  2. Sulfuryl chloride - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl_chloride

    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]

  3. Mass fraction (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_fraction_(chemistry)

    Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt.% or % w/w; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size ; mole fraction (percentage by moles , mol%) and volume fraction ...

  4. Chlorosulfonyl isocyanate - Wikipedia

    en.wikipedia.org/wiki/Chlorosulfonyl_isocyanate

    CSI is prepared by treating cyanogen chloride with sulfur trioxide, the product being distilled directly from the reaction mixture. [1] SO 3 + ClCN → ClSO 2 NCO. In this transformation, both the carbon and the nitrogen termini of CN are functionalized. The structure of CSI is represented as ClS(O) 2-N=C=O.

  5. Sulfur dichloride - Wikipedia

    en.wikipedia.org/wiki/Sulfur_dichloride

    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] SCl 2 + 2 C 2 H 4 → (ClC 2 H 4) 2 S

  6. Sulfonyl halide - Wikipedia

    en.wikipedia.org/wiki/Sulfonyl_halide

    In chemistry, a sulfonyl halide consists of a sulfonyl (>S(=O) 2) group singly bonded to a halogen atom. They have the general formula RSO 2 X, where X is a halogen.The stability of sulfonyl halides decreases in the order fluorides > chlorides > bromides > iodides, all four types being well known.

  7. Sulfuryl fluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl_fluoride

    Sulfuryl fluoride (also spelled sulphuryl fluoride) is an inorganic compound with the formula SO 2 F 2. It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride , being resistant to hydrolysis even up to 150 °C. [ 3 ]

  8. Bresle method - Wikipedia

    en.wikipedia.org/wiki/Bresle_method

    The solubility in water depends on the type of salt. Sodium chloride can be dissolved in cold water to a concentration of 357 g∙l −1. Not only solubility differs between salts but also the conductivity. When performing a Bresle method test, not only sodium chloride is dissolved but also all other salts present on the surface.

  9. Disulfur dichloride - Wikipedia

    en.wikipedia.org/wiki/Disulfur_dichloride

    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 ...
