文摘

Density and viscosity data for the binary system of 1,2-ethanediamine (EDA) + poly(ethylene glycol) 200 (PEG) at T = (303.15, 308.15, 313.15, 318.15, and 323.15) K were determined over the whole concentration range under atmospheric pressure as functions of composition. From the experimental data, the excess molar volume and viscosity deviation, respectively, were calculated and fitted to a Redlich–Kister equation to obtain the coefficients and estimate the standard deviations between the experimental and calculated quantities. At the same time, apparent molar volumes and partial molar volumes were also calculated. In addition, the intermolecular interaction of PEG with EDA is discussed on the basis of FTIR and UV–vis spectral results.
