Viscosity, activation energy, and CO2 diffusion coefficient of non-aqueous solutions of 3-methylamino propylamine (MAPA)/3-dimethylamino-1-propylamine (DMAPA) with polyethylene glycol (PEG200)

Abstract

In this paper, viscosity (η) of 3-Methylaminopropylamine (MAPA)/3-dimethylamino-1-propylamine (DMAPA) with polyethylene glycol (PEG200) was detected over the range of (from 303.2 K to 323.2 K) temperature with amine mass fractions in the range of (from 0.30 to 0.60) at atmospheric pressure. The dependence of η on temperature and mass fractions was clarified. On the experimental basis, the activation energy (Ea) and CO2 diffusion coefficient (D CO2) in MAPA/DMAPA-PEG200 non-aqueous solutions were deduced.
