文摘
Molybdenum is chemically combined with other elements and usually extracted from acid leaching a residual solution of molybdenite. Understanding the behavior of the solvents is important for the optimization of the separation procedures. Therefore, binary and ternary liquid鈭抣iquid equilibria (LLE) were measured for a mixture of chloroform, acetylacetone, and water at (293.15 to 333.15) K and atmospheric pressure (101.3 卤 0.7 kPa). The solid鈭抣iquid equilibrium (SLE) between chloroform and acetylacetone was also determined by visual techniques. This system has a single eutectic point. The experimental LLE and SLE data were well-correlated by the nonrandom two-liquid (NRTL) and universal quasichemical activity coefficient (UNIQUAC) models. In addition, the excess molar volume (VE) and refractivity (nD) for the binary chloroform + acetylacetone mixture were measured at 298.15 K over the entire composition range. The experimental data were satisfactorily fit using the Redlich鈭扠ister polynomial.
