Y. Uosaki et al., STATIC RELATIVE PERMITTIVITIES OF 3 WATER+BUTANEDIOL MIXTURES UNDER PRESSURES UP TO 300MPA AT 298.15K, Journal of chemical and engineering data, 43(4), 1998, pp. 646-649
Static relative permittivities epsilon(r) of water + butane-1,2-diol,
water + butane-1,3-diol, and water + butane-1,4-diol in the liquid pha
se were determined from capacitance measurements over the entire compo
sition range under pressures up to 300 MPa at 298.15 K. The Tait-type
equation is applied to represent the pressure dependence of epsilon(r)
for each solution. The Tait-type parameters, A and B, are determined
from the nonweighted least-squares method. The composition dependence
of epsilon(r)(0.1), (partial derivative ln epsilon(r)/partial derivati
ve P)(T), and epsilon(r)-(2)((partial derivative epsilon)(r)/partial d
erivative P)(T) values at 0.1 MPa for the three binary aqueous butaned
iol mixtures are compared.
