Static relative permittivities epsilon(r) were measured for alkan-1-ols from methanol to octan-1-ol under pressures up to 300 MPa at 298.15 K. A Tait-type equation was used to represent pressure P dependence of epsilon(r) values for each alkan-1-ol, and the Tait-type parameters A and B were determined. By using the static relative permittivity at P-0 = 0.1 MPa epsilon(r)(P-0) and the Tait-type parameters, dielectric parameters at P-0 [(partial derivative epsilon(r)/partial derivative P)(T,P0), (partial derivative ln epsilon(r)/partial derivative P)(T,P0), and epsilon(r)(P-0)(-2)(partial derivative epsilon(r)/partial derivative P)(T,P0)] for alkan-1-ols were calculated at 298.15 K. Values of (partial derivative ln epsilon(r)/partial derivative P)(T,P0) and epsilon(r)(P-0)(-2)(partial derivative epsilon(r)/partial derivative P)(T,P0) for each alkan-1-ol from methanol to heptan-1-ol were correlated with the temperature T by a combination of the present values at 298.15 K and those evaluated from epsilon(r)(P) data at various temperatures from the literature. Effect of carbon number n in alkan-1-ol on the dielectric parameters was also examined at 298.15 K. The (partial derivative ln epsilon(r)/partial derivative P)(T,P0) values in this work were compared with those calculated from some relationships between (partial derivative ln epsilon(r)/partial derivative P)(T,P0) and the isothermal compressibility at P-0 [k(T,P0)].
