Химические свойства
Antimony pentafluoride is a noncombustible, oily, colorless liquid with a pungent odor.Физические свойства
Colorless oily liquid; highly viscous; hygroscopic; freezes at 8.3°C; boils at 149.5°C; density 2.99 g/cm3 at 23°C; soluble in excess water (with violent reaction) and glacial acetic acid; also soluble in potassium fluoride.Использование
HF/SbF5 is an excellent medium for the preparation of alkylidene oxonium salts.1Методы производства
Antimony pentafluoride is prepared by treating antimony pentachloride with excess anhydrous hydrogen fluoride. The antimony pentafluoride is separated from the volatile byproducts by fractional distillation. It can also be prepared by allowing fluorine to react with antimony powder or molten antimony trifluoride. The main use of antimony pentafluoride is as a fluorinating agent.Подготовка
Antimony pentafluoride is prepared by the reaction of antimony pentachloride with anhydrous hydrogen fluoride:SbCl5 +5 HF → SbF5 +5 HCl
It may also be prepared from antimony trifluoride and fluorine, or by treating antimony pentaoxide with aqueous hydrofluoric acid and evaporing water.
Общее описание
A colorless, oily liquid. Fumes irritate the eyes and mucous membranes. Toxic. Corrosive to metals and tissue. Extremely dangerous to tissue; its burns may be followed by gangrene. Only shipped in cylinders. Under prolonged exposure to heat cylinders may violently rupture and rocket. Used to make other chemicals as well as a catalyst in the manufacture of other chemicals.Профиль реактивности
ANTIMONY PENTAFLUORIDE is strongly acidic. Reacts vigorously with bases. When heated to decomposition, ANTIMONY PENTAFLUORIDE emits highly toxic fumes of fluorides and metallic antimony. Reacts with ammonia to form a diammoniate.Опасность
Corrosive to skin and tissue.Угроза здоровью
The compound is irritating to eyes, skin, and lungs. Contact with eyes or skin causes severe burns. The compound is extremely toxic with a probable oral lethal dose of 5-50 mg/kg or between 7 drops and one teaspoonful for a 150 pound person (antimony salts).Пожароопасность
Reacts violently with water, to form poisonous hydrogen fluoride fumes. If confined and wet can cause explosion. May cause fire in contact with combustible material. Hazardous polymerization may not occur.Профиль безопасности
A poison by inhalation. A very reactive, corrosive liquid to skin, eyes, mucous membranes. See also FLUORIDES and ANTIMONY COMPOUNDS. Violent reaction with phosphates. When heated to decomposition it emits very toxic fumes of F and Sb.Возможный контакт
It is used as a catalyst in chemical reactions or as a source of fluorine (fluorinating reagent) in fluorination reactions.Перевозки
UN1732 Antimony pentafluoride, Hazard class: 8; Labels: 8-Corrosive material, 6.1-Poisonous materials.Методы очистки
Purify it by vacuum distillation, preferably in a quartz apparatus, and store it in quartz or aluminum bottles. It is a hygroscopic viscous liquid which reacts violently with H2O and is hydrolysed by alkalis. It is POISONOUS and attacks the skin. [Woolf & Greenwood J Chem Soc 2200 1950, Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 200 1965.]Несовместимости
Water and other forms of moisture releases hydrofluoric acid, combustible organic and siliceous materials, phosphorus, and phosphate materials. Attacks glass, ceramic, lead, and metals, including copper in the presence of moisture. 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. Antimony pentafluoride, if confined and wet may cause explosion. Antimony pentafluoride appears to have oxidizing properties; may cause fire in contact with combustible or organic materials. May react with metals, including lead, releasing flammable hydrogen gas.Утилизация отходов
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.ПЕНТАФТОРИД СУРЬМЫ запасные части и сырье
