Process for the manufacture of a 1,2-epoxide and a device for carrying out said process

摘要

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.

主权项

1. A process for the manufacture of an epoxide, comprising:
a) adding an oxidant, a water-soluble manganese complex, and a terminal olefin to form a multiphasic reaction mixture comprising at least one organic phase and an aqueous phase, wherein the water-soluble manganese complex is a mononuclear species of the general formula (I):
[LMnX3]Y  (I)  or a binuclear species of the general formula (II):
[LMn(μ−X)3MnL](Y)n  (II)  wherein Mn is a manganese; L or each L independently is a polydentate ligand, each X independently is a coordinating species and each μ−X independently is a bridging coordinating species, and wherein Y is a non-coordinating counter ion; b) 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; c) separating the at least one organic phase and the aqueous phase, wherein the aqueous phase comprises the water-soluble manganese complex; and d) reusing at least part of the aqueous phase.
