  2. Aspirin - Wikipedia

    en.wikipedia.org/wiki/Aspirin

    The synthesis of aspirin is classified as an esterification reaction. Salicylic acid is treated with acetic anhydride, an acid derivative, causing a chemical reaction that turns salicylic acid's hydroxyl group into an ester group (R-OH → R-OCOCH 3). This process yields aspirin and acetic acid, which is considered a byproduct of this

  3. Acetylation - Wikipedia

    en.wikipedia.org/wiki/Acetylation

    Salicylic acid is acetylated to form aspirin. In chemistry, acetylation is an organic esterification reaction with acetic acid. It introduces an acetyl group into a chemical compound. Such compounds are termed acetate esters or simply acetates. Deacetylation is the opposite reaction, the removal of an acetyl group from a chemical compound.

  4. Henderson–Hasselbalch equation - Wikipedia

    en.wikipedia.org/wiki/Henderson–Hasselbalch...

    The Henderson–Hasselbalch equation can be used to estimate the pH of a buffer solution by approximating the actual concentration ratio as the ratio of the analytical concentrations of the acid and of a salt, MA. The equation can also be applied to bases by specifying the protonated form of the base as the acid. For example, with an amine,

  5. Acetic anhydride - Wikipedia

    en.wikipedia.org/wiki/Acetic_anhydride

    Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with ...

  6. Acetoacetic acid - Wikipedia

    en.wikipedia.org/wiki/Acetoacetic_acid

    Infobox references. Acetoacetic acid (IUPAC name: 3-Oxobutanoic acid, also known as Acetonecarboxylic acid or Diacetic acid) is the organic compound with the formula CH 3 COCH 2 COOH. It is the simplest beta- keto acid, and like other members of this class, it is unstable.

  7. Hydrolysis - Wikipedia

    en.wikipedia.org/wiki/Hydrolysis

    Hydrolysis (/ haɪˈdrɒlɪsɪs /; from Ancient Greek hydro- 'water' and lysis 'to unbind') is any chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile. [1]

  8. Acetyl group - Wikipedia

    en.wikipedia.org/wiki/Acetyl_group

    In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH3 and the structure −C (=O)−CH3. It is sometimes represented by the symbol Ac[5][6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group. An acetyl group contains a methyl group ...

  9. Wacker process - Wikipedia

    en.wikipedia.org/wiki/Wacker_process

    Wacker process. The Wacker process or the Hoechst-Wacker process (named after the chemical companies of the same name) refers to the oxidation of ethylene to acetaldehyde in the presence of palladium (II) chloride and copper (II) chloride as the catalyst. [1] This chemical reaction was one of the first homogeneous catalysis with organopalladium ...
