FIELD: chemistry.

SUBSTANCE: invention relates to chemistry, specifically to the technology of producing a valuable semi-product - methyl chloride, which is a promising raw material for producing ethylene and other light olefins. Described is a method for selective catalytic oxychlorination of methane to methyl chloride, where a mixture consisting of methane, hydrogen chloride and either oxygen diluted with an inert gas, or air or pure oxygen is passed at temperature not higher than 350°C through a catalyst layer which is a geometrically structured system which contains microfibres of a high-silica support and at least one active element, said element being either in form of a MeO_xHal_y composite or in form of a N_wMe_zO_xHal_y composite, where element Me is selected from a group comprising iron, cobalt, nickel, ruthenium, rhodium, vanadium, chromium, manganese, zinc, copper, silver, gold or one element from a group of lanthanum and lanthanides, and element Hal is one of halogens: fluorine, chlorine, bromine, iodine and element N in composite N_wMe_zO_xHal_y is selected from a group comprising alkali, alkali-earth elements or hydrogen.

EFFECT: high degree of conversion of initial reagents and selectivity of formation of methylchloride.
