Abstract
The liquid-liquid coexistence curve, the isobaric heat capacity per unit volume and the turbidity for the binary solution of nitrobenzeneâ¯+â¯n-pentadecane have been measured at various temperatures. The upper consolute mole fraction xc of nitrobenzene and the upper consolute temperature Tc of the binary solution were determined to be xcâ¯=â¯0.696 and Tcâ¯=â¯307.298â¯K, respectively. The values of the critical exponents related to the width of the coexistence curve, the heat capacity, the osmotic compressibility and the correlation length were deduced and found to be in good agreements with that of the 3-D Ising universality. With the heat capacity data the asymmetric behavior of the diameter of the coexistence curve was studied in terms of the complete scaling theory. The critical amplitudes related to the above four quantities were used to calculate the universal scaling ratios and to confirm their theoretical predictions.
