화학적 성질
lithium hydroxide (LiOH) is a white solid made industrially as the monohydrate (LiOH.H2O) by reacting lime with a lithium ore or with a salt made from the ore. Lithium hydroxide has a closer resemblance to the group 2 hydroxides than to the group 1 hydroxides.

Reactivity AlertsKnown Catalytic Activity
Reactivity Profile
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].
Chemical Dangers
Decomposes on heating above 924 °C . This produces toxic fumes. The solution in water is a strong base. It reacts violently with acid and is corrosive to aluminium, tin and zinc. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Reacts with strong oxidants.

추가 설명
정의A white crystalline solid, LiOH, is soluble in water, slightly soluble in ethanol, and insoluble in ether. It is known as the monohydrate (monoclinic; r.d. 1.51) and in the anhydrous form (tetragonal, r.d. 1.46; m.p. 450°C; decomposes at 924°C). The compound is made by reacting lime with lithium salts or lithium ores. Lithium hydroxide is basic but has a closer resemblance to group 2 hydroxides than to the other group 1 hydroxides (an example of the first member of a periodic group having atypical properties).
