THEORETICAL CALCULATION OF THE PHASE DIAGRAMS AND THEIR EUTECTIC POINT FOR 9 BINARY ORGANIC SYSTEM

Using the revised quasiregular model, we obtained the equations of the liquid-solid phase equilibrium curves of a binary system according to thermodynamic theory. For the 9 binary organic systems having the phase diagram with an eutectic point, we calculated the phase diagrams and their values of the eutectic point (T_0,x_(B_0)). These results agree well with the experimental values.
