包含苯、萘的二元和三元混合物折射率的实测数据已有不少报导,根据这些数据还提出了计算的经验方程。利用这些方程,又可反过来推算混合物的组分。二元系统的某热力学性质G和其组分的关系可用式(1)表之。 G=x_1G_1+x_2G_2+x_1x_2/[A+B(x_1-x_2)] (1)
The measured data of the refractive indices of binary and ternary mixtures containing benzene and naphthalene have been reported. Based on these data, empirical equations of calculation are also proposed. Using these equations, the composition of the mixture can in turn be extrapolated. The binary system of a thermodynamic properties of G and its components can be used formula (1) table. G = x_1G_1 + x_2G_2 + x_1x_2 / [A + B (x_1-x_2)] (1)
