Using this expression we obtained the following values of the critical parameters: Tc= 567 K;
Pc= 19.35 atm; Xc= 0.241.; we have also calculated the limits of the (a+ J3) two-phase
region xa (max) and x/l (min) at 245'C to be 0.131 and 0.362, respectively. These calculated
values are in good agreement with approximate values obtained directly from discontinuities
in the observed partial enthalpies. Calorimetric measurements of the partial enthalpy in
absorption and desorption measurements at 245'C showed little evidence of hysteresis, and …
