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): [LMnX3]Y, or a binuclear species of the general formula (II): [LMn(μ-X)3MnL]Yn, 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 μ-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.
本发明涉及一种生产环氧乙基羧酸酯或环氧丙基羧酸酯的方法,包括在水相反应介质中使用氧化剂和水溶性锰配合物反应乙烯基羧酸酯或烯丙基羧酸酯,其中水溶性锰配合物包括氧化催化剂,其特征在于所述水溶性锰配合物是通式(I)的单核物种:[LMnX3]Y,或通式(II)的双核物种:[LMn(μ-X)3MnL]Yn,其中Mn是锰,L是配体,每个L独立地是多齿配体,每个X独立地是配位物种,每个μ-X独立地是桥联配位物种,Y是非配位的反离子,环氧化反应在pH为1.0至7.0的范围内进行。
