METHOD OF PRODUCING EPICHLOROHYDRIN USING HYDROGEN PEROXIDE AND MANGANESE COMPLEX Russian patent published in 2013 - IPC C07D303/08 C07D301/03 C07D301/12 

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): [LMnX₃]Y (1) or a binuclear manganese complex of general formula (II): [LMn(|µ-X)₃MnL]Y₂ (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^-, N₃ ^-, I₃ ^-, NH₃, NR₃, RCOO^-, RSO₃ ^-, RSO₄ ^-, OH^-, O^2-, O₂ ^2-, HOO-, H₂O, SH^-, CN^-, OCN^-, and S₄ ^2- combinations thereof, where R is a C₁-C₂₀ radical 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.
