Abstract
The study of liquid-liquid equilibrium is extremely important for planning and development of projects, as well as providing support for analysis and selection of unit operations and industry processes. The present work aims to develop a methodology for the data collection of liquid-liquid equilibrium from the density of mixtures of the ternary system, water-acetone-chloroform. The mass fractions of the three components were obtained by the liquid-liquid extraction experimental method, as well as the density, which was determined by the gravimetric method of pycnometry. Through the modeling developed, it was possible to calculate the molar volume of excess of each binary, from the component composition data, to predict the density of the ternary mixture. In the same way, the substances present in the solution could be quantified by the experimental density. Through the analysis of the results obtained throughout the work, the modeling developed proved to be quite effective
