Excess Molar Quantities of Binary Mixture of Dipropyl amine with Aliphatic Alcohols at 298.15 K

Abstract

Refractive indices (nD), viscosities (η) and densities (ρ) were deliberated for the binary mixtures created by dipropyl amine with 1-octanol, 1-heptanol, 1-hexanol, 1-pentanol and tert-pentyl alcohol at temperature 298.15 K over the perfect installation extent. The function of Redlich-Kister were used to calculate and renovated of the refractive index deviations (∆nD), viscosity deviations (ηE), excess molar Gibbs free energy (∆G*E) and excess molar volumes (VmE) The standard errors and coefficients were respected by this function. The values of ∆nD, ηE, VmE and ∆G*E were plotted against mole fraction of dipropyl amine. In all cases the obtained ηE, ∆G*E, VmE and ∆nD values were negative at 298.15K. Effect of carbon atoms number in the chain of alcohol and hydroxyl groups' position on molecular interactions in these mixtures has also been discussed.

"Excess and deviations properties for the binary solvent mixtures of tetrahydrofurfuryl alcohol with some aromatic hydrocarbons at 298.15K "

“…fluids flow, heat and mass transfer) of mixtures systems are important in many chemical industries, solution theories and biological processes [1][2][3][4]. Moreover, for profound understanding the interaction properties between component molecules of liquid mixture, in terms of nature, strength of interaction and behavior of solution, the experimental excess properties are very important [5][6][7][8].…”
