EXCESS MOLAR VOLUMES OF TERNARY MIXTURES OF DI-N-BUTYLETHER PLUS 1-HEPTANOL PLUS N-OCTANE AT THE TEMPERATURE OF 298.15 K

Excess molar volumes of the ternary mixture {x(1) di-n-butylether + x( 2) 1-heptanol + (1 - x(1) - x(2)) n-octane} and the corresponding bina ry mixtures were measured at the temperature 298.15 K. Excess molar vo lumes were determined using an Anton Paar densimeter. The experimental values were compared with the results obtained with some empirical me thods for the estimation of ternary properties from binary results. (C ) 1997 Elsevier Science B.V.
