| 外観 | 白色, 結晶～結晶性粉末 | | 溶解性 | 水に可溶 (12.7g/100g水, 0℃)。アルコールに難溶。水に溶けやすく、エタノールに溶けにくい。 | | 用途 | 農薬(殺菌剤)、農薬原料、医薬、防腐剤、化学繊維製造凝固剤、メッキ、蛍光隊原料、飼料添加物 | | 効能 | 躁病薬 | | 使用 | Used in catalyst for alkyd resins. | | 使用 | Lithium hydroxide monohydrate is used for the production of lithium greases, lithium soaps, lithium stearate and lithium salts. It finds application as a carbon dioxide adsorbent in breathing gas purification systems for spacecrafts, submarines and rebreathers; as a storage-battery electrolyte; as a heat transfer medium and as a catalyst for polymerization reaction. It is also used in ceramics and some portland cement formulations. | | 製造方法 | Lithium hydroxide monohydrate
may also be made by the evaporation of a solution prepared by the reaction of
calcium hydroxide and lithium carbonate.Anhydrous lithium hydroxide may be prepared by heating the monohydrate in air or
in a vacuum. | | 一般的な説明 | Small colorless crystals. Denser than water. Contact may cause severe irritation to skin, eyes, and mucous membranes. Toxic by ingestion, inhalation and skin absorption. Used to make electric storage batteries, soaps, and lubricants.
An aqueous solution of a lithium salt below its boiling point has been considered for both a tritium breeding blanket and as a coolant in several fusion reactor designs. In order to breed sufficient tritium to fuel the reactor, a high concentration of lithium is desirable and lithium hydroxide is sufficiently soluble for this purpose. The solution would be contained in pipes and heat exchangers, most probably made from carbon steel. | | 空気と水の反応 | Soluble in water; heat of dissolution may generate steam and cause spattering. | | 反応プロフィール | LITHIUM HYDROXIDE MONOHYDRATE neutralizes acids exothermically to form salts plus water. Reacts with certain metals (such as aluminum and zinc) to form oxides or hydroxides of the metal and generate gaseous hydrogen. May initiate polymerization reactions in polymerizable organic compounds, especially epoxides. May generate flammable and/or toxic gases with ammonium salts, nitrides, halogenated organics, various metals, peroxides, and hydroperoxides. May serve as a catalyst. Reacts when heated above about 84°C with aqueous solutions of reducing sugars other than sucrose to evolve toxic levels of carbon monoxide [Bretherick, 5th Ed., 1995]. | | 健康ハザード | TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | | 火災危険 | Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. | | 純化方法 | It crystallises from hot water (3mL/g) as the monohydrate. It is dehydrated at 150o in a stream of CO2-free air. It sublimes at 220o with partial decomposition [Cohen Inorg Synth V 3 1957, Bravo Inorg Synth VII 1 1963]. |
