Sulfuryl chloride is used as a source of Cl 2.Because it is a pourable liquid, it is considered more convenient than Cl 2 to dispense.. Sulfuryl chloride is used in the conversion of C−H to C−Cl adjacent to activating substituents such as carbonyls and sulfoxides: [5] [6]
Sulfur concrete has a low porosity and is a poorly permeable material. Its low hydraulic conductivity slows down water ingress in its low porosity matrix and so decreases the transport of harmful chemical species, such as chloride (pitting corrosion), towards the steel reinforcements (physical protection of steel as long as no microcracks develop in the sulfur concrete matrix).
Treatment of sulfur with hydrogen gives hydrogen sulfide.When dissolved in water, hydrogen sulfide is mildly acidic: [5] H 2 S ⇌ HS − + H +. Hydrogen sulfide gas and the hydrosulfide anion are extremely toxic to mammals, due to their inhibition of the oxygen-carrying capacity of hemoglobin and certain cytochromes in a manner analogous to cyanide and azide.

SCl 2 is used in organic synthesis.It adds to alkenes to give chloride-substituted thioethers. Illustrative is its addition to 1,5-cyclooctadiene to give a bicyclic thioether [2] A well tested method for the production of the mustard gas bis(2-chloroethyl)sulfide, is the addition of ethylene to sulfur dichloride: [3]
It is an intermediate, chemically and conceptually, between sulfuryl chloride (SO 2 Cl 2) and sulfuric acid (H 2 SO 4). [6] The compound is rarely obtained pure. Upon standing with excess sulfur trioxide, it decomposes to pyrosulfuryl chlorides: [7] 2 ClSO 3 H + SO 3 → H 2 SO 4 + S 2 O 5 Cl 2
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
In the presence of aluminium chloride (AlCl 3), S 2 Cl 2 reacts with benzene to give diphenyl sulfide: 8 S 2 Cl 2 + 16 C 6 H 6 → 8 (C 6 H 5 ) 2 S + 16 HCl + S 8 Anilines (1) react with S 2 Cl 2 in the presence of NaOH to give 1,2,3-benzodithiazolium chloride (2) ( Herz reaction ) which can be transformed into ortho -aminothiophenolates (3 ...
