Ultrasonic velocity and viscosity of binary liquid mixtures

Excess Acoustical Properties and Molecular Interactions in Ternary Liquid Mixtures of 3(Meta)Methoxy Phenol, 1 Propanol and n- Hexane at 303 K, 308 K & 313 K using Ultrasonic Techniques

“…Sridevi et al [8] suggested that the negative excess compressibility has been due to closely packed molecules which causes strong interaction between the molecules (the corresponding plot is given in Fig 2). Similar conclusions were also arrived by Islam and Quadri [9]. Further the values(magnitude) of βE increases regularly when the temperature increases at each concentration of the mixtures.…”

Excess Properties and Theoretical Evaluation on Ternary Systems of 1-Pentanol in n-Hexane Solution with some Organic Compounds at 313 K Using Ultrasonic Technique

“…In the current study, the negative values (Table 1) are got for the property called excess acoustic impedance, which indicates the weak interactions are possible for the II system. This is complemented by the results of Islam et al [38]. For systems I and III, positive values are got at lower concentrations which paves the way for the presence of little stronger interactions is possible, and at the same time, negative values are obtained at higher concentrations that predict the weaker interactions, which is due to agitation of atoms among the components at an elevated working temperature of 313 K. The plot between Conc.…”

Density measurements of liquid 2-propanol at temperatures between (280 and 393)K and at pressures up to 10MPa

“…The AAD with respect to the 428 points including those measured and shown in the literature is about 0.1%. A Bias value lower than 0.02% shows a good balance of the present Golubev et al [12] Nikam et al [31] Ambrose et al [7] Islam and Quadri [23] Oswal and Putta [32] Aminabhavi et al [17] Khimenko et al [24] Paez and Contreras [33] Aminabhavi and Aralaguppi [18] Khimenko et al [25] Sakurai [34] Aminabhavi and Gopalakrishna [19] Krestov et al [26] Sovilj [35] Boned et al [8] Ku and Tu [27] Tashima and Arai [36] Contreras [20] Kubota et al [13] Tu et al [37] Costello and Bowden [21] Lee and Lin [28] Wei and Rowley [38] Egorov et al [22] Mato and Coca [29] Yaginuma et al [15] Golubev and Vagina [10] Moha-Ouchane et al [9] Zuniga-Moreno and Galicia-Luna [16] Golubev et al [11] Nagata et al [30] P / MPa 273 -300 K measurements with respect to all the available data for 2-propanol within the investigated range of temperature and pressure. The densities calculated with the developed BWR equation basically agree with the literature values within their claimed experimental uncertainty.…”
