Fluorine-sulfur compounds with antimony

LIQUID AMMONIA (7664-41-7, anhydrous, compressed gas or cryogenic liquid 1336-21-6, solution in water) Difficult to ignite, but can detonate in confined spaces in fire. Reacts violently with strong oxidizers, acids (nitric, hydrochloric, sulfuric, picric, hydro-bromic, hydrochlorous, etc.). Shock-, temperature-, and pressure-sensitive compounds are formed with antimony, chlorine, germanium compounds, halogens, heavy metals, hydrocarbons, mercury oxide, silver compounds (azides, chlorides, nitrates, oxides). Fire and/or explosions may be caused by contact with acetaldehyde, acrolein, aldehydes, alkylene oxides, amides, antimony, boron, boron halides, boron triiodide, bromine, bromine chloride, chloric acid, chlorine, chlorine monoxide, o-chloronitrobenzene, l-chloro-2,4-dinitrobenzene, chlorosilane, chloromelamine, chromium trioxide, chromylchloride, epichlorohydrin, fluorine, hexachloromelamine, hypochlorites (do not mix ammonia with liquid household... 

In the first section of this chapter some of the properties of the elements hydrogen, carbon, nitrogen, phosphorus, arsenic, antimony, bismuth, oxygen, sulfur, selenium, tellurium, fluorine, chlorine, bromine, and iodine are described. The following sections are devoted to some of their compounds with one another, especially the single-bonded normal-valence compounds. Compounds of nonmetals with oxygen are discussed in the following chapter. 

The magnetic criterion is particularly valuable because it provides a basis for differentiating sharply between essentially ionic and essentially electron-pair bonds Experimental data have as yet been obtained for only a few of the interesting compounds, but these indicate that oxides and fluorides of most metals are ionic. Electron-pair bonds are formed by most of the transition elements with sulfur, selenium, tellurium, phosphorus, arsenic and antimony, as in the sulfide minerals (pyrite, molybdenite, skutterudite, etc.). The halogens other than fluorine form electron-pair bonds with metals of the palladium and platinum groups and sometimes, but not always, with iron-group metals. 

Halogen atoms, usually chlorine or bromine (rarely iodine or fluorine ) are generally introduced by the action of the elementary halogen on the compound to be substituted. It is often necessary to use a catalyst otherwise chlorine adds instead of substitutes (replacing hydrogen). The catalyst most commonly employed is iron (ferric chloride), sometimes iron with a trace of iodine and, less frequently, antimony, sulfur, or phosphorous compounds.
