Abstract
The present invention relates to novel molecules suitable to the use in the separation/removal of carbon dioxide from gaseous mixtures as liquid-phase carbon dioxide absorbers and suitable to allow the subsequent release of the absorbed carbon dioxide in form of different ionic liquids, preferentially a glycine salt with choline hexanoate, ester between glycine and hexanoic alcohol (hexyl glycinate) and glycerol ester with glycine and hexanoic acid. The present invention also relates to a method and a plant for the capture of carbon dioxide from gaseous mixtures by using an absorber for carbon dioxide in liquid phase with a heating jacket.
