Lithium hydroxide (LiOH) is an inorganic compound that is produced commercially through electrolysis of dilute lithium chloride solution. It is a white crystalline solid that is highly soluble in water and alcohol. The lithium hydroxide molecule has an ionic structure consisting of lithium cations (Li+) and hydroxide anions (OH-). Each lithium ion is surrounded by four hydroxide ions in a tetrahedral arrangement. Lithium hydroxide has high thermal stability and does not decompose below 500°C. It has a melting point of 523°C and a boiling point of 1325°C. In water, it dissociates into lithium and hydroxide ions according to the following reaction: LiOH (s) → Li+ (aq) + OH- (aq) The hydroxide ions impart basic properties to lithium hydroxide. Aqueous solutions of LiOH are strongly alkaline with a pH of around 13. Its basic character arises due to the powerful nucleophilicity of OH- ions. Industrial Production and Uses Nearly 80% of the lithium hydroxide made globally is consumed in the manufacturing of lubricating greases. It acts as a thickening agent in the synthesis of lithium hydroxide monohydrate grease. Other uses of lithium hydroxide include: - Manufacture of butyllithium and other lithium organic compounds. The reaction of n-butyllithium with lithium hydroxide produces butyllithium which is used as a strong base in organic synthesis. - Production of lithium compounds. Heating lithium hydroxide with lithium carbonate yields lithium oxide which in turn forms other lithium salts. - Flux in aluminum production. It lowers the melting point of aluminum oxide allowing more efficient aluminum smelting. - Manufacture of glass-ceramics. Lithium hydroxide strengthens glass and reduces thermal expansion when added in small quantities to glass batches. - Storage batteries. It is used as an electrolyte in some lithium-ion batteries where it conducts lithium ions between the anode and cathode. - Soap and detergent manufacture. Traces of lithium ions impart gloss and silkiness to washed fabrics and dishes. Environmental and Health Impacts Being a strong base, lithium hydroxide poses hazards if mishandled. Direct contact with skin or eyes can cause irritation, burns and blindness on prolonged exposure. Inhalation of dust particles may lead to sore throat, coughing and breathing difficulties. The recommended exposure limits for lithium hydroxide are generally 1 mg/m3 as an 8-hour time-weighted average concentration. Synthesis and Purification Methods The industrial process employed commercially for producing lithium hydroxide involves electrolysis of a saturated lithium chloride solution between carbon anodes and aluminium cathodes. In the electrolysis cell, lithium ions migrate to the cathode where they react with water according to the equation: Li+ + H2O + e- → LiOH + 1/2H2 The resulting lithium hydroxide dissolves in the solution which is then concentrated and crystallized. Aluminium impurities from the cathode also get codeposited which are removed by a purification step. An alternate laboratory method uses reaction of slaked lime (calcium hydroxide) with lithium carbonate: Ca(OH)2 + Li2CO3 → 2LiOH + CaCO3 The lithium hydroxide produced is filtered, washed and dried. Commercially, this route is less economical than the electrolysis process due to higher costs. Nuclear Applications Pure lithium hydroxide finds some niche uses in nuclear technology owing to lithium's properties as a neutron moderator. Finely divided lithium hydroxide powders are applied as a protective neutron-absorbing coating on core structures of some research reactors. This coating controls excess reactivity and provides an emergency shutdown mechanism if temperatures rise abnormally. Lithium also has one of the highest thermal neutron absorption cross-sections. So lithium-containing compounds like lithium hydroxide can be used as control and safety rods in nuclear reactors to regulate the fission process. Some future reactor designs may employ molten lithium or lithium salt mixtures as reactor coolants as well as breeder materials. The unique nuclear characteristics of lithium make it an important material in emerging nuclear technologies. lithium hydroxide is a commercially significant industrial chemical produced mainly through electrolysis. It has diverse applications leveraging its high solubility, basic properties and ability to conduct lithium ions. Whiletoxic if mishandled, proper handling reduces risks. Future prospects lie in expanding lithium ion battery and specially nuclear uses owing to lithium's neutron moderating and absorbing ability useful fornext generation nuclear technologies. Overall, the versatile properties and growing lithium demands ensure lithium hydroxide's importance will keep rising across multiple industries.
