Salt Effect on the High-Pressure Multiphase Behavior of the Ternary System (Ethene + Water + 2-Propanol)

Abstract

At temperatures from (289 to 353) K, the ternary system (ethene + water + 2-propanol) is known to exhibit a region of liquid−liquid−vapor (L1L2V) equilibria at elevated pressures that is bordered by the lower ((L1 = L2)V) and upper (L1(L2 = V)) critical end point lines. This particular demixing effect is commonly known as “salting out by a supercritical gas”. In this work, the effect of adding different electrolytes on the pressure of both critical end points at (293 and 333) K is investigated.
