Popis:	Densities of six binary, three ternary and quaternary mixtures formed by water, methanol, ethanol, and 1-propanol have been measured at 298.15, 308.15, 318.15, 328.15 and 338.15 K. The binary parameters of an NRTL-type equation for excess molar volumes were determined from the binary density data. The calculation of ternary and quaternary excess molar volumes with the binary parameters shows that the proposed method successfully estimates the excess molar volumes over the entire composition and temperature ranges with a reasonable accuracy.
