In a 1,4-dioxane-water mixture at 293, 295, and 297 K, throughout a wide range of concentration, the density, viscosity, and ultrasonic velocity of synthesised Schiff base 1,3-benzothiazol-2-amine and its substituted derivatives have been examined. The current work involved the analysis of acoustical parameters such as ultrasonic velocity (V), adiabatic compressibility (βs), apparent molar volume (ϕv), and intermolecular free length (Lf), which represent structural properties.

The measured data were used to calculate various useful thermodynamic parameters. A complete characterization of any mixture can be performed by means of these thermodynamic properties. The apparent molar volume, ϕv, partial molar volume, $\phi _v^0$ and partial molar isobaric expansibilities, $\phi _E^0,$ were calculated using density data.

The examination of a drug in water and other aqueous systems gives insight into the chemistry of biological systems. This work aims to study the physico-chemical properties of chlorpheniramine maleate (drug) in water and aq-MeOH/EG (mono/dihydric alcohols) systems at different temperatures by using different techniques. Densities and viscosities of chlorpheniramine maleate in water and also in MeOH/EG aqueous solutions have been measured over a temperature range of 298.15 to 318.15 K.

ABSTRACT <strong>Objective:</strong> Main objective is to study the solute solvent interactions in different heterocyclic drugs with the help of various acoustic properties. <strong>Method:</strong> The values of ultrasonic velocity are measured by using ultrasonic interferometer for solution of different concentrations of heterocyclic drugs (Lamivudine, Simvastatin) in 70% 1,4-dioxane as a solvent at 303.15 K. This experimental data is used to explore the acoustic properties like as intermolecular free length (Lf ), adiabatic compressibility (b s), apparent molal volume (ϕv), s

The concept of Frank’s hypothesis (that is the effect of large tetra alkyl ammonium iodides on the solvent structure, especially in the ion – ion and ion – solvent interactions) was found to be not applicable when water was replaced by one of organic solvent. That is, if study involves ion- ion and ion – solvent interactions in 1, 3 – Butane diol – DMF solvent mixture. The densities of these mixture and some adding tetra alkyl ammonium iodide salts solutions at different concentrations (0.02 – 0.14 M) have been determined at 298.15 K using Magnetic Float Densitometer technique.

To this point we have developed a method of dealing with processes involving for the most part material (phases) of fixed composition. To progress further, we need to develop ways of dealing with the properties of dissolved substances, and with phases of variable composition. In other words, we need to deal with solutions. We have seen that the properties of homogeneous substances (usually, but not necessarily pure) are either total or molar properties (neglecting, as usual, specific properties). But obviously substances change drastically when they dissolve. How can we obtain properties for t

In order to examine the non-ideal behaviour of a liquid, it is crucial to conduct investigations. To determine excess properties, a range of measurable properties can be utilized in experimental calculations. Major characteristics to consider in binary and ternary mixtures include density and apparent molar volume. From a thermodynamic standpoint, several combination characteristics, various thermodynamic features, such as partial molar volumes, at infinite dilution, hold great significance. The purpose of this review is to provide a summary of recent research on the acoustics and thermodynami

The transfer of liquid hydrocarbons into water is accompanied by a large decrease in volume at 25 °C and atmospheric pressure, with typical values for ΔV°tr of — 2.0 ml mol methylene−1. Considering the large amount of apolar surface that is exposed when a globular protein unfolds, the hydrocarbon transfer results imply that the change in volume accompanying the unfolding process (ΔV°obs) should be highly negative under these conditions. However, experimental data on the pressure denaturation of proteins typically yield relatively small values of ΔV°obs at atmospheric pressure and 25 °C. We ana
