Acoustic and Volumetric Properties of Mixture of (N,N-Dimethylacetamide + Ethyl Acrylate) with 1-Butanol or iso-Butanol or t-Butanol at 308.15 K

Abstract

Densities, ρ, and ultrasonic speeds, u of mixtures of 1-butanol or iso-butanol or t-butanol with equimolar mixture of (N,N-dimethylacetamide + Ethyl acrylate) over the entire composition range have been measured at T=308.15 K. Using the experimental results, deviation in ultrasonic speed, Δu, deviation in isentropic compressibility, Δks, excess molar volume, VmE, excess intermolecular free length, LfE, and excess acoustic impedance, ZE, have been calculated. The variation of these properties with composition of the mixtures has been discussed in terms of molecular interactions in these mixtures. The deviation/excess properties have been fitted to Redlich-Kister type polynomial and the corresponding standard deviations have been calculated. Negative values of VmE, Δks, and LfE and positive values of Δu, and ZE are observed over the entire composition range. The observed negative and positive values of deviation/excess properties are attributed to the strong interactions between the unlike molecules of the mixtures. Further theoretical values of sound velocity in the mixtures have been evaluated using various theories and compared with experimental sound velocities to verify the applicability of such theories to the systems studied. Theoretical ultrasonic velocity data has been used to study molecular interactions in the systems investigated.

FTIR and Ultrasonic Studies on Molecular Interactions of Ester with Butanol in the Temperature Range 303.15-318.15 K

“…Table 1 provides the experimental values of density (), viscosity () and the velocity (U) of 2 MHz sound wave for pure butanol at different temperatures. The literature values [10][11][12][13][14][15][16][17][18] for pure liquids coincide with the experimental values at all temperatures. All the experimental values decreased with increase in temperature for pure butanol.…”

“…The experimental values for pure liquids are compared with the literature values and given in Table 1 (refs [10][11][12][13][14][15][16][17][18].…”

Estimation of liquid volume fraction using ultrasound transit time spectroscopy

“…The characterisation of binary-component liquid mixtures is relevant to several biomedical and industrial applications. Ultrasound has been previously studied as a quality control tool for the manufacture of a wide-range of chemical products [1][2][3], and as a diagnostic tool to determine the molecular interaction between pure liquids, solutions and liquid mixtures [4][5][6], since it provides a non-destructive, rapid and low-cost measurement. More specifically, an experimental study conducted by Laux et al [7] investigated the suitability of aqueous sorbitol solutions as a coupling fluid between an ultrasonic transducer and the material to be examined, aimed at reducing energy loss caused by significant mismatching between these two materials.…”

“…Ultrasound has been previously studied as a quality control tool for the manufacture of a wide-range of chemical products (Dion & Burns, 2011b;Sarkar & Roy, 2009;Sreekanth, Kondaiah, Sravana Kumar, & Krishna Rao, 2012), and as a diagnostic tool to determine the molecular interaction between pure liquids, solutions and liquid mixtures (Kondaiah, Sreekanth, Sravana Kumar, & Krishna Rao, 2014;Nanda, Nanda, & Mohanty, 2012;Syal, Thakur, Literature Review 32 Chauhan, & Sharma, 2005), since it provides a non-destructive, rapid and low-cost measurement.
