Vapour–liquid equilibrium study of binary mixtures of aniline with isopropanol, n-butanol and ethylene glycol at the local atmospheric pressure

Experimental Study and Modeling of the Isothermal VLE Properties of the Supercritical C3H8 + Aniline Mixture at High Temperatures and High Pressures

“…Experimental activity coefficient γ i of components have been calculated using the measured VLE data ( PTxy ) as , γ i = y i P x i P i s a t where P i sat is the vapor-pressure of pure component , (aniline), x i and y i are the liquid and vapor phase mole fraction of component i in equilibrium state, P is the measured total pressure of the mixture (Table S1), γ i is the activity coefficient of component i in the liquid phase. Antoine type equation for aniline has been used to calculate of the vapor-pressure P i sat ln ⁡ P S false( normalkPa false) = 14.6574 − 3857.52 T false( normalK false) − 73.13 Derived values of the activity coefficient of aniline γ i in the liquid phase as a function of temperature at selected isobars are depicted in Figure .…”

“…in aniline at 298.15 K and atmospheric pressure. High-pressure solubility data of methane in aniline has been reported by Ventura et al Mali et al reported isobaric VLE ( Txy ) behavior of the binary systems of aniline with 2-propanol, n -butanol, and ethylene glycol at atmospheric pressure (96.15 kPa) using a dynamic V–L circulating still. The measured data were fitted to Wilson, NRTL, and UNIQUAC activity coefficient models to estimate the binary interaction parameters.…”

“…As one can see, the rate of the solubility of CH 4 in aniline considerable higher than C 3 H 8 .Activity Coefficients. Experimental activity coefficient γ i of components have been calculated using the measured VLE data (PTxy) as12,13…”
