It is proposed a new approach to the "structure – property" problems with usage the invariants of the fully weighted graphs for quantitative description of the critical properties of freon. A general principle of topological invariants construction of fully weighted graphs is formulated and propose two new invariants applied to calculate the critical properties of freon of methane, ethane and propane series without the involvement of experimental data and patterns.
