The phase diagram for the given N,N-dimethylacetamide and heptane system against the mole fraction of N,N-dimethylacetamide in two phases has to be drawn. Concept introduction: The azeotropic mixture is defined as a mixture of two or more liquids which evaporates without altering the composition of the mixture. The azeotropic mixture has a constant boiling point because of the same composition in liquid as well as vapor phase. The components of azeotropic mixture are not separated by distillation processes. The phase diagram represents the changes in the mixture on changing the conditions like temperature and pressure of the mixture.
