sulfur tetrafluoride usage and synthesis

selective organic fluorinating agent	sulfur tetrafluoride is a selective organic fluorinating agent, s atoms form σ bond with sp3d hybrid orbitals on its molecular structure, molecular shape is distorted tetrahedral, at normal temperature and pressure, it is colorless gas with strong stimulus foul odor of gas which similar to sulfur dioxide, it is toxic, it does not burn and explode in the air, at 600 ℃ it remains stable. it strong hydrolyzes and emits white smoke in the air. when encounteres water environment, it will cause corrosion of similar to hydrofluoric acid. it fully hydrolyzes into hydrofluoric acid and sulfur dioxide, the partial hydrolysis can produce toxic thionyl fluoride, alkali solution can fully absorb into it and turn it into non-toxic salts; it is soluble in benzene. sulfur tetrafluoride (abbreviation of sf4) is currently widely used and it is the most potent selective organic fluorinating agent, it can selectively fluorinate carbonyl and hydroxyl (substituted oxygen of carbonyl compounds); it is widely used in chemical high-grade and high-end liquid crystal material medicine, pesticide intermediates production industry, it has irreplaceable position. the above information is edited by the chemicalbook of wang xiaodong.
category	harmful gases.
toxicity	mid toxicity.
acute toxicity	inhalation - rat lcl0: 19 ppm / 4h.
flammability hazard characteristics	it can decompose into toxic hydrogen fluoride and sulfur dioxide gas when meets water.
storage characteristics	treasury ventilation low-temperature drying; it should be stored separately with acids, flammable, explosive materials.
extinguishing agent	water
professional standards	twa 2.5 mg (fluorine) / cubic meter
general description	sulfur tetrafluoride is a colorless gas with a distinct sulfur odor. sulfur tetrafluoride is highly toxic by inhalation and a strong irritant to skin, eyes and mucous membranes. sulfur tetrafluoride reacts vigorously with water and acids to yield toxic fluoride and sulfur oxide fumes and an acidic solution. sulfur tetrafluoride is heavier than air. under prolonged exposure to fire or intense heat the containers may violently rupture or rocket. sulfur tetrafluoride is used as a fluoridizing agent and as an oil repellent.
air & water reactions	violent reaction with water. sulfur tetrafluoride reacts vigorously with water and acids to yield toxic fluoride and sulfur oxide fumes and an acidic solution.
reactivity profile	sulfur tetrafluoride is a highly toxic and corrosive gas. on contact with water, steam, or mineral acids sulfur tetrafluoride decomposes and produces toxic and highly irritating fumes. when heated to decomposition sulfur tetrafluoride emits very toxic fluoride and sulfur oxides fumes [lewis, 3rd ed., 1993, p. 1197]. explosively violent reactions with 2-(hydroxymethyl)furan or 2-methyl-3-butyn-2-ol even below -50° c have been recorded [bretherick, 5th ed., 1995, p. 1432]. ignition or explosion may occur on contact with dioxygen difluoride even below -100° c [streng, a. g., chem. rev., 1963, 63, p. 615].
health hazard	sulfur tetrafluoride is highly toxic by inhalation; it is a strong irritant to eyes and mucous membranes. poisonous; may be fatal if inhaled. contact may cause burns to skin and eyes. contact with liquid may cause frostbite.
fire hazard	container may explode in heat of fire. when heated to decomposition, sulfur tetrafluoride emits very toxic fumes of fluorides and sulfur oxides. reacts violently with water. sulfur tetrafluoride is decomposed by concentrated sulfuric acid. thermostable to 1112f.
