ISOTHERMAL COMPRESSIBILITIES OF BINARY-LIQUID MIXTURES OF 1,2-DICHLOROETHANE AND OF TRANS-1,2-DICHLOROETHENE AND CIS-1,2-DICHLOROETHENE PLUS N-ALKANES OR PLUS 2,2,4-TRIMETHYLPENTANE IN THE PRESSURE RANGE (0.1 TO 10) MPA AND AT 293.15 K

Isothermal compressibilities have been determined from density measure ments of the liquid mixtures of 1,2-dichloroethane, of trans-1,2-dichl oroethene, and of cis-1,2-dichloroethene + heptane, + decane, + dodeca ne, + tetradecane, + hexadecane, and + 2,2,4-trimethylpentane at press ures from (0.1 to 10) MPa and 293.15 K. The compressibilities were cal culated from a fit of the molar volumes to a modified Tait equation. T he data could also be correlated surprisingly well by a new linear p-V -T relationship suggested in the literature recently. This correlation makes it possible to judge the quality of the measurements.
