• acid
  • In 1957, Zilkha reported a new simpler method based on adding amines to crotonic acid and then catalytically hydrogenolysing the product to produce BABA. (wikipedia.org)
  • Commercial glyoxal is prepared either by the gas-phase oxidation of ethylene glycol in the presence of a silver or copper catalyst (the Laporte process) or by the liquid-phase oxidation of acetaldehyde with nitric acid. (wikipedia.org)
  • Glyoxal may be synthesized in the laboratory by oxidation of acetaldehyde with selenious acid. (wikipedia.org)
  • One pathway degrades the chlorocarbon to acetaldehyde via chloroacrylic acid. (wikipedia.org)
  • alcohol
  • A classic example for favoring the keto form can be seen in the equilibrium between vinyl alcohol and acetaldehyde (K = [enol]/[keto] ≈ 3 × 10−7). (wikipedia.org)
  • However, it is reported that in the case of vinyl alcohol, formation of a stabilized enol form can be accomplished by controlling the water concentration in the system and utilizing the kinetic favorability of the deuterium produced kinetic isotope effect (kH+/kD+ = 4.75, kH2O/kD2O = 12).

  • Metaldehyde acts on the pest by contact or ingestion, and the aqueous environment inside the pest's cells readily hydrolyzes metaldehyde into acetaldehyde, the molecule associated with an alcohol hangover. (wikipedia.org)
  • found
  • Like other pyridine derivatives, 2-methylpyridine is often reported as an environmental contaminant associated with facilities processing oil shale or coal, and has also been found at legacy wood treatment sites. (wikipedia.org)
