Abstract
The vapour‐liquid equilibrium data of the binary, ternary and quaternary systems that may be formed by combination of the components acetone, methanol, propan‐2‐ol and water, have been determined at 760 mmHg by means of an equilibrium still based on the principle of circulation of both phases. The binary data have been correlated by means of the Margules and of the Wilson equation. The data of the ternary and quaternary systems have been predicted by these equations. The results of both equations are discussed and compared.
