Process for producing anhydrous alkali sulfide

摘要

An object of the present invention is to provide a method of obtaining anhydrous alkali sulfites which are useful as synthetic intermediates in a simple manner without treatment at ultra low temperatures, high temperatures or high pressure. <??>According to the present invention, anhydrous alkali sulfides are obtained by reacting sulfur with an alkali metal other than lithium in the presence of an aprotic solvent.
