Sulfur monochloride 98% Synonym: Sulfur chloride CAS Number Linear Formula S 2 Cl 2. Molecular Weight EC Number MDL number MFCD PubChem Substance ID NACRES NA Sulfur chloride is produced at Nouryon's LeMoyne facility, just north of Mobile, Alabama, USA. Both sulfur monochloride (S 2 Cl 2) and sulfur dichloride (SCl 2) are produced to exacting customer synthesis of sulfur chlorides is by the controlled reaction of chlorine gas with elemental sulfur.
This can be considered as an acid–base reaction, where the reagent acts as an acid, whether a protic one (e.g., hydriodic acid or iodine monochloride) or a Lewis acid (e.g., molecular iodine, which can be polarized by electrophilic solvents or catalysts), and the double-bond acts as a base (Argentini, ). Sulfur monochloride should be stored in a cool, well ventilated area, away from moisture, sources of ignition, combustibles, and oxidizers. This material is readily hydrolyzed by water, becoming highly corrosive to metals. Sulfur monochloride may be shipped via air, rail, road, and water, in stainless steel containers bearing the label.
Additional examples of sulfur ylide reactions, illustrating differences in the reactivity of dimethylsulfonium methylide and dimethyloxosulfonium methylide, are given in the following diagram. Of the two, the oxosulfonium ylide is less reactive and is thought to add reversibly to carbonyl groups, eventually forming the thermodynamically favored. Sulfur isotopes are mainly used in medical applications. S is used for the production of the therapeutic radioisotope P S is used for the production of the radioisotope P which is also used for therapeutic purposes. S can be used for the production of .

The kinetics of the isotopic exchange reactions, however, depend on both pH and by: Sulfur isotope exchange reactions in the aqueous system H 2 S-S 2 O 3 SO 4 2-were studied experimentally in the temperature range from 50 to °C and at near-neutral pH using sealed Pyrex glass tubes as reaction vessels.

exchange conditions, the S value of SOz will be %0 heavier than that of HzS (Figure ). The decrease in the equilibrium isotope effects (K - 1) with increasing temperature, as seen for the SOz-HzS exchange reaction in Tableis the basis for isotope thermometry. Exchange reactions between sulphur compounds theoretically predict.

From a Thiol-Disulfide Exchange ReactionCited by: Title Isotopic Exchange Reactions in Sulfur Monochloride Abstract approved (wtajor professor) The investigations in this thesis were aken as a part of an overall study of acid-base behavior in non-aqueous solvents.
In this research the solvent whose characteristics and behavior were investigated was sulfur rnonochloride (S2CI2). The course of ex. A specific feature of sulfur monochloride (S 2 Cl 2) is its diverse reactivity [15,16,17,18].The most useful property of this compound is its sulfurating ability.
Apart from this, S 2 Cl 2 is a strong chlorinating agent, but it is rarely used since there are many other chlorinating agents that afford higher yields of the reaction products. The oxidative ability of S 2 Cl 2 has been Cited by: The reactions described in this chapter explain that sulfur monochloride is an important reagent for the synthesis of heterocycles with various numbers of sulfur atoms and even without sulfur.
