Abstract In this experimental work, values of density and speed of sound of some α–amino acids viz.; glycine, L-alanine, L-valine and L-leucine with different molal concentrations of IL; 1-Butyl-3-propylimidazolium bromide ([BPim][Br]) at four working temperatures and experimental pressure p = 0.1 MPa have been determined. Using the corresponding data, different thermo physical parameters like apparent molar volume V ϕ , partial molar volume ( V ϕ 0 ), standard partial molar volume of transfer (...

Abstract null null In the present work, we investigated the effect of drug Betaine Hydrochloride (Betaine HCl) on the aggregation behavior of ethylene-1, 2-bis (N, N-dimethyl-N-tetradecylammonium bromide) (14-2-14) and tetradecyltrimethylammonium bromide (TTAB) by employing electrical conductivity and FT-IR spectroscopic techniques. Initially, synthesis of 14-2-14 is carried out in laboratory followed by determination of critical micelle concentration (CMC) through electrical conductivity measur...

Abstract The physicochemical properties of amino acids like L-Leucine and L-Serine in aqueous solution of ammonium dihydrogen Phosphate (ADP) at different temperature analysed by volumetric and acoustic methods. By using density data, apparent molar volume Vϕ, partial molar volume V ϕ 0 and standard partial molar volume of transfer Δ V ϕ 0 have been evaluated. From speed of sound data, apparent molar isentropic compression K ϕ , s apparent partial molar isentropic compression K ϕ , s 0 and parti...

Abstract Present study reports density (ρ) and ultrasonic velocity (c) for L-leucine and N-acetyl L-leucine in (0.00, 0.005, 0.01, 0.03 and 0.05) mol.kg−1 aqueous solutions of 1-hexyl-3-methylimidazolium bromide [HMIm] [Br] at T = (288.15, 298.15, 308.15 and 318.15) K. Experimental data for density and ultrasonic velocity were used to calculate the apparent molar volumes (Vϕ), the apparent molar volumes at infinite dilution ( V ϕ 0 ), partial molar isentropic compression (Kϕ,s) and partial molar...

Abstract At the temperature range of (293.15, 298.15, 303.15 and 308.15) K, the speed of sound and density values for ternary solution (Niacin+ water + Ethylene glycol (EG)/Diethylene glycol (DEG)/Triethylene glycol (TEG)) were measured at atmospheric pressure and (0.02, 0.04 and 0.06) mol·kg−1 niacin concentrations. The acoustic and volumetric properties of the mixture are analyzed though the calculated parameters i.e. Apparent Molar Volume (Vϕ), Partial Molar Volume (Vϕ0) and Partial Molar Vol...

Abstract Density and speed of sound of an aqueous solution of glycine and L-valine containing 1-dodecyl-3-methylimidazolium bromide, [C12mim] [Br], have been determined at T= (288.15 K to 308.15 K). From experimental density, the apparent molar volumes (Vϕ), the apparent molar volumes at infinite dilution ( V ϕ 0 ) and partial molar volume of transfer Δ V ϕ 0 have been calculated. The values of apparent molar volumes (Vϕ) are positive for both glycine and L-valine and increase with the increase ...

Abstract Significant information regarding the molecular interactions in the ternary solution consisting of Vitamin B3 (Niacin), water and polyethylene glycols (PEG 200/PEG 600) are attained from the calculated volumetric and acoustic parameters. Initially, the density ( ρ ) and speed of sound ( c ) for polyethylene glycols (0.1 to 0.5) mol∙kg-1 in aqueous niacin (0.01, 0.02, and 0.03) mol∙kg-1 were measured under 0.1 MPa pressure as a function of temperature at (293.15-308.15) K.
