  2. Haloform reaction - Wikipedia

    en.wikipedia.org/wiki/Haloform_reaction

    haloform-reaction. RSC ontology ID. RXNO:0000689. In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C (=O)CH3, where R can be either a hydrogen atom, an alkyl or an aryl ...

  3. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte. A similar galvanic reaction is exploited in primary cells to generate a useful electrical voltage to power ...

  4. Friedel–Crafts reaction - Wikipedia

    en.wikipedia.org/wiki/Friedel–Crafts_reaction

    The reaction proceeds through generation of an acylium center. The reaction is completed by deprotonation of the arenium ion by AlCl 4 −, regenerating the AlCl 3 catalyst. However, in contrast to the truly catalytic alkylation reaction, the formed ketone is a moderate Lewis base, which forms a complex with the strong Lewis acid aluminum ...

  5. Desulfonylation reactions - Wikipedia

    en.wikipedia.org/wiki/Desulfonylation_reactions

    Desulfonylation reactionsare chemical reactions leading to the removal of a sulfonylgroup from organic compounds. As the sulfonyl functional group is electron-withdrawing,[1]methods for cleaving the sulfur–carbon bonds of sulfones are typically reductive in nature. Olefination or replacement with hydrogenmay be accomplished using reductive ...

  6. Phenol - Wikipedia

    en.wikipedia.org/wiki/Phenol

    Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C6H5OH. [ 5 ] It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH).

  7. Rust converter - Wikipedia

    en.wikipedia.org/wiki/Rust_converter

    Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...

  8. Phenol formaldehyde resin - Wikipedia

    en.wikipedia.org/wiki/Phenol_formaldehyde_resin

    Infobox references. Phenol formaldehyde resins (PF) (phenolic resins or phenoplasts [ 1 ]) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, PFs were the first commercial synthetic resins. They have been widely used for the production of molded products including ...

  9. Wolff–Kishner reduction - Wikipedia

    en.wikipedia.org/wiki/Wolff–Kishner_reduction

    RXNO:0000226. The Wolff–Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into methylene groups. [1][2] In the context of complex molecule synthesis, it is most frequently employed to remove a carbonyl group after it has served its synthetic purpose of activating an intermediate in a preceding step.
