Sulfur oxide fluorides

This was the status of the chemistry of S20, F2 at the time of the last review in 1974 (152b) however, over the last 20 years this compound has dominated sulfur oxide fluoride chemistry. The method of preparation by the low-temperature electrolysis of dilute solutions ofKS03F in fluorosulfuric acid has been improved by increasing the concentration of the dissolved salt (153), and three new preparative routes have been... 

In 1978 two new sulfur oxide fluorides were discovered, both of which contained the SF5 moiety. DesMarteau reported SF OOF and evidence for SF5OOOSF5 (187), and the existence of the unstable SF5OOOSF3 was confirmed by Czarnowski and Schumacher, who obtained it by the reaction of SF5OF with Cl2 in the gas phase at or above 180°C (188). Its thermal decomposition at temperatures between 213 and 243°C has been shown to result in the production of only SOF5 and... 

Examples of weight loss or weight gain processes are water desorption, structural water release, structural decomposition, carbonate decomposition, gas evolution, sulfur oxidation, fluoride oxidation, rehydration, and other transformations.

Perhaps the most reactive compound of the group is BiFs- It reacts extremely vigorously with H2O to form O3, OF2 and a voluminous brown precipitate which is probably a hydrated bismuth(V) oxide fluoride. At room temperature BiFs reacts vigorously with iodine or sulfur above 50° it converts paraffin oil to fluorocarbons at 150° it fluorinates UF4 to UF and at 180° it converts Brs to BrFs and BrFs, and CI2 to CIF. 

Emissions from sinter plants are generated from raw material handling, windbox exhaust, sinter discharge (associated sinter crushers and hot screens), and from the cooler and cold screen. The primary source of particulate emissions, mainly irons oxides, magnesium oxide, sulfur oxides, carbonaceous compounds, aliphatic hydrocarbons, and chlorides, are due to the windbox exhaust. Contaminants such as fluorides, ammonia, and arsenic may also be present. At the discharge end,... 

A mixture of the 2 fluorides, used at low temperature to prepare bis(pentafluoro-sulfur) oxide, is described as possibly explosive.

Phosphoryl fluoride reacts as a base and, with BF , AsF5, and SbF5, oxygen-bridged 1 1 adducts are produced (88, 89). In liquid sulfur dioxide POF3 is weakly basic and it was in such a medium that the first transition-metal complex of this oxide fluoride, [Mn(OPF j)4]2v[AsF6l2, was produced in 1979 via the intermediate Mn(S02)v 2 AsFe]2 (90). 

As stated earlier, SOF4 can be prepared by elemental fluorination of SOF2 (equation 80). Sulfur oxide tetrafluoride has been observed to behave as a fluoride ion acceptor and donor, forming Cs+[OSF5 ] and [SOF3]+[SbF6] . It also provides, with F2 gas over a CsF catalyst, an excellent route to SFjOF.i ...

Tri-n-butyldifluorophosphorane was first obtained upon interaction between tri-re-butylphosphine and hexafluoro-thioacetone dimer.The method described here involves the reaction of tri-n-butylphosphine sulfide with antimony-(III) fluoride. The method is more generally apphcable in the synthesis of difluorophosphoranes from tertiary phosphine sulfides. The only previously reported difluoro-phosphorane, triphenyldifluorophosphorane, was obtained by the reaction of triphenylphosphine or triphenylphos-phine oxide with sulfur(IV) fluoride under autogenous pressure. ... 

The incineration of liquid and solid wastes produces gases with a variety of potential corrosives present. Usually they are some combination of nitrogen, phosphorus and sulfur oxides and some hydrogen fluoride, but the primary contaminant is almost always hydrogen chloride. The exact composition oftentimes is variable and unpredictable in any one incinerator. Before incineration gases can be vented, they must be scrubbed of these noxious pollutants.
