文摘

Various thermodynamic parameters of the binary mixtures of [diisopropylamine (DIIPA) + 2-methyl-1-propanol, + 2-propanol, and + 1-butanol] have been measured over the entire composition range and at a temperature range of (293.15 to 313.15) K. Here, the Redlich–Kister type polynomial equation is used to derive the coefficients and standard deviations. The negative value obtained for excess molar volume (V_m^E) and excess molar isentropic compressibility (K_S,m^E) shows the presence of strong molecular interactions. The calculated apparent molar volume, V_φ,1, and apparent molar compressibility, K_φ,1, predicts volume contraction of the solution with the addition of alcohol in DIIPA. The obtained excess molar volume (V_m^E) has then been correlated by using the Prigogine–Flory–Patterson (PFP) theory.
