An olefin oxide is produced from an olefin in an electrolytic cell by mixing an aqueous electrolyte and liquid olefin under pressure, flowing the liquid mixture through a restricting device into the electrolytic bath of the cell to reduce the pressure of the mixture and to vaporize the olefin, and applying an electric current to the electrolyte/olefin mixture. The electrolyte includes a metal halide, a carbonate salt and a bicarbonate salt.

Process for preparing olefin oxides

A process and the product made thereby are disclosed in the preferred form of this process wherein a polymeric packing material is first fluorinated at ambient temperature for an interval of contact with elemental fluorine. Then, contact with a strong base converts the polymer into conjugated double bonds, reducing electrical resistance. The double bonds yield a surface layer able to controllably conduct electrical current.
