Vapour‐liquid equilibria in ternary systems: II. The system acetone‐chloroform‐benzene

Abstract In this system the components are completely miscible in the liquid state. The boiling points and the equilibria liquid‐vapour at a pressure of 760 mm were determined. From the three binary systems only the system acetone‐chloroform has an azeotropic point, a maximum. The ternary liquid‐surface (boiling‐point‐surface) and the vapour‐surface have a ridge, going from the maximum on the acetone‐chloroform side, at 64.5° C and 78% chloroform, to the benzene point at 80.25° C.
