RESUMO:

The phase behavior of 6 systems, at temperature of 25 ° C and pressure of 1 atm, was investigated in this work by the construction of their respective diagrams. System I (diesel / solution 15% glycerol / R40/R60 surfactant mixture ratio 1: 2), system II (diesel / 15% glycerol solution / R40/R60 surfactant mixture ratio 1: 1), system III (diesel / 15% glycerol solution / R60), system IV (diesel / 15% solution glycerol / R40), system V (diesel / 0% glycerol / and the VI system (diesel / glycerin solution 30% / R40 Surfactant). All systems were treated as pseudo-ternary, since no system has only 3 pure components in its composition. All systems showed the area of isotropic stability. System I presented a considerable region of gel when compared to the other systems. In analyzing the systems IV, V and VI it was realized that the higher the glycerin concentration the lower the stable microemulsion region. The tielines of the IV and V systems were found and converged to a single point. Initially it was thought that the whole region below the binodal was of 2 phases, however the studies and later photos bought the existence of 3 phases and even of only 1 phase in that region in few spaces
