ABSTRACT:
Disclosed herein is an improved gas phase process for the selective epoxidation of non-allylic olefins wherein the epoxidation is carried out in the presence of certain inert, paraffin hydrocarbons. Such hydrocarbons possess higher heat capacities as compared to other materials, e.g., nitrogen, argon, methane and helium, typically used as inert diluents in olefin epoxidations. The disclosed process is particularly useful for the continuous manufacture of 3,4-epoxy-1-butene from 1,3-butadiene.
