Toxicity | An element used clinically as one of its salts. It is effective against both mania and depression. Despite its effectiveness, there are no clear mechanisms that have been directly related to its therapeutic effectiveness although its inhibition of the formation of inositol from inositol phosphate is thought to be important. At therapeutic concentrations, lithium causes almost no discernible psychotropic effects in healthy humans. The major complaints when the serum concentrations of the drug are carefully monitored include slight muscular weakness, thirst, and excessive urination. The major difficulty with lithium is that a fairly high concentration of the ion is needed in the blood (0.5_x0002_1.0 mmol/L) for maintenance, higher for acute mania. Toxic symptoms (which can involve many physiological symptoms) may occur, however, at doses of 1.5 mmol/L or higher. This low therapeutic index is indicative of the need for regular monitoring of lithium concentrations in the serum. |
Raw Materials | Lithium chloride |
silvery white soft metal. Melting point 180. 54 deg C; Boiling point of 1347 deg C, there are data for (1336±5) deg C; d20 0.534. Mohs hardness 0.6. It is hardly oxidized in dry air at room temperature. The lowest reactivity in the alkali metal, but can react with nitrogen. Chemical reactivity is very high, and halogen, sulfur, phosphorus and other intense chemical reaction, causing combustion. In the humid air or water, acid reaction release hydrogen and heat, can cause combustion.
lithium metal is used as a raw material and is distilled at a low temperature for a long time to precipitate lithium containing a large amount of impurities. The apparatus is cooled and filled with refined argon gas, and then subjected to distillation at a higher temperature to collect purified lithium metal, and then subjected to repeated distillation to obtain highly pure lithium.
It is used for making each battery, non-ferrous alloy, and the like.
has a strong corrosive, eye and skin contact cause irritation or burns. Staff should be protected. Store in a cool, ventilated warehouse. Protection from direct sunlight. Operation in argon treatment. Shall be stored in aliquots of oxidant, fluorine and chlorine. Production personnel should be protected and the workshop should be well ventilated.
