Diaphragm cell determination of the interdiffusion coefficient for succinonitrile + water

Interdiffusion Coefficient and Dynamic Viscosity for the Mixture 2,6-Lutidine + Water near the Lower Consolute Point

“…Below, we report interdiffusion data for 2,6-lutidine + water along the critical isopleth and along isotherms at 25.00"C and 33.00"C. Complete specification of the cross-over function, however, requires also information concerning the viscosity of the mixture [ 18,201. Viscosity data taken along the critical isopleth and isotherms at 26.969"C, 29.969"C, and 33339°C have been collected by Stein et al [32]. We have confirmed their results for the critical isopleth and report here in addition a Tew observations take along the isotherm at 25.00"C. We have also found that the data of Stein et al [32] can be readily extrapolated to match our own at 25.00"C.…”

“…The asymmetric dependence upon concentration along the isotherms has also been observed in the case of triethylamine + water by Haase and Siry [25] and in the case of succinomtrile + water by Cain et al [29]. Such asymmetry in critical phenomena is not uncommon [44].…”

Mutual diffusion in concentrated liquid solutions: A new model based on cluster theory

“…In the above equation, n is an adjustable parameter, which accounts for the omitted terms in equation 10. Hence, by combining equations (4), (6) and (13), the modified diffusion coefficient can be obtained according to:…”

“…D'Errico et al [3] used the Taylor dispersion method to measure mutual diffusion coefficients of glycerol/water at 25 °C. Other methods such as holographic interferometry, light scattering and diaphragm cell methods have been used for prediction of mutual diffusion coefficients [4][5][6]. These methods are often complex to set-up, lengthy and in many cases suffer from accuracy and reproducibility issues.…”

Phase behavior of binary mixtures composed of ethylene carbonate and various organic solvents

“…The monotectic reactions are widely known in the binary mixture of various kinds of metals, such as Zn/Pb, Zn/Bi, Cu/Pb, Na/Ca [15], and K/KCl [16,17] systems, or in the binary mixture of semiconductive materials, such as Si/Tl, Si/Pb, Si/Bi [17][18][19][20], Ga/Pb [21], Ga/Tl [20,[22][23][24], and Ga/Bi [25] systems. Today there are several papers concerning the binary mixture of organic compounds having a monotectic point; for examples, succinonitrile/water [26,27], succinonitrile/benzene [27], succinonitrile/hexamethylbenzene [7], aniline/water [15], and propylene carbonate/water [7] systems are reported as the samples for the binary mixture having a monotectic point.…”
