Anwendungen & Verwendung

Beschreibung

Fluorine is a highly toxic, pale yellow gas about 1.3 times as heavy as air at atmospheric temperature and pressure. When cooled below its boiling point (-306.8°F or -188.2°C), it is a liquid about 1.5 times as dense as water.

Occurrence

Fluorine is the 13th most abundant element on the Earth. It makes up about 0.06% of theEarth’s crust. Fluorine is widely distributed in many types of rocks and minerals, but neverfound in its pure form. Fluorine is as plentiful as nitrogen, chlorine, and copper, but lessplentiful than aluminum or iron.The most abundant fluorine mineral is fluorite—calcium fluoride (CaF2)—which is oftenfound with other minerals, such as quartz, barite, calcite, sphalerite, and galena. It is mined in Cumberland, England, and in Illinois in the United States. Other minerals from which fluorineis recovered are fluorapatite, cryolite, and fluorspar, which are found in many countriesbut mainly in Mexico and Africa.Today fluorine is produced by the electrolysis of potassium fluoride (KF), hydrofluoric acid(HF), and molten potassium acid fluoride (KHF2).

Verwenden

Fluorine is used in the manufacture of vari ous fluorocarbons and fluorides, as a rocketpropellant, and in many inorganic and or ganic syntheses.

Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Risk of fire and explosion on contact with many substances. See Chemical Dangers.
BrandpotenzialNot flammable
GesundheitsgefahrenPoisonousmay be fatal if inhaled. Vapor extremely irritating. Contact may cause burns to skin and eyes. Chronic absorption may cause osteosclerosis and calcification of ligaments. (EPA, 1998)· TOXIC and/or CORROSIVEmay be fatal if inhaled or absorbed through skin.
GefahrenübersichtFluorides, hydrogen fluoride, and fluorine are chemically related. Fluorine is a naturally-occurring, pale yellow-green gas with a sharp odor. It combines with metals to make fluorides such as sodium fluoride and calcium fluoride, both white solids. Sodium fluoride dissolves easily in water, but calcium fluoride does not. Fluorine also combines with hydrogen to make hydrogen fluoride, a colorless gas. Hydrogen fluoride dissolves in water to form hydrofluoric acid. Fluorine and hydrogen fluoride are used to make certain chemical compounds. Hydrofluoric acid is used for etching glass. Other fluoride compounds are used in making steel, chemicals, ceramics, lubricants, dyes, plastics, and pesticides. Fluorides are often added to drinking water supplies and to a variety of dental products, including toothpaste and mouth rinses, to prevent dental cavities. UPDATE: In 2015, thePHS replacedthe 1962 Drinking Water Standards from 0.7""1.2 mg/L to an optimal fluoride concentration of 0.7 mg/L. This is to provide optimal concentration of fluoride in drinking water that provides the best balance of protection from dental caries while limiting the risk of dental fluorosis.Fluorine gas is a severe irritant to the eyes, skin, and respiratory tract. Liver injury has been reported in experimental animals exposed to high concentrations. The TLV Basis is fluorosis and eye irritationA TLV-TWA of 0.1 ppm is expected to minimize the potential for skeletal fluorosis. This is based on the assumption that drinking water and inhalation doses produce equivalent fluorosis. Fluorine gas produces hydrofluoric acid upon contact with water. [ACGIH] Liquid causes second and third degree burns after short skin exposure[CHRIS] Highly corrosive to skin[Quick CPC] A lachrymator[CHEMINFO] May cause respiratory tract irritation and pulmonary edemaEvaporating liquid can cause frostbite[ICSC] See FLUORIDES.

BrandbekämpfungA few whiffs of the gas or vapor could cause death. Gas, vapor or liquid could be fatal on penetrating the firefighters' normal full protective clothing. Only special protective clothing designed to protect against fluorine should be usedthe normal full protective clothing available to the average fire department will not provide adequate protection. Do not direct water onto fluorine leaks as the fire may be intensified.NO water. In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position.
Erste-Hilfe-MaßnahmenFresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.

Gesundheitliche AuswirkungenExposure to high levels of fluoride can result in denser bones. However, if exposure is high enough, these bones may be more fragile and brittle and there may be a greater risk of fracture. Chronic exposure may also cause dental fluorosis, which alters the appearance of children's teeth during tooth development. (L963, L969)

UmweltverhaltenTERRESTRIAL FATE: Elemental fluorine was found to be very mobile in both sandy and sandy loam soils(1). Fluorine decomposes in water to form hydrofluoric acid (HF), hydrogen peroxide (H2O2) and oxygen fluoride (OF2)(2)therefore, fluorine is expected to decompose in moist soils as it reacts with water(SRC). Fluorine is a gas at environmental temperatures(2) which indicates volatilization from dry soil will occur(SRC).AQUATIC FATE: Fluorine decomposes in water to form hydrofluoric acid (HF), hydrogen peroxide (H2O2) and oxygen fluoride (OF2)(1). This hydrolysis will be the dominant fate process in water(SRC). Volatilization, bioconcentration and adsorption to sediment will not be important fate processes(SRC).ATMOSPHERIC FATE: At atmospheric pressures, fluorine is a gas above its boiling point of -188.13 °C(1), and therefore, will exist as a gas in the ambient environment(SRC). Fluorine gas is a powerful oxidizing agent that reacts with water to form HF and other compounds(1,2). It also reacts readily with many gases and oxidant species(1,2) which indicates that fluorine gas will be converted to a variety of fluorine compounds in the atmosphere(SRC). The elemental form of fluorine, a pale yellow-green, irritating gas with a sharp odor, is so chemically reactive that it rarely occurs in the environment in the elemental state(3).

ToxizitätsübersichtFluoride ions are incorporated into bone by substituting for hydroxyl groups in the carbonate-apatite structure to produce hydroxyfluorapatite, thus altering the mineral structure of the bone. Alteration in mineralization increases hardness and bone mass, but also decreases mechanical strength. A portion of the circulating inorganic fluoride acts as an enzyme inhibitor because it forms metalfluoride-phosphate complexes that interfere with the activity of those enzymes requiring a metal ion cofactor. In addition, fluoride may interact directly with the enzyme or the substrate. It is a general inhibitor of the energy production system of the cell. Fluorine may bind calcium and decrease its concentration. This is thought to indirectly inhibit amelogeninase activity, resulting in altered crystal growth and subsequently causing dental fluorosis. (L963)

Symptoms of fluoride exposure include abdominal pain, diarrhea, dysphagia, hypersalivation, mucosal injury, nausea, vomiting. Electrolyte abnormalities including hyperkalemia, hypocalcemia, hypoglycemia, and hypomagnesemia may occur. Neurological symptoms include headache, muscle weakness, hyperactive reflexes, muscular spasms, paresthesia seizures, tetanic contractions, and tremors. In severe cases, multiorgan failure will occur. Death typically results from cardiac arrest, shock, widening of QRS, and various arrhythmias occur. (L963, L969)

RCRA-AnforderungenP056As stipulated in 40 CFR 261.33, when fluorine, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to federal and/or state hazardous waste regulations. Also defined as a hazardous waste is any container or inner liner used to hold this waste or any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5(e)).D002A solid waste containing fluorine may become characterized as a hazardous waste when subjected to testing for corrosivity as stipulated in 40 CFR 261.22, and if so characterized, must be managed as a hazardous waste.
