Abstract:

Based on the method of compound synthesis, a new method of constructing the isothermal section phase diagram of ternary system is presented and the ternary C6H14O6-KCl-H2O system is taken as an example. By determinating the optical rotation of the saturated solution in the equilibrium system, the contents of the other components can be calculated, and then the isothermal section diagram of the ternary system can be constructed. The results shows that the common saturation point is as=58.5%, bs=17.4%, cs=24.1%. The general application of the method is discussed also in this paper.
