Novel ionic liquid analogs formed by triethylbutylammonium carboxylate-water mixtures for CO 2 absorption

This work presents ten ionic liquid analogs of triethylbutylammonium carboxylate and water as CO2 absorbents. The mixtures are liquids with relatively low viscosities at ambient temperature. The absorption experimental results have shown that each of them has fast absorption rate and large absorption capacity of CO2.
