where n is the number of experimental data points and k is the
number of fitted parameters.
Vm
E of each binary system at different temperatures from
(293.15 to 318.15) K are shown in Figure 2, and those of the
three binary systems at T = 298.15 K are shown in Figure 3. As
illustrated in Figure 2, the excess molar volumes for the three
systems are all negative and the absolute values change in
growing trends with the increase of temperature. The maximum
values of Vm
E are at the mole fractions of 1,1′-bicyclohexyl (x1)
from 0.4 to 0.5. As shown in Figure 3, the absolute values of
Vm
E are on the order of Vm
E(c) < Vm
E(b) < Vm
E(a), where a, b,
and c denote the binary systems of 1,1′-bicyclohexyl with
