Abstract
The selectivity of an olefin epoxidation catalized by a noble metal-modified titanium or vanadium zeolite is greatly enhanced by the addition of a phosphorus, sulfur, selenium or arsenic compound to the reaction mixture. The epoxidation utilizes hydrogen and oxygen in addition to the olefin.
