Solubility Parameters of Solvent Blends

Since the solubility parameters of a large number of solvents are known one can calculate the values for a solvent blend from Equation 19.2 where O is the volume fraction of each solvent component in the blend.

The use of the solubility envelope, together with the volumetric additivity rule for calculating solubility parameters of solvent blend and the solvent evaporation model described previously, allows an approximate assessment whether phase separation will take place or not during solvent evaporation. 

Solubility parameters of solvent blends are calculated using the linear relationship ...
