Abstract
Olefins are epoxidized by hydrogen peroxide in the presence of a modified titanium-containing molecular sieve having a framework structure isomorphous with zeolite beta and comprised of Si, Ti, and Al. The molecular sieve is modified by substituting the aluminum-associated cationic sites with ammonium, alkali metal, or alkaline earth cations instead of protons.
