Clean Oxidation Technologies New Prospects in the Epoxidation of Olefins... 

Whereas such applications of catalytic clean-up technology are of obvious importance, it is even more desirable to develop new catalytic processes that produce less or no waste products. Many conventional routes consume acids or bases and produce salts which cause waste problems. The production of ethylene epoxide from ethylene by direct oxidation over silver catalysts forms an example for a clean, catalytic process which has replaced traditional routes involving the... 

Despite the above drawbacks, metal-peroxo chemistry will have an increasing contribution to clean industrial epoxidations. One of the current technologies used for propylene oxide and epichlorhydrin is the chlorhydrin route, where olefin is reacted with hypochlorous acid (from chlorine) followed by ring-closure of the chlorhydrin with lime ...
