WebThe “Solvent Settings” offers the possibility to specify the chosen solvent base. This is useful, if the azeotropic data are calculated with a thermodynamic model. Instead of calculating the homogeneous and heterogeneous points for many thousands of components, the DDB Components allows to choose a specific set of solvents. WebWhen the composition of a binary azeotrope is closer to 1:1 (as is the case for i-PrOH–i-PrOAc, for instance) solvent chasing from either solvent to the other will require less solvent. Some ternary azeotropes (solvent–solvent–water) that may be encountered are shown in Table 5.10 [36].
