Refractive indices, viscosity at 298 K, 303 K and 308 K and ultrasonic velocity at 298 K of five binary mixtures of ethyl chloroacetate (ECA) with benzene, toluene, 1,4-dimethyl benzene (p-xylene), 1,3,5-trimethyl benzene (mesitylene), and methoxybenzene (anisole) have been evaluated theoretically using various empirical relations applicable to binary mixtures. Relative merits and interrelation in these mixing rules have been discussed. An excellent agreement has been found between the experimental values with the respective values obtained from the mixing rules. Also, the extended statistical theory of Flory (FST) has been used to predict the surface tension of five binary systems at 298K. The values of surface tension thus obtained have been utilized to compute ultrasonic velocity using Auerbach relation. Theoretical values have been compared with the experimental values. The results have been discussed in terms of average percentage deviation (APD).

Abstract


Refractive indices, viscosity at 298 K, 303 K and 308 K and ultrasonic velocity at 298 K of five binary mixtures of ethyl chloroacetate (ECA) with benzene, toluene, 1,4-dimethyl benzene (p-xylene), 1,3,5-trimethyl benzene (mesitylene), and methoxybenzene (anisole) have been evaluated theoretically using various empirical relations applicable to binary mixtures. Relative merits and interrelation in these mixing rules have been discussed. An excellent agreement has been found between the experimental values with the respective values obtained from the mixing rules. Also, the extended statistical theory of Flory (FST) has been used to predict the surface tension of five binary systems at 298K. The values of surface tension thus obtained have been utilized to compute ultrasonic velocity using Auerbach relation. Theoretical values have been compared with the experimental values. The results have been discussed in terms of average percentage deviation (APD).
