ABSTRACT
The mass fraction solubilities of benzene, toluene, o-xylene, m-xylene, and p-xylene in 1-buty-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) ionic liquid in the temperature range from (298.21 to 353.15) K and the mass fraction solubility of [BMIM][BF4] in benzene, toluene, o-xylene, m-xylene, and p-xylene in the temperature range from (298.47 to 353.45) K have been measured using a cloud-point method. Measured solubility values S were correlated as a function of temperature by a second-order polynomial. The calculated solubility values 100S of benzene, toluene, o-xylene, m-xylene, and p-xylene in [BMIM][BF4] at 320 K are 0.0995, 0.1361, 0.1425, 0.0883, and 0.1238, respectively. The calculated solubility values 100S of the ionic liquid in benzene, toluene, o-xylene, m-xylene, and p-xylene at 320 K are 0.1935, 0.2027, 0.2506, 0.1492, and 0.1654, respectively. The overall uncertainty was estimated to be about 4 % at 310 K for the first half of the work and decreased with increasing temperature and was estimated in a similar way to be 3.5 % for the second half of the work.
