  2. Oxidizing agent - Wikipedia

    en.wikipedia.org/wiki/Oxidizing_agent

    The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).

  3. Sulfuryl chloride - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl_chloride

    Sulfuryl chloride is not found in nature, as can be inferred from its rapid hydrolysis. Sulfuryl chloride is commonly confused with thionyl chloride, SOCl 2. The properties of these two sulfur oxychlorides are quite different: sulfuryl chloride is a source of chlorine whereas thionyl chloride is a source of chloride ions.

  4. Chlorosulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Chlorosulfuric_acid

    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

  5. Reducing agent - Wikipedia

    en.wikipedia.org/wiki/Reducing_agent

    Reducing agents and oxidizing agents are the ones responsible for corrosion, which is the "degradation of metals as a result of electrochemical activity". [3] Corrosion requires an anode and cathode to take place. The anode is an element that loses electrons (reducing agent), thus oxidation always occurs in the anode, and the cathode is an ...

  6. Thionyl group - Wikipedia

    en.wikipedia.org/wiki/Thionyl_group

    Thionyl chloride, SOCl 2, is a common reagent used in organic synthesis to convert carboxylic acids to acyl chlorides. In organic chemistry , the thionyl group is known as a sulfoxide group or sulfinyl group, and has the general structure RS(=O)R'.

  7. Sulfur dioxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_dioxide

    Sulfur dioxide is a mild but useful reducing agent. It is oxidized by halogens to give the sulfuryl halides, such as sulfuryl chloride: SO 2 + Cl 2 → SO 2 Cl 2. Sulfur dioxide is the oxidising agent in the Claus process, which is conducted on a large scale in oil refineries. Here, sulfur dioxide is reduced by hydrogen sulfide to give ...

  8. 4-Toluenesulfonyl chloride - Wikipedia

    en.wikipedia.org/wiki/4-Toluenesulfonyl_chloride

    4-Toluenesulfonyl chloride (p-toluenesulfonyl chloride, toluene-p-sulfonyl chloride) is an organic compound with the formula CH 3 C 6 H 4 SO 2 Cl. This white, malodorous solid is a reagent widely used in organic synthesis. [2] Abbreviated TsCl or TosCl, it is a derivative of toluene and contains a sulfonyl chloride (−SO 2 Cl) functional group.

  9. Inorganic nonaqueous solvent - Wikipedia

    en.wikipedia.org/wiki/Inorganic_nonaqueous_solvent

    Prominent members include sulfur dioxide, sulfuryl chloride fluoride, dinitrogen tetroxide, antimony trichloride, and bromine trifluoride. These solvents have proven useful for study highly electrophilic or highly oxidizing compounds or ions. Several (SO 2, SO 2 ClF, N 2 O 4) are gases near room temperature, so they are handled using vacuum ...
