Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for the manufacture of an epoxide, comprising: forming an aqueous phase comprising a water-soluble catalyst and oxidant in a reactor; providing a terminal olefin having a water solubility ranging from 0.01 g/L to 100 g/L in an amount sufficient to form an organic phase at a volumetric ratio of the aqueous phase to the organic phase from 10:1 to 1:5; dispersing the organic phase into aqueous phase to form organic phase droplets having an average…
