摘要:
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. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
