Ternary liquid—liquid equilibria for acetonitrile—ethanol—cyclohexane and acetonitrile—2-propanol—cyclohexane

Model for phase equilibria correlation and prediction. Characteristics and application to binary liquid—vapor and binary, ternary and quaternary liquid—liquid equilibria

“…water-chloroform, water-ethylacetate and waterbenzene) leading to an indetermination of the parameter k13 corresponding to that binary pair, existing several values of this k suitable to correlate the corresponding BLLE (Ruiz, 1982). There are several ways to improve the prediction (Marina and Tassios, 1973;Anderson and Prausnitz, 1978;Schulte et al, 1980;Nagata and Katoh, 1980). In the present work we have fixed these parameters k assuring an adequate behaviour of the GEM as a function of the composition.…”

Ternary (liquid+liquid) equilibria for (acetonitrile+ethanol or 1-propanol+heptane) and (aniline+methanol+cyclohexane)

“…(11) Mutual solubilities for (aniline + cyclohexane) and (methanol + cyclohexane) at T = (298.15 2 0.02) K agreed well with previous results. (2,9) The liquid-phase compositions of ternary equilibrated samples were analysed with a thermal conductivity g.l.c. (Shimadzu g.l.c., GC-8A) and an electronic integrator (Shimadzu Chromatopac, C-R6A).…”

(Liquid+liquid) equilibria for (methanol+aniline or acetonitrile+cyclohexane+heptane) at the temperature 298.15 K

“…(1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11) This paper reports results for (acetonitrile + cyclohexane + heptane), (methanol + aniline + cyclohexane + heptane), and (methanol + acetonitrile + cyclohexane + heptane), measured at the temperature T = 298.15 K. The experimental results are correlated with the two activity-coefficient models: extended UNIQUAC and modified Wilson. (12,13) Phase-equilibrium results for the binary and (14) (acetonitrile + methanol) at T = 328.15 K; (15) (cyclohexane + heptane) T = 298.15 K; (16) mutual solubilities at T = 298.15 K: (methanol + cyclohexane); (17) (methanol + heptane); (18) (aniline + cyclohexane); (19) (aniline + heptane); (19) (acetonitrile + cyclohexane); (20) and (acetonitrile + heptane); (5) and ternary tie-line results at T = 298.15 K: (methanol + aniline + heptane); (19) (methanol + aniline + cyclohexane); (19) (aniline + cyclohexane + heptane); (21) (methanol + cyclohexane + heptane); (6) (methanol + acetonitrile + cyclohexane); (17) and (methanol+acetonitrile+heptane).…”
