Molecular Interactions of 2-Naphthol in Binary Solvent Mixtures of Water+Methanol and Water+Ethanol with DFT Study

Abstract: Density of water, methanol, ethanol and water+methanol, water+ethanol binary solvent in pure form were experimentally measured. In these same series of solvents 2-naphthol was added to make saturated solutions of 2-naphthol at equilibrium. These saturated supernatant solutions were collected to measured densities and molalities of 2-naphthol at (293.15 to 313.15) K for comparative studies and experimental data used to calculate the excess molar volumes (V E ), apparent molar volume (V Φ ). Redlich−Kister Equa… Show more

“…The breaking of the H‐bonds results in the greater positive values of {[TBAB][Gly]} at high dilution, and the lower positive values of aq.NGB/aq.MG at higher concentration are the result of partial H‐bond breakage. At infinite dilution, the partial excess molar volume of aq.NGB/aq.MG, Vtrue¯1normalE, and that of {[TBAB][Gly]}, Vtrue¯2normalE, can be calculated as follows, using the coefficients of RK polynomial equation: 34 trueV¯1E,=A0A1+A2A3 trueV¯2E,=A0+A1+A2+A3 …”
