“…Molecular orientations of one more additive substances increases as well as increasing the orientation order of liquid crystalline phases and also the measured ultrasonic velocity should show a nature of attractive forces existing between the mixtures of given molecules. Data on some of the properties associated with refractive index, ultrasonic velocities, and surface tension find extensive application in chemical engineering process, simulation and molecular dynamics [15].The temperature variation of ultrasonic velocity and adiabatic and molar compressibility in the present case is shown in Figures 2 (a-c).The velocity exhibits an anomalous behavior at the isotropic mesophase transition, while it varies linearly in the isotropic and mesomorphic phases away from transition. The velocity shows a dip at transition.…”

We report the results of our studies on optical and thermal properties of binary mixture of compounds, viz: voriconazole and ethylene glycol. The mixture exhibits a very interesting lyotropic induced polymorphism such as sma, smc, smc* and sme phases, sequentially when the specimen is cooled from its isotropic liquid phase. They were observed using microscopic technique and also been verified from the results of optical anisotropic techniques. Ultrasonic experimental studies have been carried out to understand the molecular self assembly of the above phases at higher and lower temperatures. Optical retardation has also been discussed.

“…In chemical process industries, materials are normally handled in fluid form and as a consequence, the physical, chemical, and transport properties of fluids assume importance [1][2][3][4]. Thus data on some of the properties associated with the liquids and liquid mixtures like speed of sound, density, excess adiabatic compressibility, excess free length and excess speed of sound find extensive applications in chemical industry and engineering design [5,6].…”

“…In chemical process industries, materials are normally handled in fluid form, and as a consequence, the physical, chemical, and transport properties of fluids, assume importance. Thus, data on some of the properties associated with the liquids and liquid mixtures like density, viscosity, refractive index and ultrasonic velocity find extensive application in solution theory and molecular dynamics [2]. Such results are necessary for interpretation of data obtained from thermo chemical, electrochemical, biochemical and kinetic studies [3].…”

Densities, viscosities, refractive indices and ultrasonic velocities of the binary mixtures of Acetophenone with Propyl acetate were measured over the entire mole fractions at (303.15, 313.15 and 323.15) K. From these experimental results, excess molar volumes V E , viscosity deviation ∆η, refractive index deviation ∆n D , deviations in isentropic compressibility ∆K s and excess intermolecular free length ∆L f are calculated. The viscosity values were fitted to the models of Krishnan-Laddha and McAllister. The thermo physical properties under study were fit to the Jouyban -Acree model. The excess values were correlated using Redlich-Kister polynomial equation to obtain their coefficients and standard deviations. It was found that in all cases, the data obtained fitted with the values correlated by the corresponding models very well. The results are interpreted in terms of molecular interactions occurring in the solution.
