• amine
  • Amine blends that are activated by concentrated piperazine are used extensively in commercial CO2 removal for carbon capture and storage (CCS) because piperazine advantageously allows for protection from significant thermal and oxidative degradation at typical coal flue gas conditions. (wikipedia.org)
  • nonetheless, the CO2 absorption rate, heat of absorption, and solvent capacity are increased through the addition of piperazine to amine gas treating solvents, the most common of which is MDEA due to its unmatched high rate and capacity efficiency. (wikipedia.org)
  • To combine the advantages of MDEA and the smaller amines, MDEA is usually mixed with a catalytic promoter such as piperazine, PZ, or a fast reacting amine such as MEA to retain reactivity, but lower regeneration costs. (wikipedia.org)
  • nitrogen atoms

  • 2,5-Diketopiperazine, also known as piperazine-2,5-dione and as the cyclodipeptide cyclo(Gly-Gly), is an organic compound and the smallest cyclic dipeptide that consists of a six-membered ring containing two amide linkages where the two nitrogen atoms and the two carbonyls are at opposite positions in the ring. (wikipedia.org)
  • A diketopiperazine (DKP), also known as a dioxopiperazine or piperazinedione, is a class of organic molecules in which the two nitrogen atoms of a piperazine 6-membered ring are part of amide linkages. (wikipedia.org)
  • DPKs can be visualized as α-amino amides where the nitrogen atoms are constrained into a six membered ring: As a result of the structural similarities of DKPs to peptides and their appearance in biologically active natural products, medicinal chemists have been inspired to use DKPs to circumvent the poor physical and metabolic properties of peptides in the course of drug discovery.
