The new NaY zeolite (DMY). whose cages’ size had been expanded, was used as supports for encapsulating the large Schiff-base complexes. The catalysts were used in the aerobic epoxidation of 1-octene. The catalyst showed high activity and selectivity for the substrate and products. These catalysts proved to be more active than other kind of metal ion or supports. The effect of temperature, organic acid or base, and the amount of catalyst was discussed.
