Product Description Product DescriptionBasic Information The chemical formula is LiBr, and the English name is Lithium Bromide. Its molecular weight is 86.845.Physical and Chemical Properties Appearance: Usually presented as white crystalline powder or granules. It is highly hygroscopic and will gradually dissolve by absorbing moisture from the air when placed for a long time.Solubility: It is extremely soluble in water and can also dissolve in organic solvents such as ethanol and ether. Its aqueous solution is neutral or slightly alkaline.Melting and Boiling Points: The melting point is 550 °C, and the boiling point is 1265 °C.Density: 3.464 g/cm3.Main Applications Refrigeration Field: It is a key working medium in lithium bromide absorption refrigerators. By taking advantage of its property of absorbing and releasing water vapor at different temperatures, it realizes the refrigeration cycle. This type of refrigeration has the advantages of quiet operation, no vibration, and no damage to the ozone layer.Pharmaceutical Industry: In medicine, it is used as a hypnotic and sedative. It can regulate the central nervous system, playing roles such as calming and hypnotizing.Other Aspects: It can also be used as a catalyst in organic synthesis, accelerating the progress of certain chemical reactions. Additionally, it serves as a raw material for the preparation of other lithium compounds, being used to produce some special lithium salt products.Production Methods The main production methods include the lithium hydroxide method and the lithium carbonate method. In the lithium hydroxide method, lithium hydroxide reacts with hydrobromic acid. After processes such as evaporation and crystallization, the lithium bromide product is obtained. In the lithium carbonate method, lithium carbonate reacts with hydrobromic acid, and then through operations such as impurity removal, concentration, and crystallization, lithium bromide is prepared.Precautions Lithium bromide is irritating to a certain extent and can irritate the eyes, skin, and respiratory tract. During use and storage, direct contact with the skin and eyes should be avoided. Keep the packaging sealed and store it in a dry and well - ventilated place.
