説明

Sodium fluoride, NaF, is a binary salt that is a clear, lustrous crystal or white powder. The insecticide grade is frequently dyed blue. It is soluble in water and has a specific gravity of 2.558, which is heavier than water. Sodium fluoride is highly toxic by ingestion and inhalation, and is also strongly irritating to tissue. The TLV is 2.5 mg/m3 of air. The four-digit UN identification number is 1690. The primary uses are fluoridation of municipal water at 1 ppm, as an insecticide, rodenticide, and fungicide, and in toothpastes and disinfectants.

化学的特性

Sodium fluoride is a white powder or colorless crystals. Often used in a solution. Odorless. Pesticide grade is often dyed blue.

使用

Sodium fluoride (NaF), in the concentration of one ppm, is added to municipal drinking water to help reduce tooth decay. It is also used as an insecticide, fungicide, and rodenticide, as well as in the manufacture of adhesives, disinfectants, and dental products.

As insecticide, particularly for roaches and ants; in other pesticide formulations; constituent of vitreous enamel and glass mixes; as a steel degassing agent; in electroplating; in fluxes; in heat-treating salt compositions; in the fluoridation of drinking water; for disinfecting fermentation apparatus in breweries and distilleries; preserving wood, pastes and mucilage; manufacture of coated paper; frosting glass; in removal of HF from exhaust gases to reduce air pollution. Dental caries prophylactic.

定義

ChEBI: A metal fluoride salt with a Na(+) counterion.

製造方法

Sodium fluoride is prepared by adding sodium hydroxide or sodium carbonate to a 40% solution of hydrofluoric acid. In excess hydrofluoric acid, sodium bifluoride, NaHF2 , is formed. NaF also is made by fusion of cryolite with caustic soda. Technical grade products are usually sold at 90 to 95% purity.

brand name

一般的な説明

Sodium fluoride is a colorless crystalline solid or white powder, or the solid dissolved in a liquid. Sodium fluoride is formed by the reaction of sodium carbonate and hydrofluoric acid. Sodium fluoride is soluble in water. Sodium fluoride is noncombustible. Sodium fluoride is corrosive to aluminum. Sodium fluoride is used as an insecticide. Sodium fluoride is also used to fluorinate water supplies, as a wood preservative, in cleaning compounds, manufacture of glass, and for many other uses.

危険性

Toxic by ingestion and inhalation, strong irritant to tissue.

健康ハザード

Ingestion may cause vomiting, abdominal pain, diarrhea, convulsions, collapse, thirst, disturbed color vision, acute toxic nephritis.

健康ハザード

The acute toxicity of fluorides is generally moderate. High exposures may cause irritation of the eyes and respiratory tract. Ingestion of fluoride may cause a salty or soapy taste, vomiting, abdominal pain, diarrhea, shortness of breath, difficulty in speaking, thirst, weak pulse, disturbed color vision, muscular weakness, convulsions, loss of consciousness, and death. In humans the approximate lethal dose of NaF by ingestion is 5 g. Repeated inhalation of fluoride dust may cause excessive calcification of the bone and calcification of ligaments of the ribs, pelvis, and spinal column. Repeated skin contact may cause a rash Fluorides have not been shown to be carcinogenic or to show reproductive or developmental toxicity in humans.

火災危険

Fluorides are not combustible.

火災危険

Fluorides are not combustible.

火災危険

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

燃焼性と爆発性

Fluorides are not combustible.

工業用途

Sodium fluoride is a white to yellowish powder, poorly soluble in water. The NaF solubility in water is 3.85% at 15 °C and 4.21% at 25 °C. Commercially, NaF is obtained by reacting hydrofluoric acid with sodium hydroxide. This reaction is a by-product during the production of superphosphates from fluoro-apatite. Sodium fluoride is an important depressant used exclusively during beneficiation of non-sulfide minerals, as well as the rare-earth minerals as a depressant alone or in combination with other depressants. It is used together with starch as co-depressant for rutile and ilmenite during zirconium– titanium separation or during reverse silicate flotation from rutile and ilmenite with cationic collectors. Although it is believed that Na2F is a silicate depressant, studies have shown that it does not depress silicate minerals. In fact, it improves depression of oxides and silicates when used with other depressants.

臨床応用

Sodium fluoride (NaF) promotes the proliferation and activity of osteoblasts and is classified as a nonhormonal bone-forming agent. Because treatment with NaF induces bone formation, it is essential that this therapy be coupled with oral calcium supplementation (1,000 mg/day). Additionally, NaF exhibits moderate antiresorptive activity, because it inhibits osteoclastic activity when it is absorbed into the bone matrix. In the treatment of osteoporosis, the therapeutic window for this agent is fairly narrow: Doses less than 45 mg/day are subtherapeutic, and doses in excess of 75 mg/day impair bone mineralization. In addition, the bone that is formed in the presence of NaF is neither as well mineralized nor as strong as normal bone tissue. In fact, some

安全性プロファイル

Human poison by ingestion. Experimental poison by ingestion, skin contact, intravenous, intraperitoneal, subcutaneous, and intramuscular routes. Human systemic effects: changes in teeth and supporting structures, cyanosis, diarrhea, EKG changes, fluid intake, headache, hypermotihty, increased immune response, muscle weakness, musculo-skeletal changes, nausea or vomiting, paresthesia, ptosis (drooping of the eyelid from sympathetic innervation), respiratory depression, salivary gland changes, tremors. Experimental teratogenic and reproductive effects. Human mutation data reported. A corrosive irritant to skin, eyes, and mucous membranes. Questionable carcinogen with experimental tumorigenic data. It is very phytotoxic. When heated to decomposition it emits toxic fumes of Fand NazO. Used in chemical cleaning, for fluoridation of drinking water, as a funglcide and insecticide.

職業ばく露

Widely used in the chemical industry; in water treatment and fluoridation of drinking water; as an insecticide, fungicide, and rodenticide; chemical cleaning; electroplating, glass manufacture; vitreous enamels; preservative for adhesives; toothpastes, disinfectant, dental prophylaxis; also used orally in the treatment of various bone diseases to increase bone density and to relieve bone pain.

輸送方法

UN1690 Sodium fluoride, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

純化方法

Crystallise NaF from water by partial evaporation in a vacuum desiccator, or dissolve it in water, and precipitate ca half of it by adding EtOH. The precipitate is dried in an air oven at 130o for one day, and then stored in a desiccator over KOH. Its solubility in H2O is 4% at 15o and 4.3% at 25o. [Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 235 1963].

不和合性

Contact with acids release toxic gas. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.

廃棄物の処理

In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
