    Abstract: 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.
