We show how one can compute residue curve maps (RCMs) for the methyl acetate and isopropyl acetate chemistries at atmospheric pressure. These computations involve solving a complex system of differential algebraic equations (DAEs). This can be readily achieved using the built-in functions of Mathematica and MATLAB. The governing equations, which depend on transformed compositions, are provided. Equations to compute vapor-liquid equilibrium when there is dimerization in the gas phase are given because of the presence of acetic acid in both quaternary mixtures. The occurrence of a chemical reaction leads to the disappearance of an azeotrope in the methyl acetate chemistry. On the other hand, a reactive azeotrope appears in the isopropyl acetate chemistry. Transformed compositions of these azeotropes are provided.
