In their Full Paper on page 1724 ff., F. Mani et al. demonstrate that CO2 absorption and amine regeneration can be successfully carried out in a closed cycle process based on 2-amino-2-methyl-1-propanol and piperazine in 2-ethoxyethanol. These solvents, by virtue of their rather low desorption temperature and thermal and oxidative stability, may reduce the high operational costs of the conventional CO2 capture process based on aqueous amines. The pure CO2 recovered from the desorption step can be easily converted into an alkyl carbonate via the intermediate 2-amino-2-methyl-1-propanol carbamate and its reaction with an alcohol (methanol, ethanol, or ethylene glycol). The same reaction also occurs after replacing carbamate with the carbonate derivative of the protonated 2-amino-2-methyl-1-propanol.
