FIELD: chemistry.
SUBSTANCE: present invention refers to the variants of methods for preparation of the hydrocarbons with number of the carbon atoms in the chain Cn whereat n≥2 and n≤20. The said method includes the formation of the halogenated hydrocarbon in the reaction of the hydrocarbon reagent with number of the carbon atoms in the chain Cm whereat m<n, m≥1 and m≤10 with halogenating agent; formation of the hydrocarbon product with number of the carbon atoms in the chain Cn whereat n≥2 and n≤20 at the contact of the halogenated hydrocarbon with catalytic reagent of metal oxide; separation of the hydrocarbon product and regeneration of the catalytic reagent.
EFFECT: avoiding of the recyclisation and separation of the water solution of hydrohalic acid.
