Data,
20, 41). Solid lines: calculated with Equation 10.18, dashed line: calculated with
the Krichevsky equation (Equation 10.12), on Figure 10.1a, the dashed line (A) represents
results obtained with Equation 10.11 when the activity coefficients of the mixed solvents are
expressed through the two-sufix Margules equations: (a) oxygen (2) in 1-propanol (1) - water
(3) at 40ºC; (b) nitrogen (2) in 2-propanol (1) - water (3) at 40ºC; (
