The alkali metals were electrodeposited from various solutions in propylene carbonate (PC). Li, Na, K, Rb, and Cs were electrodeposited from solutions of their chlorides and AlCl/sub 3/ in propylene carbonate (PC) at ambient temperature. In addition, lithium was deposited from LiCl, LiBr, LiClO/sub 4/, LiPF/sub 6/, and LiBF/sub 4/ solutions in PC. Sodium was reduced from NaClO/sub 4/, NaPF/sub 6/, and NaBF/sub 4/ solutions. Potassium was obtained from KPF/sub 6/ solution. A new process is proposed for the production and electrorefining of the alkali metals at ambient temperature. Alkali metal amalgam from the commercial mercury-chlorine cell is transferred into an AlCl/sub 3/-PC electrorefining cell, where the alkali metal is dissolved anodically from the amalgam, and deposited in a pure form at the cathode.
