FIELD: chemistry.SUBSTANCE: invention relates to a method of producing epichlorohydrin which is used as a solvent for cellulose, resins and dyes, as fumigant and as a structural unit when producing plastic, epoxy resins and phenol resins. The method involves reaction of allyl chloride with an oxidant in the presence of a catalyst which contains a water-soluble manganese complex in an aqueous reaction medium with molar ratio of allyl chloride to the oxidant ranging from 1:0.1 to 1:1.2, followed by removal of the epichlorohydrin product. Normally the catalyst contains a mononuclear manganese complex of general formula (I): [LMnX]Y (1) or a binuclear manganese complex of general formula (II): [LMn(|µ-X)MnL]Y(II), where Mn is manganese; L or each L independently denotes a polydentate ligand; each X independently denotes coordination compounds and each µ-X independently denotes bridge coordination compounds selected from a group consisting of: RO, Cl, Br, I, F, NCS, N?, I?, NH, NR, RCOO, RSO?, RSO?, OH, O, O?, HOO-, HO, SH, CN, OCN, and S?combinations thereof, where R is a C-Cradical selected from a group consisting of alkyl, cycloalkyl, aryl, benzyl and combinations thereof, and Y denotes an oxidation-stable counter-ion.EFFECT: method enables to carry out the process with high selectivity and number of rotations.15 cl, 4 ex, 3 tbl |
