하이드록시 리튬 C화학적 특성, 용도, 생산

화학적 성질

White solid

용도

Lithium hydroxide is used in storage batteries and soaps and as CO2 absorber in spacecrafts.

정의

A white crystallinesolid, LiOH, soluble in water,slightly soluble in ethanol and insolublein ether. It is known as the monohydrate(monoclinic; r.d. 1.51) and inthe anhydrous form (tetragonal, r.d.1.46; m.p. 450°C; decomposes at924°C). The compound is made by reacting lime with lithium salts orlithium ores. Lithium hydroxide isbasic but has a closer resemblance togroup 2 hydroxides than to the othergroup 1 hydroxides (an example ofthe first member of a periodic grouphaving atypical properties).

일반 설명

A clear to water-white liquid which may have a pungent odor. Contact may cause severe irritation to skin, eyes, and mucous membranes. Lithium hydroxide may be toxic by ingestion, inhalation and skin absorption. Lithium hydroxide is used to make other chemicals.

공기와 물의 반응

Dilution with water may generate enough heat to cause steaming or spattering.

반응 프로필

LITHIUM HYDROXIDE SOLUTION 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].

건강위험

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.

화재위험

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.

Safety Profile

Poison by ingestion and subcutaneous routes. Mtldly toxic by inhalation. A corrosive. When heated to decomposition it emits toxic fumes of Li.

Purification Methods

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].
