    en.wikipedia.org/wiki/Alkenylsuccinic_anhydrides

    However, under the "many useful applications" described for the products obtained, the use as a size has not yet been mentioned. 30% higher reaction yields were achieved with a pre-cleaned cracked petroleum distillate in an autoclave at 210 °C and it was found that the hydrolysis of the succinic anhydride can already be carried out with steam. [4]

  4. Acyl group - Wikipedia

    en.wikipedia.org/wiki/Acyl_group

    The reactivity of these five classes of compounds covers a broad range; the relative reaction rates of acid chlorides and amides differ by a factor of 10 13. [2] A major factor in determining the reactivity of acyl derivatives is leaving group ability, which is related to acidity.

  5. N-Hydroxysuccinimide - Wikipedia

    en.wikipedia.org/wiki/N-Hydroxysuccinimide

    N-Hydroxysuccinimide (NHS) is an organic compound with the formula (CH 2 CO) 2 NOH. It is a white solid that is used as a reagent for preparing active esters in peptide synthesis. It can be synthesized by heating succinic anhydride with hydroxylamine or hydroxylamine hydrochloride .

  6. Imide - Wikipedia

    en.wikipedia.org/wiki/Imide

    A general linear imide functional group. In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis.

  7. Succinic acid - Wikipedia

    en.wikipedia.org/wiki/Succinic_acid

    Succinic acid (/ s ə k ˈ s ɪ n ɪ k /) is a dicarboxylic acid with the chemical formula (CH 2) 2 (CO 2 H) 2. [5] In living organisms, succinic acid takes the form of an anion, succinate, which has multiple biological roles as a metabolic intermediate being converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain which is involved in making ...

  8. Acid anhydride hydrolases - Wikipedia

    en.wikipedia.org/wiki/Acid_anhydride_hydrolases

    Acid anhydride hydrolases are a class of hydrolase enzymes that catalyze the hydrolysis of an acid anhydride bond. [1] They are classified under EC number 3.6. One well known member of this class is GTPase .

  9. Taft equation - Wikipedia

    en.wikipedia.org/wiki/Taft_equation

    where log(k s /k CH 3) B is the ratio of the rate of the base catalyzed reaction compared to the reference reaction, log(k s /k CH 3) A is ratio of a rate of the acid catalyzed reaction compared to the reference reaction, and ρ* is a reaction constant that describes the sensitivity of the reaction series. For the definition reaction series, ρ ...
