and the selectivity of α-phenyethanol slightly descended.With the temperature raising,the selectivity of hypnone descended and the selectivity of α-phenyethanol increased. |
