Densities, Viscosities, and Ultrasonic Velocity Studies of Binary Mixtures of Chloroform with Pentan-1-ol, Hexan-1-ol, and Heptan-1-ol at (303.15 and 313.15) K

Abstract

Densities, viscosities, and ultrasonic velocities of binary mixtures of chloroform with pentan-1-ol, hexan-1-ol, and heptan-1-ol have been measured over the entire range of composition at (303.15 and 313.15) K and at atmospheric pressure. From the experimental values of density, viscosity, and ultrasonic velocity, the excess molar volumes (V E), deviations in viscosity (Δη), and excess isentropic compressibility (κs E) have been calculated. The excess molar volumes (V E) are positive for all the three binaries studied over the whole composition, the excess isentropic compressibilities (κs E) are also positive except for low mole fractions of chloroform, while deviations in viscosities (Δη) are negative for all the three binary mixtures. The excess molar volumes, deviations in viscosity, and excess isentropic compressibility have been fitted to the Redlich−Kister polynomial equation. McAllister's three-body interaction model has been used to correlate the kinematic viscosities of binary liquid mixtures with mole fraction. The very recently proposed Jouyban−Acree model is used to correlate the experimental values of density, viscosity, and ultrasonic velocity at different temperatures.

Densities, Excess Molar Volumes, Ultrasonic Speeds, and Isentropic Compressibilities of Hexan-1-ol with 1,2-Dichloroethane, 1,2-Dibromoethane, and 1,1,2,2-Tetrachloroethene at (293.15 and 298.15) K

“…Due to the presence of four chlorine atoms in 1,1,2,2-TCE as compared to two in 1,2-DCE and two bromine atoms in 1,2-DBE, four H-bonds of the type Cl· · ·H-O may be formed between the OH group of hexan-1-ol polymeric entities and the 1,1,2, 2-TCE molecule as compared to two Cl· · ·H-O bonds in 1,2-DCE+hexan-1-ol and two Br· · ·H-O bonds in the 1,2-DBE + hexan-1-ol system. The unsaturation present in 1,1,2,2-TCE will also contribute towards the interaction strength of 1,1,2,2-TCE + hexan-1-ol and may be involved in the formation of the OH· · ·π electron H-bonded complex which may lead to a decrease in the molar excess volume V E [6][7][8]. The new possible H-bond interactions of the type Cl· · ·H-O and Br· · ·H-O, and π -bond interactions of the type O-H· · ·π , and weak physical intermolecular interactions in the 1,1,2,2-tetrachloroethene + hexan-1-ol system are weaker than the dipolar interactions in pure halogenated hydrocarbons and H-bonding in hexan-1-ol.…”

“…A literature survey indicates that not much work has been carried out on the study of thermodynamic properties of binary mixtures of halohydrocarbons with higher alkanols. The variations in the volumetric and acoustic properties of binary mixtures of alkanols containing haloalkanes, acetonitrile, ethylacetate, and ethenyl ethanoate, with the molecular size, shape, chain-length, and degree of molecular association of normal alkanols and branched alkanols have been reported earlier [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Alkanols are polar and self-associated liquids, and the dipolar association of alkanols decreases when they are mixed with polar compounds containing halogen atoms, due to some sort of specific intermolecular interactions between the hydroxyl oxygen of alkanols and the haloalkanes [16][17][18][19][20][21][22][23].…”
