WebApr 3, 2024 · Finally, the tertiary amine reacts with alkyl halides to form quaternary ammonium salts. (Image to be added soon) Acylation - Aliphatic and aromatic primary and secondary amines (which contain replaceable hydrogen atoms) react with an acid chloride, acid anhydride and esters to form substituted amides. WebApr 12, 2024 · Their faster reaction rates with CO2 and high capture efficiencies at low CO2 partial pressures are advantageous. In contrast, tertiary amines more effectively react with CO2 at lower temperatures, capturing up to 1 CO2 per amine; initially and unexpectedly, carbonate and bicarbonate species are initially formed simultaneously.
