Abstract

Steric bulk controls CO ₂ absorption: N-substituted amino acid salts in poly(ethylene glycol) reversibly absorb CO ₂ in nearly 1:1 stoichiometry. Carbamic acid is thought to be the absorbed form of CO ₂; this was supported by NMR and in situ IR spectroscopy, and DFT calculations. The captured CO ₂ could be converted directly into oxazolidinones and thus CO ₂ desorption could be sidestepped.
