The invention relates to a process for the manufacture of an epoxyethyl carboxylate or glycidyl carboxylate, including reacting a vinyl carboxylate or an allyl carboxylate using an oxidant and a water-soluble manganese complex in an aqueous reaction medium, and the water-soluble manganese complex comprises an oxidation catalyst, characterized in that the water-soluble manganese complex is a mononuclear species of the general formula (I) [LMnX]Y (I), or a binuclear species of the general formula (II): [LMn(&#x3bc;-X)MnL]Y(II), wherein Mn is a manganese; L is a ligand and each L is independently a polydentate ligand, each X is independently a coordinating species and each &#x3bc;-X is independently a bridging coordinating species, Y is a non-coordinating counter ion, and wherein the epoxidation is carried out at a pH in the range of from 1.0 to 7.0.

Manufacture of an epoxyethyl carboxylate or glycidyl carboxylate

Processes are provided for the formation of an epoxyethyl ether or a glycidyl ether. In one embodiment, a process is provided for the manufacture of an epoxyethyl ether or glycidyl ether including reacting a vinyl ether or an allyl ether with an oxidant in the presence of a water-soluble manganese complex in an aqueous reaction medium, wherein the water-soluble manganese complex comprises an oxidation catalyst, characterized in that the water-soluble manganese complex is a mononuclear complex of the general formula (I): [LMnX]Y (I), or a binuclear complex of the general formula (II): [LMn(&#x3bc;-X)MnL](Y)(II), wherein Mn is a manganese; L or each L independently is a polydentate ligand, each X independently is a coordinating species and each &#x3bc;-X independently is a bridging coordinating species, Y is a non-coordinating counter ion, and wherein the epoxidation is carried out at a pH in the range of fromto. The invention also relates to epoxyethyl ethers.

Manufacture of an epoxyethyl ethers or glycidyl ethers

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.

Epoxidation process

A process for the manufacture of propylene oxide ('PO') by catalytic oxidation of propylene with an oxidant wherein the catalytic oxidation is performed in an aqueous reaction medium, comprising water with less than 10% by volume of cosolvents, wherein a water-soluble manganese complex is used as oxidation catalyst, characterized in that the water-soluble manganese complex is a mononuclear species of the general formula (I):[LMnX]Y &#x2003;&#x2003;(I)or a binuclear species of the general formula (II):[LMn(&#x3bc;-X)MnL]Y&#x2003;&#x2003;(II)wherein Mn is a manganese; L or each L independently is a polydentate ligand, each X independently is a coordinating species and each &#x3bc;-X independently is a bridging coordinating species, whereas Y is an non-coordinating counterion, and wherein the catalytic oxidation is carried out at a pH in the range of from 1.5 to 6.0.
