Methods and compositions are provided for the manufacture of an epoxide. In one embodiment, the invention provides a process for the manufacture of an epoxide including providing an olefin, an oxidant, alkaline earth metal ions, a catalyst component, a buffer component, and water to form a reaction mixture and reacting the olefin with the oxidant in the reaction mixture.

Catalytic epoxidation process

Apparatus and methods are provided for forming and processing multiphasic systems. In one embodiment, the invention provides a process for the manufacture of an epoxide, including reacting an olefinically unsaturated compound with an oxidant in the presence of a buffer component and a water-soluble manganese complex disposed in an aqueous phase having a first pH level in a first multiphasic system, adjusting the pH of the aqueous phase to a second pH level less than the first pH level, isolating at least a portion of the aqueous phase from the first multiphasic system, adjusting the pH of the at least a portion of the aqueous phase to a third pH level greater than the second pH level, and introducing the at least a portion of the aqueous phase into a second multiphasic system.

Apparatus and methods to preserve catalyst activity in an epoxidation process

Processes and compositions are provided for epoxidizing an olefinically unsaturated compound. In one embodiment, a process is provided for reacting an olefinically unsaturated compound with an oxidant in the presence of a catalyst at acidic conditions, wherein the catalyst is activated prior to the reaction at a pH that is higher than the pH during the reaction.
