Role of acids in the degradation of alkanolamine during co2 and h2s removal process flv

Alkanolamines are chemical compounds that contain both hydroxyl (-OH) and amino (-NH2, -NHR, and -NR2) functional groups on an alkane backbone. The term alkanolamine is a broad class term that is sometimes used as a subclassification.



2-Aminoalcohols are an important class of organic compounds that contain both an amine and an alcohol functional groups. They are generated often by the reaction of amines with epoxides. Such compounds find a variety of industrial applications. Simple alkanolamines are used as solvents, synthetic intermediates, and high-boiling bases.

Common amino alcohols

  • Ethanolamines
  • Heptaminol
  • Isoetarine
  • Propanolamines
  • Sphingosine
  • Methanolamine (simplest amino alcohol)
  • Dimethylethanolamine
  • N-Methylethanolamine
  • Beta blockers

    A subclass of beta blockers is often called alkanolamine beta blockers. Typical examples are:

  • Propranolol
  • Pindolol
  • Natural products

    Most proteins and peptides contain both alcohols and amino groups. Two amino acids are alkanolamines, formally speaking: serine and hydroxyproline.

  • Veratridine and veratrine
  • Tropane alkaloids such as atropine
  • hormones and neurotransmitters epinephrine (adrenaline) and norepinephrine (noradrenaline)
  • 2-Amino alcohols from amino acids

    In principle, each amino acid can be hydrogenated to the corresponding 2-aminoalcohol. Examples include prolinol (from proline) and valinol (from valine).
