In this paper, we measured the viscosities (η) data of aqueous solutions of 1-(2-Hydroxyethyl)-piperidine (1-(2-HE)PP) by using NDJ-5S digital rotary viscometer. The mass fractions of 1-(2-HE)PP ranged from 0.1 to 1, and the experimental temperatures were 303.2 K, 313.2 K and 323.2 K respectively. The effects of temperature and W1_(2-HE)pp on viscosity were demonstrated. Based on the experimental data of viscosity, we deduced the activation energy (Ea) and CO 2 diffusion coefficient (Dco 2 ) of 1-(2-HE)PP aqueous solutions.
