Abstract
Under atmospheric pressure of the laboratory (88.94 KPa), the density (ρ), viscosity (η) and surface tension (γ) for binary mixture system of the diethylene glycol (DEG) (1) + 1,2-propanediamine (1,2-PDA) (2) were measured in different concentration ranges at T = 293.15 K ∼ 318.15 K. According to the basic data of ρ, η and γ, excess molar volumes values (VmE), viscosity deviation (Δη), surface tension deviation (Δγ), partial molar volume (V1¯...
