Carbon dioxide absorption into biphasic amine solvent with solvent loss reduction

► Novel lipophilic amine solvent is proposed as alternative absorbent for CO2 capture. ► Thermomorphic phase transition enhances solvent regeneration at only 80 °C. ► The biphasic solvent performs high cyclic CO2 capacity and good reactivity. ► Lipophilic amine presents low degradability but high vaporisation loss. ► The vaporisation loss can be substantially reduced by condensation or scrubbing.
