Abstract

Apparatus and processes are provided for forming epoxide compounds. In one embodiment, a process for the manufacture of an epoxide is provided including adding an oxidant, a water-soluble manganese complex and a terminal olefin to form a multiphasic reaction mixture, reacting the terminal olefin with the oxidant in the multiphasic reaction mixture having at least one organic phase in the presence of the water-soluble manganese complex, separating the reaction mixture into the at least one organic phase and an aqueous phase, and reusing at least part of the aqueous phase. The invention is also related to a device for performing the above process.
