ABSTRACT

Ternary liquid-liquid equilibria (LLE) data for water + furfural + cyclopentyl methyl ether (CPME) and Quaternary LLE data for water + furfural + acetic acid + CPME were measured at T = (293.15, 303.15, and 313.15) K and atmosphere pressure (p 100.25 kPa). In addition, the LLE for the quinary system of {water + furfural + acetic acid + CPME + CaCl2} were determined at 303.15K and atmosphere pressure to study salting effect on the quaternary system. Finally, based on researches of predecessors and our previous work, comparative study of various solvents including CPME, 2-methyltetrahydrofuran (2-MTHF), p-xylene, toluene, methyl iso-butyl carbinol (MIBC), tert-amyl methyl ether (TAME), and methyl tert-butyl ether(MTBE) was demonstrated.
