Appearance:Sulfur tetrafluoride is a colorless gas with a distinct sulfur odor. It is highly toxic by inhalation and a strong irritant to skin, eyes and mucous membranes. It 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. It is used as a fluoridizing agent and as an oil repellent.

Experimental Properties:Decomposed by concentrated sulfuric acid. Thermostable at 600 °C|Surface tension: 257 dyn/cm at -73 °C|Sulfur tetrafluoride is an extremely reactive substance instantly hydrolized by water to sulfur oxide and hydrogen fluoride.|Readily hydrolyzes. Will react with water, steam, or acids to yield toxic and corrosive fumes|For more Other Experimental Properties (Complete) data for SULFUR TETRAFLUORIDE (6 total), please visit the HSDB record page.
Air and Water Reactions:Violent reaction with water. It reacts vigorously with water and acids to yield toxic fluoride and sulfur oxide fumes, including fumes of hydrofluoric acid and sulfuric acid, and an acidic solution.
Reactive Group:Fluoride Salts, Soluble
Reactivity Alerts:Water-Reactive
Reactivity Profile:SULFUR TETRAFLUORIDE is a highly toxic and corrosive gas. On contact with water, steam, or mineral acids it decomposes and produces toxic and highly irritating fumes. When heated to decomposition it 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].
