4) Construct a boiling diagram for the mixture:
system components (1-C2H5OH: component boiling point 78.3°C; azotropic mixture composition 30%; 2-CH3COOC2H5: component boiling point 78°C; azotropic mixture composition 70%) The boiling point of the entire azeotropic mixture is 72°C.
Determine the result of fractional distillation of a solution containing 20% CH3COOC2H5 and 80% C2H5OH.
