Volumetric and Ultrasonic Behaviour of Acetophenone and Alcohol Mixtures

Abstract

Excess volumes and sound velocities for binary liquid mixtures of acetophenone with n-alcohols and ialcohols are measured at 303.15 K. The sound velocity and density data are used to calculate the isentropic compressibilities (k,) and deviations in isentropic compressibilities (AkJ. The values of V' are negative in all the systems except in the system, acetophenone + n-heptanol wherein the V L values are positive.Deviations in isentropic compressibilities are negative in all the systems over the entire range of composition. The data are used to explain the possible intermolecular interactions between unlike molecules. K E Y WORDS: Sound velocity. compressibility.

Excess Volumes, Speeds of Sound, Isentropic Compressibilities, and Viscosities of Binary Mixtures of Acetophenone with Chlorotoluenes and Nitrotoluenes at 303.15 K

“…can be studied by measurement of speeds of sound in liquid mixtures. Also isentropic compressibility data for the mixtures of acetophenone with 1-alkanols, benzene and substituted benzenes, and chloroethanes and chloroethenes were also reported earlier at 303.15 K. The experimental sound velocity data have been analyzed in terms of free length theory (FLT) and collision factor theory (CFT)…”

“…Thermodynamic excess properties of binary liquid mixtures have been very useful in obtaining information on the intermolecular interactions and geometrical effects in the systems. , Furthermore, thermodynamic properties of binary mixtures, containing components capable of undergoing specific interactions, exhibit significant deviation from ideality arising not only from difference in molecular size and shape but also due to structural changes. A survey of the literature has shown that V E data for the binary mixtures of acetophenone with 1-alkanols, benzene and substituted benzenes, and chloroethanes and chloroethenes have been reported. It is well-known that the ultrasound technique has a wide range of applications such as in industry and in equipment testing.…”

Acoustic, Volumetric and Viscometric Studies of Binary Liquid Mixtures of p-Chloroacetophenone with n-Alkanols at Different Temperatures

“…This shows the contraction of volume which shows the presence of strong intermolecular forces between unlike molecules than the like molecules. The intermolecular interactions are formed between the oxygen atom of -OH group of alcohols and the carbonyl group of p-chloroacetophenone 9 . Excess molar volumes (V E ) depends on some important factors like 10 .…”

Study on Molecular Interactions Using Thermodynamic Excess Properties of Binary Mixture Containing Propiophenone with 1-Propanol, 1-Butanol and 1-Pentanol at Temperatures 303.15, 308.15, 313.15 and 318.15 K

“…The excess property study has been used for the design of equipment in heat transfer, fluid mechanics, process calculation and process control. The investigations have been carried out on phenols [1][2][3] and alcohols [4,5] and more study on phenones [6][7][8][9][10][11][12] and on methyl acetate [13] has been reported. Literature survey shows that no work has been reported on these mixtures at such temperatures.…”
