Lithium bromide Chemical Properties,Usage,Production

  • Description Lithium bromide (LiBr) is the chemical compound of lithium and bromine. It has extreme hygroscopic, making it a suitable desiccant in the air conditioning systems. It can also be used in absorption chilling together with water. It is also useful in the organic synthesis such as forming adduct with some pharmaceuticals. In medical fields, it can be used as a sedative and used for the treatment of bipolar disorder. It can be manufactured by the treatment of lithium carbonate with hydrobromic acid. 
  • Physical properties White cubic crystals; hygroscopic; refractive index 1.784; density 3.464 g/cm3; melts at 550°C; vaporizes at 1,265°C; highly soluble in water (145g/100g at 4°C), much greater solubility in hot water (254g/100g at 90°C); soluble in methanol, ethanol and ether; slightly soluble in pyridine; vapor pressure of aqueous solutions at 52 and 68% concentrations at 25°C are 5 and 0.7 torr, respectively.
  • Uses Lithium bromide is used in absorption, refrigeration and air-conditioning systems. A highly concentrated solution of the salt is an efficient absorbent of water vapor. The vapor pressure of such solution is very low. Other applications include the use of the salt as a swelling agent for wool, hair and other organic fibers; as a catalyst in dehydrohalogenation reactions; and as a sedative and hypnotic in medicine.
  • Preparation Lithium bromide is prepared by neutralizing lithium hydroxide or lithium carbonate with an aqueous solution of hydrobromic acid, followed by concentration and crystallization: LiOH + HBr → LiBr + H2O Li2CO3 + HBr → LiBr + CO2 + H2O The salt is usually obtained as hydrates. Anhydrous lithium bromide is obtained by heating hydrated salt under vacuum.
  • Chemical Properties White powder
  • Uses As humectant, in air-conditioning systems.
  • Definition ChEBI: A lithium salt in which the counterion is bromide. The anhydrous salt forms cubic crystals similar to common salt.
  • Purification Methods Crystallise it several times from water or EtOH, then dry it under high vacuum for 2 days at room temperature, followed by drying at 100o. Its solubility in H2O is 167% at ~20o, and 250% at ~100o. It is deliquescent and should be stored in a tightly stoppered vessel.
