This method utilizes a novel solid catalyst made specifically for olefin epoxidation. The catalyst utilizes a base in order to allow hydrogen peroxide to be utilized as an oxidant.  Further the system allows for a constant flow of feedstock to flow through the catalyst with minimal leaching of the metal from the catalyst allowing for a longer life of the catalyst.
