Abstract
Excess molar volumes, changes of refractive indices, and changes of isentro pic compressibilities of the ternary mixture (acetone + methanol + n-heptan e) have been computed from density, refractive index, and speed of sound me asurements at T = 298.15 K and atmospheric pressure. These derived properti es were fitted to the Nagata equation and the correlation parameters determ ined. Despite the high non-ideality observed, the excess molar volumes were predicted by means of cubic equations of state with simple mixing rules. ( C) 2000 Academic Press.
