Liquid – liquid equilibria in binary and ternary systems of phenol + hydrocarbons (n–dodecane or n–hexadecane) and water + phenol + hydrocarbons (n–dodecane or n–hexadecane) at temperatures between 298K and 353K

This study reports liquid–liquid equilibrium (LLE) and liquid–liquid–liquid (LLLE) data for binary (phenol + n- dodecane, or n -hexadecane) ternary (water phenol systems measured under atmospheric pressure. The compositions of coexisting phases were determined with analytical cloud point methods at temperatures 298 K – 353 K. Non–Random Two–Liquid (NRTL) excess Gibbs energy model was employed to correlate the systems. interaction parameters regressed using LLE data. In addition, also calculated combined isothermal vapor–liquid from literature applying NRTL–RK (Redlich–Kwong) property method. average absolute deviations in liquid mole fraction obtained NRTL (using six adjusted parameters) VLE experimental 0.006 0.014 respectively. phase equilibria hydrocarbon ( -dodecane modeled temperature range 313 573
