- Abstract
The effects of ionic liquids [BMIM][NO3] on the vapor-liquid equilibria of formaldehyde-trioxanewater( FA-TOX-H2O) systems were studied. The results showed that adding [BMIM][NO3] could effectively improve the vapor-liquid equilibrium of the system, and adding a certain amount of [BMIM][NO3] could eliminate the azeotrope phenomenon. The non-random two-liquid (NRTL) model was used to fit the experimental data. The average relative deviation between experimental and calculated values of the TOX-H2O-[BMIM][NO3] ternary system was 1.32%, and that of the FA-H2O-[BMIM][NO3] ternary system was 1.74%. The vapor-liquid equilibrium of TOX-FA-H2O- [BMIM][NO3] was measured. The results showed that the addition of [BMIM][NO3] could increase the molar fraction of TOX in the vapor phase by 17.49%. The results are significant for increasing the molar fraction of TOX in vapor phase.
