liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 k. the studied systems exhibit two types of liquid-liquid equilibrium (lle) behavior. the system consisting of benzyl alcohol displays type-1 lle behavior, while a type-2 behavior is exhibited by the other s...

thermodynamic restrictions and simultaneous effects of operational conditions on the homogeneous rhodium-catalyzed carbonylation of methanol are studied in this line of research. it is shown that the general nrtl-virial model can be appropriated to study thermodynamics of the carbonylation. it is obtained that the reaction is kinetically and thermodynamically reasonable at temperatures above 42...

We found a quasi-incompressible and liquid mixture of ibuprofen, water acetone, that enables the crystallization ibuprofen particles by decreasing pressure from 15MPa to ambient (~0.1MPa). measured solubility in as function acetone/water-ratio for pressures 0.1MPa, 5.5MPa at 308K using cloud point method. Based on solubilities, binodal compositions ternary system were modelled NRTL-SAC model. T...

Aqueous two-phase system (ATPS) is considered a new method to remove heat stable salts (HSS) from flue gas desulfurizer 1,4-bis-(2-hydroxyethyl)-piperazine (BHEP). In this work, the liquid-liquid phase equilibrium data of BHEP-Na2SO4 ATPS in 303.15 – 323.15 K were measured and correlated by NRTL equation with redefined adjustable characteristic constant at different concentrations. It revealed ...
