Sulphur dichloride

Liquid sulphur dioxide is a solvent for a number of substances, for example iodine, sulphur, some sulphites, potassium iodide and sulphur dichloride oxide, SOClj (see below). The liquid can be assumed to ionise slightly, thus ... 

Hence, for example, sulphur dichloride oxide behaves as an acid and a sulphite as a base thus ... 

Sulphur dioxide is oxidised by chlorine in the presence of charcoal or camphor to give sulphur dichloride dioxide sulphuryl chloride), SOjCl ... 

Sulphur and tellurium form a chloride of formula XClj. Sulphur dichloride SClj is a red liquid at room temperature whilst the corresponding tellurium compound is a black solid. 

SULPHUR DICHLORIDE OXIDE, THIONYL CHLORIDE, SOClj... 

Sulphur dichloride oxide (thionyl chloride) on the hydrated chloride can also be used to produce the anhydrous chloride in certain cases, for example copper(II) chloride and chromium(III) chloride ... 

By the reaction of sulphur dichloride oxide with the hydrated chloride ... 

Nickel forms yellow anhydrous halides NiXjlX = F. Cl. Br) and a black iodide Nil2 all these halides are made by direct combination of the elements, and the chloride by reaction of sulphur dichloride oxide with the hydrated salt. All dissolve in water to give green solutions from which the hydrates can be crystallised the solutions contain the ion [NifHjOls], and the chloride crystallises as NiCl2.6H2O, nickel(II) chloride hexahydrate. 

Propylene oxide Sodium chlorate Sulphur dichloride... 

With sulphur dichloride the hydrolysis is particularly exothermic. 

In contact with aluminium, disulphur dichloride provokes the instantaneous ignition of the metal. Lithium batteries contain thionyl chloride. A large number of explosions of batteries have been explained by the violent interaction of lithium with the chloride, which was assumed to be reieased through the anode. Sodium combusts in contact with thionyl chloride vapour heated to a temperature of 300°C. Finally, sulphur dichloride gives rise to explosive mixtures on impact with sodium. 

Acetone is used. However, if sulphur dichloride in excess is present in too large quantities, the reaction becomes particularly dangerous. 

Yet other processes have used sulphuryl chloride (S02C12), thionyl chloride (SOCl2) or sulphur dichloride (SC12) as chlorinating agents. 

Preparation of Sulphur Dichloride. (Perform the experiment in a fume cupboard ). Put a test tube with sulphur chloride obtained in the preceding experiment into a beaker with ice and pass a strong stream of dry chlorine through the liquid. How does the colour of the liquid change ... 

Sulphur dichloride separated as a finely divided buff-yellow powder from mixtures c ntabling 59-2 to G4-9 atoms of chlorine per cent. (i.e. 61 G to 67-2 per cent, chlorine). A portion was recrystalliscd from light petroleum at low temperatures and its composition confirmed by analysis.
