Abstract

A method for the epoxidation of an olefin comprising the steps of reacting a feed gas composition containing an olefin oxygen and a moderator having an optimal moderator concentration in the presence of an epoxidation catalyst at a first temperature and having a first selectivity; and increasing the optimal moderator concentration to a second moderator concentration and whereby the first selectivity is lowed to a second selectivity and the first temperature to a second temperature.
