How is sulfur tetrafluoride released into the atmosphere?
Sulfur tetrafluoride's production and use as a chemical agent, as an intermediate andin the treatment agent for rubbers and polymers may result in its release to the environment through various waste streams. Sulfur tetrafluoride can be formed as a degradation product of high temperature decomposition of sulfur hexafluoride. If released into the atmosphere, sulfur tetrafluoride will exist in the gas phase in the ambient atmosphere, based on a vapor pressure of 1.52X10+4 mm Hg at 25 °C. Sulfur tetrafluoride is a relatively heavy gas with a vapor density 3.78 times that of air. Therefore, if released in the atmosphere, it may tend to remain close to the ground and be transported to earth by wet deposition. Sulfur tetrafluoride reacts rapidly with water to yield hydrofluoric acid and thionyl fluoride. It also reacts and fumes in moist air. Therefore, hydrolysis is expected to be an important fate process in the ambient atmosphere. If released to soil, sulfur tetrafluoride is expected to have very high mobility based upon an estimated Koc of 27. Volatilization from moist soil surfaces would be expected to be an important fate process since the compound is a gas. However, rapid hydrolysis and leaching will attenuate the importance of volatilization from moist soil. Sulfur tetrafluoride is expected to volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation data were not available. If released into water, sulfur tetrafluoride is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Sulfur tetrafluoride hydrolyzes rapidly in water. Therefore, volatization from water and bioconcentration are not expected to be important fate processes. Occupational exposure to sulfur tetrafluoride may occur through inhalation of this compound at workplaces where sulfur tetrafluoride is produced or used. (SRC)

Overview
Sulfur tetrafluoride is the chemical compound with the formula SF4. It is a colorless corrosive gas that releases dangerous HF upon exposure to water or moisture. Despite these unwelcome characteristics, this compound is a useful reagent for the preparation of organofluorine compounds, some of which are important in the pharmaceutical and specialty chemical industries.
Structure
Sulfur in SF4 is in the formal +4 oxidation state. Of sulfur's total of six valence electrons, two form a lone pair. The structure of SF4 can therefore be anticipated using the principles of VSEPR theory: it is a see-saw shape, with S at the center. One of the three equatorial positions is occupied by a nonbonding lone pair of electrons. Consequently, the molecule has two distinct types of F ligands, two
Synthesis and manufacture
SF4 is produced by the reaction of SCl2 and NaF in acetonitrile:
3 SCl2 + 4 NaF → SF4 + S2Cl2 + 4 NaCl
SF4 is also produced in the absence of solvent at elevated temperatures.
Alternatively, SF4 at high yield is produced using sulfur (S), NaF and chlorine (Cl2) in the absence of reaction medium, also at less-desirable elevated reaction temperatures (e.g. 225–450 °C).
Use of SF4 for the synthesis of fluorocarbons
In organic synthesis, SF4 is used to convert COH and C=O groups into CF and CF2 groups, respectively. Certain alcohols readily give the corresponding fluorocarbon. Ketones and aldehydes give geminal difluorides. The presence of protons alpha to the carbonyl leads to side reactions and diminished (30–40%) yield. Also diols can give cyclic sulfite esters, (RO)2SO. Carboxylic acids convert to trifluoromethyl derivatives. For example, treatment of heptanoic acid with SF4 at 100…
Other reactions
Sulfur chloride pentafluoride (SF 5Cl), a useful source of the SF5 group, is prepared from SF4.
Hydrolysis of SF4 gives sulfur dioxide:
SF4 + 2 H2O → SO2 + 4 HF
This reaction proceeds via the intermediacy of thionyl fluoride, which usually does not interfere with the use of SF4 as a reagent.
Toxicity
SF 4 reacts inside the lungs with moisture, generating sulfur dioxide and hydrogen fluoride:
SF4 + 2 H2O → SO2 + 4 HF
