摘要：
Excess molar isobaric heat capacities of 2-propanone + heptane, + trichloromethane and + benzene were measured at 298.15 K. They were positive for the former two mixtures and changed the sign from positive to negative with increase of 2-propanone for the latter mixture. The results were discussed in relation to the local fluctuation of concentration. Excess isothermal compressions for these mixtures were calculated by using the present heat capacity data and isentropic compression results measured previously. The excess isothermal compressions were found to have similar composition dependence as those of the excess volumes for these mixtures. © 1990.
