Selective water (byproduct) separation from reaction mixtures stands as an important process intensification strategy for equilibrium-limited reactions. In this work, the possibility of using a high-pressure biphasic reaction media composed of a hydrophobic ionic liquid, 1-hexy-3-methylimidazolium tetracyanoborate, and carbon dioxide was explored for levulinic acid production from 1,4-butanediol. Vapor-liquid equilibrium measurements were performed for the binary (diol + CO2), ternary (diol + CO2+ IL), and quaternary systems (diol + CO2+ IL + water), at 313.2 K and pressures up to 18 MPa. The static anal. method was used in a high-pressure phase equilibrium apparatus equipped with a visual sapphire cell. The capability of the quaternary system to perform phys. water separation is discussed in this paper.
