Abstract
Abstract The viscosities (η) of 2-ethylhexan-1-amine (EHA), diglyme, triglyme, tetraglyme and EHA-diglyme/triglyme/tetraglyme non-aqueous solutions were measured by using the NDJ-5S rotational viscometer at 101 kPa. The temperatures (T) ranged from 303.2 K to 323.2 K. The mass fractions of EHA (wEHA) ranged from 0.100 to 0.900. The viscosity was modeled and the calculated results agreed well with the experiments. The effects of wEHA and T on viscosity were demonstrated on the basis of experiments and calculations. The initial absorption rates of CO2 (r) in EHA-diglyme/triglyme/tetraglyme non-aqueous solutions were measured, and the effects of viscosity, absorbent concentration and absorption rate constant of CO2 (k) on initial absorption rates were demonstrated. Our research shows that in the temperature range of 303.2 K to 323.2 K, the proposed three non-aqueous absorbents have small solution viscosities (
