A reaction system for epoxidation of olefins, with a feed control system configured to control the relative quantity of reaction modifier present in the feed, where the relative quantity of said reaction modifier is changed in response to changes in the reaction temperature.

Process and systems for the epoxidation of an olefin

A process for the epoxidation of an olefin, which process comprises reacting a feed comprising the olefin, oxygen and a reaction modifier in the presence of a highly selective silver-based catalyst at a reaction temperature T, and with the reaction modifier being present in a relative quantity Q which is the ratio of an effective molar quantity of active species of the reaction modifier present in the feed to an effective molar quantity of hydrocarbons present in the feed, and which process comprises the steps of:
