탄산, 리튬 염 C화학적 특성, 용도, 생산

화학적 성질

Lithium carbonate is a white hygroscopic powder.

물리적 성질

White monoclinic crystals; refractive index 1.428; density 2.11 g/cm3; melts at 723°C; decomposes at 1,310°C; low solubility in water (1.54 g/100g) at 0°C; 1.32 g//100g at 20°C), solubility decrease with temperature (0.72g/100g at 100°C); insoluble in acetone and ethanol.

용도

The most common lithium drug is lithium carbonate, which possesses antimania action. It is presumed that lithium alters the transport of sodium ions in neurons, thus influencing the intercellular contents of catecholamines, normalizing the mental state and not causing general lethargy. It is used for mania conditions of various origins, preventative measures, and for treating affective psychoses.

용도

Lithium carbonate is used as a compound for producing metallic lithium. Lithium carbonate is the result of treating the mineral spodumene with sulfuric acid and then adding calcium carbonate. It is used as an antidepressant.

용도

In the production of glazes on ceramic and electrical porcelain.

제조 방법

Lithium carbonate is prepared by the precipitation of lithium ion by carbonate ion from an aqueous solution. Still another process, which is carried out on a smaller scale, is the reaction of a solution of lithium hydroxide with carbon dioxide gas. Lithium carbonate precipitates and is recovered from the supernatant solution.

정의

lithium carbonate: A white solid,Li2CO3; r.d. 2.11; m.p. 723°C; decomposesabove 1310°C. It is producedcommercially by treating the ore with sulphuric acid at 250°C andleaching the product to give a solutionof lithium sulphate. The carbonateis then obtained by precipitationwith sodium carbonate solution.Lithium carbonate is used in the preventionand treatment of manicdepressivedisorders. It is also usedindustrially in ceramic glazes.

Indications

Lithium inhibits thyroidal incorporation of I- into Tg, as well as the secretion of thyroid hormones, but it does not inhibit the activity of the Na+-I- symporter or the accumulation of I- within the thyroid. Lithium offers no particular advantage over drugs of the thionamide class but may be employed for temporary control of thyrotoxicosis in patients who are allergic to both thionamides and iodide.

상표명

Eskalith (GlaxoSmithKline); Lithane (Bayer); Lithobid (JDS); Lithonate (Solvay Pharmaceuticals).

일반 설명

Lithiumcarbonate (Eskalith, Lithane) and lithium citrate(Cibalith-S) are the salts commercially available in theUnited States.

반응 프로필

A base. Decomposed by acids with the evolution of carbon dioxide. Fluorine burns fiercely on contact with Lithium carbonate.

Safety Profile

Human carcinogenic data. Poison by intraperitoneal and intravenous routes. Moderately toxic by ingestion and subcutaneous routes. Human systemic effects by ingestion: toxic psychosis, tremors, changes in fluid intake, muscle weakness, increased urine volume, nausea or vomiting, allergic dermatitis. Human reproductive effects by ingestion: effects on newborn, including Apgar score changes and other neonatal measures or effects. Human teratogenic effects by ingestion: developmental abnormalities of the cardiovascular system, central nervous system, musculoskeletal and gastrointestinal systems. An experimental teratogen. Experimental reproductive effects. Experimental carcinogen producing leukemia and thyroid tumors. Human mutation data reported. Used in the treatment of manic-depressive psychoses. Incompatible with fluorine. See also LITHIUM COMPOUNDS.

Chemical Synthesis

Lithium carbonate is synthesized by reacting lithium salts with soda or potash, followed by purification of the salt, which is not readily soluble [75].

잠재적 노출

Lithium carbonate is used in treatment of manic-depressive psychoses; to make ceramics and porcelain glaze; varnishes, dyes, pharmaceuticals, coating of arc-welding electrodes; battery alloys; nucleonics, luminescent paints; glass ceramics; lubricating greases; in aluminum production

운송 방법

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

Purification Methods

Crystallise it from water. Its solubility decreases as the temperature is raised. The solubility in H2O is 1.3% at ~10o, and 0.7% at ~100o. [D.nges in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 987 1963, Caley & Elving Inorg Synth I 1 1939.]

비 호환성

The aqueous solution is a strong base. Reacts violently with acids, powdered calcium and fluorine.Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong acids, powdered calcium, fluorine, moisture. Corrodes aluminum, copper, zinc.
