Abstract

A process of producing alkali metal by a reduction of alkali metal compounds with metallic reducing agents, which is simplified and avoids corrosion of the reaction vessel and part thereof in that the reduction is effected with particulate magnesium in an organic solvent which under the conditions of the process is inert to the alkali metal to be produced. The reaction is effected at temperatures from 100.degree. to 300.degree. C. In an embodiment of the process the reduction is effected in the presence of an alcohol used as a reaction accelerator.
