摘要： The present invention relates to a method for preparing chlorinated compounds from saturated hydrocarbon. More particularly, the present invention relates to the method for preparing chlorinated compounds by conducting alternately an oxidation reaction of a catalyst under oxygen and hydrogen chloride, and a chlorination reaction for converting the saturated hydrocarbon into the chlorinated compounds by using the catalyst. The present invention has the advantages that the conversion rate of the saturated hydrocarbon may be enhanced; there is no need to consider erexplosion hazards; unreacted hydrogen chloride and corrosion of reactor may be reduced; a separate device for separating COx in exhaust gases may not be required since CO or CO2 is not produced in a combustion reaction; by-product may not be generated; and the durability of a catalyst may be remarkably enhanced.
