<p>PROBLEM TO BE SOLVED: To inexpensively and efficiency decompose a gaseous halogenated hydrocarbon or a gas containing the same by introducing the gaseous halogenated hydrocarbon or the gas containing the same in a closed vessel housing a solution or a suspension of an alkaline material while pressurizing, and treating it at a specific temp. SOLUTION: In the decomposition of the gaseous halogenerated hydrocarbon such as methyl chloride by-produced by various reactions and harmful to human body or the gas containing the same, the gaseous halogenated hydrocarbon or the gas containing the same is introduced into the closed vessel housing the solution or the suspension of the alkaline material while being pressurized in the condition of >=1kd/cm<2> G (20 deg.C), and treated at 20-100 deg.C. As the solution of the alkaline material, usually an aq. solution of the hydroxide of an alkali metal or an alkaline earth metal is suitably used and sodium hydroxide is preferably used, and as the suspension of the alkaline material, an aq. suspension of a regenerative type strong basic anion exchange resin is suitably used.</p> |
