Castner process

Japanese: カストナー法 - カストナーほう(英語表記)Castner process
Castner process
A method for producing metallic sodium invented by H. Kastner in 1886. Sodium hydroxide (caustic soda) is melted at about 340°C and electrolyzed to produce sodium and hydrogen in the cathode chamber and oxygen in the anode chamber. Although it has the advantage of a low operating temperature, it has a low current efficiency (about 40%) and is not widely used today. There is also Kastner's salt water electrolysis method, but the Kastner method refers to the former. (→Downs process)

1886年に H.カストナーが考案した金属ナトリウム製造法。水酸化ナトリウム (カセイソーダ) を約 340℃で溶融して電気分解すると,陰極室でナトリウムと水素,陽極室で酸素を生成する。操作温度の低い利点はあるが,電流効率が低く (約 40%) ,現在はあまり採用されていない。カストナーの食塩水電解法もあるが,カストナー法といえば前者をさす。 (→ダウンズ法 )
