ABSTRACT

Densities and speeds of sound for (1,5-dichloropentane or 1,6-dichlorohexane) + dodecane in the temperature interval (278.15 to 328.15) K were determined using a tube vibrating densimeter and sound analyzer (Anton-Paar DSA-48). Isobaric heat capacities per unit volume for the same systems were measured in the temperature interval (283.15 to 323.15) K by means of a micro DSC II calorimeter using the scanning method. In all cases, measurements were made at atmospheric pressure. From these data, the molar volumes, isobaric and isochoric molar heat capacities, isentropic and isothermal compressibilities, and isobaric thermal expansivities as well as their excess quantities were calculated. Some comments related to the influence of the well-known effects of polar + long alkyl chain linear alkane on excess properties were included.
