Correction: Carbon dioxide uptake from natural gas by binary ionic liquidâwater mixtures
Correction for âCarbon dioxide uptake from natural gas by binary ionic liquidâwater mixturesâ by Kris Anderson et al., Green Chem., 2015, DOI: 10.1039/c5gc00720h
Carbon dioxide uptake from natural gas by binary ionic liquid water mixtures
[EN] Carbon dioxide solubility in a set of carboxylate ionic liquids formulated with stoicheiometric amounts of water is found to be significantly higher than for other ionic liquids previously reported. This is due to synergistic chemical and physical absorption. The formulated ionic liquid/water mixtures show greatly enhanced carbon dioxide solubility relative to both anhydrous ionic liquids and aqueous ionic liquid solutions, and are competitive with commercial chemical absorbers, such as activated N-methyldiethanolamine or monoethanolamine.The authors would like to acknowledge PETRONAS for financial support of this research, and Cytec (especially Dr Al Robertson) for supplying some of the phosphonium ionic liquids used.Anderson, K.; Atkins, MP.; Estager, J.; Kuah, Y.; Ng, S.; Oliferenko, AA.; Plechkova, NV....

A greener, halide-free approach to ionic liquid synthesis
Conventionally, ionic liquids with anions generated from simple organic acids are prepared following a metathetic procedure from a halide salt, usually a chloride. Here, we describe an efficient means of generating hydroxide solutions of the cations of interest, allowing many ionic liquids to be produced by simple acidâbase reactions, completely avoiding the use of halides.</jats:p
