  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)

    This improper name persists, especially in elementary textbooks. In biology, the unit "%" is sometimes (incorrectly) used to denote mass concentration, also called mass/volume percentage. A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because ...

  4. Mass concentration (chemistry) - Wikipedia

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

    In chemistry, the mass concentration ρ i (or γ i) is defined as the mass of a constituent m i divided by the volume of the mixture V. [1]= For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture.

  5. Conversion (chemistry) - Wikipedia

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

    Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...

  6. 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.

  7. 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.

  8. 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

  9. Sulfuryl - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl

    In inorganic chemistry, the sulfuryl group is a functional group consisting of a sulfur atom covalently bound to two oxygen atoms (S(=O) 2 X 2). It occurs in compounds such as sulfuryl chloride , SO 2 Cl 2 and sulfuryl fluoride , SO 2 F 2 .
