CO₂ Capture in Ionic Liquids Based on Amino Acid Anions With Protic Side Chains: a Computational Assessment of Kinetically Efficient Reaction Mechanisms.

ABSTRACT: Absorption and capture of CO₂ directly from sources represents one of the major tools to reduce its emission in the troposphere. One of the possibilities is to incorporate CO₂ inside a liquid exploiting its propensity to react with amino groups to yield carbamic acid or carbamates. A particular class of ionic liquids, based on amino acids, appear to represent a possible efficient medium for CO₂ capture because, at difference with current industrial setups, they have the appeal of a biocompatible and environmentally benign solution. We have investigated, by means of highly accurate computations, the feasibility of the reaction that incorporates CO₂ in an amino acid anion with a protic side chain and ultimately transforms it into a carbamate deriva
