AB The development of new solvents for carbon dioxide separation by chemical absorption has increased its importance during last years. Present work develops a series of studies using biphasic solvents (two liquid phases) in which amine is transferred from organic to aqueous phase during carbon dioxide chemical absorption. This type of solvents gets to reduce the amount of solvent that must be regenerated by stripping and this fact allows to reduce significantly the cost associated to this operation. The experimental results corresponding to the proposed solvent (based on the use of N-ethylpiperidine) have shown a suitable behavior when high ratios of organic phase/aqueous phase are used that allows to reduce the energy penalty. This behavior has been confirmed using bubbling and packed columns. Solvent regeneration studies showed suitable results avoiding losses in absorption rate and absorption capacity
