Summary:PROBLEM TO BE SOLVED: To provide a method for producing a particulate, high purity anhydrous alkali metal sulfide at high productivity.SOLUTION: Provided is a method for producing an anhydrous alkali metal sulfide containing a process where a hydrous alkali metal sulfide is irradiated with microwaves in the presence of an organic solvent dissolved with water such as alcohol. More concretely, provided is a method for producing an anhydrous alkali metal sulfide where a hydrous alkali metal sulfide included in an alkali metal sulfide aqueous solution prepared by an alkali metal hydrosulfide and an alkali metal hydroxide is irradiated with microwaves in the presence of an organic solvent dissolved with water.SELECTED DRAWING: None 【課題】 微粒子状の高純度の無水アルカリ金属硫化物を生産性良く製造する方法を提供すること。【解決手段】 アルコール等の水と溶解する有機溶媒の存在下で、含水アルカリ金属硫化物にマイクロ波照射する工程を有することを特徴とする無水アルカリ金属硫化物の製造方法を提供する。さらに詳しくは、アルカリ金属水硫化物及びアルカリ金属水酸化物より調製されたアルカリ金属硫化物水溶液中に含まれる含水アルカリ金属硫化物に、水と溶解する有機溶媒の存在下で、マイクロ波照射する無水アルカリ金属硫化物の製造方法を提供する。【選択図】 なし
