Hydrochloric Acid and Lithium Hydroxide

概要

Hydrochloric acid reacts with lithium hydroxide to form lithium chloride and water. Lithium hydroxide is used as a CO₂ absorbent in spacecraft and submarines because it reacts with CO₂ more efficiently per unit mass than other alkali hydroxides, critical where weight is a constraint.

日常の例

Lithium hydroxide canisters in the Apollo spacecraft removed CO₂ from the cabin air, famously becoming critical during the Apollo 13 emergency.

産業上の重要性

水酸化リチウムは宇宙船・潜水艦のCO₂スクラビング、リチウム電池正極材製造（LiNiO₂系材料）に使われる。塩化リチウムは吸湿剤・乾燥剤として産業利用される。
