  2. Butyraldehyde - Wikipedia

    en.wikipedia.org/wiki/Butyraldehyde

    Butyraldehyde, also known as butanal, is an organic compound with the formula CH 3 (CH 2) 2 CHO. This compound is the aldehyde derivative of butane . It is a colorless flammable liquid with an unpleasant smell.

    en.wikipedia.org/wiki/List_of_drugs_by_year_of...

    In 1832 produced chloral hydrate, the first synthetic sleeping drug. In 1833 French chemist Anselme Payen was the first to discover an enzyme, diastase. In 1834, François Mothes and Joseph Dublanc created a method to produce a single-piece gelatin capsule that was sealed with a drop of gelatin solution.

  4. Isobutyraldehyde - Wikipedia

    en.wikipedia.org/wiki/Isobutyraldehyde

    It is an aldehyde, isomeric with n-butyraldehyde (butanal). [1] Isobutyraldehyde is made, often as a side-product, by the hydroformylation of propene. Its odour is described as that of wet cereal or straw. It undergoes the Cannizaro reaction even though it has alpha hydrogen atom. It is a colorless volatile liquid.

  5. Butyric acid - Wikipedia

    en.wikipedia.org/wiki/Butyric_acid

    In industry, butyric acid is produced by hydroformylation from propene and syngas, forming butyraldehyde, which is oxidised to the final product. [7] H 2 + CO + CH 3 CH=CH 2 → CH 3 CH 2 CH 2 CHO butyric acid. It can be separated from aqueous solutions by saturation with salts such as calcium chloride.

  6. γ-Hydroxybutyraldehyde - Wikipedia

    en.wikipedia.org/wiki/Γ-hydroxybutyraldehyde

    It is a chemical intermediate in the biosynthesis of the neurotransmitter γ-hydroxybutyric acid (GHB) from 1,4-butanediol (1,4-BD). [2] Like 1,4-BD, it also behaves as a prodrug to GHB when taken exogenously.

  7. Isobutanol - Wikipedia

    en.wikipedia.org/wiki/Isobutanol

    Isobutanol is produced by the carbonylation of propylene. Two methods are practiced industrially, hydroformylation is more common and generates a mixture of isobutyraldehyde and butyraldehyde: CH 3 CH=CH 2 + CO + H 2 → CH 3 CH 2 CH 2 CHO. The reaction is catalyzed by cobalt or rhodium complexes.

  8. Acetaldehyde - Wikipedia

    en.wikipedia.org/wiki/Acetaldehyde

    Demand has been impacted by changes in the production of plasticizer alcohols, which has shifted because n-butyraldehyde is less often produced from acetaldehyde, instead being generated by hydroformylation of propylene. Likewise, acetic acid, once produced from acetaldehyde, is made predominantly by the lower-cost methanol carbonylation ...

  9. Butyryl-CoA - Wikipedia

    en.wikipedia.org/wiki/Butyryl-CoA

    Butyryl-CoA (or butyryl-coenzyme A, butanoyl-CoA) is an organic coenzyme A-containing derivative of butyric acid. [1] It is a natural product found in many biological pathways, such as fatty acid metabolism (degradation and elongation), fermentation, and 4-aminobutanoate (GABA) degradation.
