Abstract

The(p,Vm,T) behaviour of (heptane + 1-chlorobutane) was measured at the temperatures (298.15, 308.15, 318.15, and 328.15) K and in the pressure range 0.1 to 40 MPa with an accuracy in density of ±1·10-4g cm-3. An apparatus for the(p,Vm,T) measurement of liquids and liquid mixtures whose main part is a high-pressure vibrating-tube densimeter working in a static mode was used for the measurement. Excess molar volumes were calculated from the data and fitted to the Redlich–Kister equation.© 2002 Elsevier Science Ltd
