摘要：

A bellows volumometer has been used to obtain volume ratios relative to 0.1 MPa for n-heptane at (278.15, 288.15, 298.15, 313.15, 323.15 and 338.15) K for pressures up to 400 MPa. A version of the Tait equation of state enables accurate extrapolation of the results to 198 K and to 363 K. Prediction of volume ratios with reasonable accuracy up to 423 K is possible if parameters of the critical point are included in the Tait equation. The isothermal compressibilities, isobaric expansivities, "internal pressures", and changes in isobaric specific heat capacity, have been evaluated from the results. © 1991 Academic Press Limited All rights reserved.
