Electrodeposition of the alkali metals from propylene carbonate
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.
