Prediction of Interactions between Binary Mixtures of Aliphatic Amines and Aliphatic Acetates

Abstract

The refractive indices (n) of aliphatic amines and aliphatic acetates were measured at different temperatures (293.15, 298.15, 303.15, 308.15 and 313.15 K) on the entire composition as CO2 capture is a fast-developing field with amine based technologies due to their reversible reaction with CO2. The aliphatic amines selected were diethylenetriamine, dibutylamine and tributylamineand methyl acetate, ethyl acetate, propyl acetate, butyl acetate and pentyl acetate respectively. All the possible binary mixtures of these aliphatic amines and acetates were taken for determining the experimental refractive indices and various empirical correlations like Arago-Biot, Gladstone-Dale, Lorentz-Lorenz, Heller, Weiner, Newton and Erying-John were applied to experimental data for estimating theoretical value of refractive indices. To evaluate the standard deviation, Redlich-Kister polynomial equation was applied to the measured refractive indices data.
